Various speed ratios are obtained by holding or clutching various combinations of elements of the planetary train. It was identified as an R-11 unit. The Novak Guide to the Borg-Warner T18 & T19 Transmissions Traveling salesmen in particular were fans, especially if they were working strictly on commission and had to buy their own fuel. (Especially with the ladies). You rarely ever need to lock out the system. Next insert the inner cable back into the outer sheave and spray the entire assembly with WD-40 or similar light oil. All three methods have been used over the years. You know those transmissions havent been around for 40 years, right? and Are you SURE you want to learn overdrives? he would ask me over and over. Tools. In the late 1940s the standard method used to control the engagement of the overdrive was by holding the sun gear stationery. [6] Frdric Lissalde has been CEO of BorgWarner Inc. since August 1, 2018. Remove the wire connections at the relay and the kick down switch and ensure that they are clean. If however you have allowed the transmission to engage the OD in second (backing of the gas) then depressing the clutch is necessary to shift from 2nd to 3rd. Count the number of bolts on the transmission cover. The kick down switch mounted to the firewall and the accelerator linkage that activates it. Freewheeling at speed is dangerous and can lead to loss of control due to increased brake use. If there is no relay click when grounding the governor, check for 12 volts at the wire and trace it back to the kick down switch and then back to the relay to find the open circuit. If you have 12 volts at the governor and you hear a relay click when you ground the governor, then the relay should be sending power down to the solenoid. We have the technology and experience to engineer cost effective solutions to your most demanding applications. Our Torsional Vibration Dampers offer stable damper characteristics over the products lifetime, minimal temperature impact on performance, excellent vehicle response and engine agility through low inertia, simplified system tuning in combination with DCT module and space efficient packaging. Al was an engineer by trade and was part of the team that designed the original R-10 and R-11 overdrives. If you have good power on both sides of the fuse on the OD relay, the next check is made under the vehicle. They never built a B-W OD transmission with a synchronized first gear. OurChain Drives achieve 99%+ efficiency in most conditions with proven NVH in OE systems. So to park safely (set the brake) and then either pull out the OD cable OR place the shifter into reverse. In terms of classic workhorse transmissions, the Super . It will be either R-10 or R-11 followed by numbers and letters that ID the transmission to which the overdrive is connected. The truck accelerates and the driver shifts into second gear. The specification-change from the Torqueflite automatic transmission[11] to the Borg-Warner 35 transmission was due to a requirement for more local content. Starting in 1967 (1963 for cars) the kick down switch migrated to the firewall and was operated by the throttle linkage. The transmission is equipped to produce kickdown and will upshift after kickdown if accelerator pressure is released following a kickdown. Manufactured by Borg-Warner Corporation, the overdrive option was offered on 22 different car models. There are 6 & 12 volt versions and it seems like everybody used their own different types of wire connections, but once the connections and voltages match up, most any component will work in any system. Fords and Mercurys received the B-W OD as an option in 1949 and the F-series trucks got OD for 1953. [5][6] The gear ratios from the Ford Falcon XD specifications are typical of all and are as follows:[7], The 5.8 litre V8 came equipped with the Ford FMX-3,[8] which was an evolved three-speed Ford-O-Matic (designed by Borg Warner Corporation), via the "MX" and "FX" (Cruise-O-Matic) transmissions to become the FMX[9] in 1968. The Novak Guide to the Borg-Warner T90 Transmission The engine will rev up and when the pedal compresses the kick down switch, it will suddenly and quickly shift back into direct drive. The M-37 is first mentioned in the 1967 AMC Technical Service Manual (TSM). Parking is the other situation that pulling out the OD cable is necessary. The kick down switch is a push button type switch that is operated only when the accelerator is fully depressed (mashed to the floor) Before 1967, Ford trucks used a switch design that goes all the way back to the 1930s. When the transmission of the motionless vehicle is placed in Drive, the transmission allows the vehicle to move off in first gear, then will change to second and then to third gear based on an increase in road speed. In a truck a low geared rear end could help it haul a heavy load but you dont want to spin the engine so fast at highway speeds or when the truck is empty. There are two wires on the solenoid. As it turns out, this question is often overthought. The five-speed transmissions fall into two categories: world class and non-world class. It is a good transmission when well maintained and has often been adapted to V8, V6 and I4 power. Excluding the variations of using a Chevrolet or Mopar OD transmission I will focus on Ford versions. Transmission Technologies - BorgWarner This listing can tell you what transmission you have and what vehicle it was originally designed for. They are found in Ford, Jeep and IH trucks. Drive in second gear OD, slow down below 28 mph and the trans falls out of OD and into freewheel mode. When they reach the magic speed of 28 mph, the wire going into the governor is grounded. BorgWarner - Wikipedia The demand for overdrive parts today is greater than ever. These operational features are what made the B-W OD transmission very desirable in the days before fully automatic transmissions. This means that while a B-W OD transmission has sometimes been called a 6 speed it is really provides only 5 practical forward ratios. Search by Number. Overdrive was last used in Ford passenger cars in 1967. This locks up the driveline and prevents all rolling. That's because they are a primary option in everything from Super Late Models all the way down to the Limited. Pulling out the OD cable on the dash operates a lever on the side of the transmission and mechanically locks the sun gear to the planetary gears.

There is a Throttle Valve in the control valve body that is connected to the throttle linkage via a cable. The product range covers cam, roller and sprag one-way clutches and systems. This regulates internal pressure by throttle position. We rebuild and repair Borg Warner & Tremec T5, T45, T56, 3550's, and TKO's. A standard rebuild will replace worn synchro's, bearings, and seals. The BW-35 will downshift from third to second and from second to first, also based on load. By selecting L from stationary, or before an upward gear change into 2nd gear, the transmission will become locked in 1st gear. By 1967 the M-36 was relegated to the 199 six, the 232 received the stronger M-37 in all AMC vehicles. When the OD cable IS pushed in, the first operating feature of the B-W OD transmission becomes apparent it freewheels. A B-W OD is electrically operated. The "3" in the number refers to the specific series of transmission. It uses a freewheeling clutch that began life in the 1920s and later added a planetary gear set (operated as a purely mechanical device in the early 30s) and eventually finalized the design by using electrical components to operate the system by the late 1930s. With Chevy/GMC Square Bodies all the rage, American Powertrain the nations leading distributor of TREMEC transmissions, is introducing a Square Body Chevy/GMC 44 kit for the TREMEC TR-4050 5-speed, 4WD manual transmission designed to fit 1973 1987 pickups and SUVs including Suburbans, Jimmys and Chevy Blazers. Owners manuals from that time suggested that around town you could (should?) Once the car was safely passed, the driver could just lift his foot and the transmission would shift back into overdrive. He had a lot of the information in his head, things he knew from memory, and never wrote down. There are many ways to overdrive a vehicle. After the 4 speed became available in 1962 request for the OD transmission declined but it did function just as intended by taming the very low rear end ratios that were commonly installed in high-performance cars. High-performance motor oils are an essential component of any engine build, providing critical protection and enhancing performance. All right you Flatty guys, here is a problem that[], The B.B. Fill both to the bottom of the hole with normal hypoid 90 wt gear oil as you would for any standard transmission. The LS engine is known for its cylinder heads, and there are tons of options available to upgrade the factory components. The second number refers to a specific variation. All models follow a quadrant which has six stations. At the back of the transmission is the governor. [11], Further information can be found in the annually published Sustainability Report.[12]. Further integration of shift rail actuators is an additional option. The mechanical components are very stout and as long as the transmission AND THE OVERDRIVE unit is filled with gear oil (see maintenance below) the only problems should be electrical, which are very easy to trouble shoot.Take an OD truck out for a test drive with the OD cable pushed in, if it freewheels above 28 mph (and you dont feel the automatic shift) the trans is OK but there is an electrical problem. If there is no power here, trace the wire back to the key switch to find the break. If you have determined that 12 volt power is being sent to the solenoid from the relay, the solenoid can be tested by providing it with 12 volts directly. I spent a total of nine years learning overdrives from Al before he passed on. It was formed as a fusion of companies including Borg & Beck, Marvel-Schebler, Warner Gear and Mechanics Universal Joint. or Best Offer. It is essentially the same as the M-35 except that it has provisions for an external transmission oil cooler. Ford first offered the Borg-Warner OD on Lincoln Zephyrs beginning in 1941. There is a shaft/rod built into the transmission that automatically accomplishes this whenever the transmission is put into reverse. Language links are at the top of the page across from the title. BorgWarner Part Number. A planetary gear set is what exists in most automatic transmissions. Pull it apart and ground the wire that was going to the governor). Separator plates are "where the heat goes" during a shift and are another important component of the clutch system. BorgWarner Inc. is an American automotive supplier headquartered in Auburn Hills, Michigan. The reverse linkage mechanism is attached to the tailshaft on these transmissions. The mot important thing to know is that there are TWO places to add 90wt gear oil in the transmission. A complete overdrive transmission must be used. To try to start out from a standing start in overdrive would create an incredible strain on the driveline is certain to damage something or at least result in increased clutch wear. (start & stop, no hills and speeds that do not exceed 40 mph). The early overdrive transmission is actually a two-speed planetary transmission attached to the rear portion of a standard three-speed transmission. These models start off in Second gear when in the D2 position. The transmission has a date code stamped on the side of the case. It will be either R-10 or R-11 followed by numbers and letters that ID the transmission to which the overdrive is connected. Studebaker probably made more OD-equipped vehicles than anybody. org-Warner overdrive transmissions were first introduced in 1934, originally designed to reduce engine rpms at highway speeds. [5] BorgWarner is one of the 25 largest automotive suppliers in the world. Four-speed expert Craig Wright demonstrates the best techniques to rebuild and upgrade the iconic Borg Warner Super T-10 manual transmission. Push in the clutch and there are NO forces on the gears. In my research on the overdrive transmissions I was introduced to Al Weaver who was then in his upper 70s. Turns out a B-W OD trans doesnt need to be synchronized! The main reason you cannot add the OD parts to an existing 3 speed trans is the need for a shaft/rod to pass from the gear box into the OD unit to automatically lock out the OD freewheeling clutch whenever it is shifted into reverse. A Borg-Warner OD has sometimes been called a cable-operated overdriveIT IS NOT! Cars used a one piece driveshaft with a slip yoke in the trans. And DO NOT use modern synthetic gear oil in the overdrive transmission. An overdrive ratio can also be created with a planetary gear set. Search by Number. These ratios made it possible to climb a hill (road building technology was equally behind 21st century techniques, grades were steeper back then) but would also spin an engine very fast at highway speeds. While it seems like it might be difficult to add or repair a factory type Borg-Warner overdrive system, once you learn how to use the system to its maximum potential and versatility you will find it well worth the effort. The BW-35 was also manufactured in Australia from 1963 and was used on numerous Australian made cars. 4EAT-GF 4EAT-G FORD & GF4A-EL GF4A-HL MAZDA, A500 40RH 42RH 42RE 44RE A904 32RH 30RH TF-6, A518 46RH 46RE A618 47RH 47RE DODGE & JEEP, F4A41 F4A42 F4A51 F5A51 R4A51 V4A51 R5A51 V5A51, '90-'97 ACCORD 4cyl, 2.2CL, '95-'97 ODYSSEY, '96-'00 CIVIC BDRA S4RA B4RA B46A M4RA A4RA, CIVIC DX, EX, LX, '97-'98 B4RA B46A M4RA, 6F24 A6GF1 A6LF1 A6LF2 A6LF3 A6MF1 A6MF2 A6MF2H, F4A41 F4A51 F5A51 F5A5A A5GF1 A5HF1 HYUNDAI, W5A580 W5A330 NAG1 W5J400 CHRYSLER DODGE JEEP, MITSUBISHI BUILT INCLUDING DODGE & CHRYSLER, F5M51 F5M42 F5M33 F5M31 W5M32 W5M33 W5M51, MTX5 MTX75 M5TX M5TXA KSP5FW TR5A TR5B TR5C CAP5, FS5W71 FS5W71A FS5W71C FS5W71E FS5W71G FS5W71H, RS5F50 RS5F50A RS5F50C RS5F50V RS5F51 RS5F51A, NV3500 GETRAG 290 5LM60 NV3550 NV2550 NV1500, TOPLOADER 3-SPEED RAT RAN RAC RAB HEF HEG, TOYOTA C50 C51 C52 C56 C59 C60 C140 C150 T50, TOYOTA LEXUS SCION E52 E57 E250 E350 E351, TREMEC T170: SROD, RUG, RTS, T176, T177, HEH, DANA 18, DANA 20, DANA 24, DANA 28, DANA 300, KM100 KM120 KM150 KM155 KM190 KM195 KM272, MP1522 MP3010 MP3015C MP3022 MP3023 JEEP & DODGE, NP218 NP219 NP228 NP229 NP128 NP129 NP119, TRANSFER CASE GASKET & SEAL OVERHAUL KITS, 4T65E TRANSMISSION SPRAG FOR 3RD (Pawl Type) BY BORG-WARNER FITS PAWL TYPE '03-'08 GM & VOLVO (24216517), '69+ 180, 4L30E, A4S310R, DOUG NASH 4+3, & L82-'86 700-R4 TRANSMISSION 3RD CLUTCH SPRAG (26 ELEMENTS) BORG-WARNER, 200C 200-4R TH2004R TRANSMISSION INTERMEDIATE FLEX BAND BY BORG-WARNER FITS '76-'90 GM CARS, 350 TH350 TRANSMISSION LOW/REVERSE SPRAG BY BORG-WARNER FITS '69-'86, 45RFE 5-45RFE 65RFE TRANSMISSION LOW ROLLER CLUTCH (14 ROLLERS) FITS '99+ DODGE & JEEP, 4L30E 4L60E 4L80E 4T80E TRANSMISSION EPC SOLENOID UPDATED BY BORG-WARNER BOTTOM PRONGS (24209276), 4L60E 4L65E 4L70E 700R4 TRANSMISSION INTERMEDIATE BAND HI-ENERGY BY BORG WARNER FITS '82+, 4L60E 4L65E 4L70E 700R4 TRANSMISSION LOW REVERSE SPRAG 8673544 BORG-WARNER O.E. There were only a few variations made for all the years that OD was used. How To Rebuild a Borg-Warner Super T-10 Four-Speed Manual Transmission There is an opportunity to help your customers with their overdrive transmission, and once they find out you have the knowledge and replacement parts they will quickly spread the word. If the transmission does not freewheel (This can even be checked with the transmission out of the car) then it should be assumed that the overdrive compartment was not filled with 90 wt oil and the planetary gears are seized. This means that while the engine can drive the wheels, when the vehicle coasts, no power is fed back to the engine. Speaking of rear end gears how are they affected by the overdrive? BorgWarner. Al later traveled for the Borg-Warner Co., conducting classes for the technicians on how the overdrive transmissions worked and how to troubleshoot them. The Jeep T4 / T5 has a 23 spline output shaft for connecting to the transfer case input shaft. Knowing what numbers mean Borg Warner might save you a trip to the computer. Production was transferred in 1960 to the Borg-Warner plant at Letchworth in Great Britain.

BorgWarner Part Number. The OD cable and dash bracket. The next logical step was to offer a rebuild service for solenoids, among the most common wear items. In "Lock" the transmission can be locked to prevent upward gear changes and will provide maximum engine braking in 1st gear and moderate engine braking in 2nd gear. BORG-WARNER Products - Transmission Parts Distributors So in 2012 I began to have the solenoids reproduced along with the relays. Distributor Search. from when overdrive transmissions were common, so many of your customers will need to jog their memory on how the overdrive transmissions worked. This event can be very surprising to someone who is not familiar with the operation of an OD transmission as suddenly there is NO engine braking! With a functional OD you get the best of both worlds, strong low end pulling AND practical highway and unloaded use. In addition, lower differential ratios differentials were usually used in other automatic transmission applications to improve gas mileage (again due to the inefficiency of the earlier automatics, especially when used with small engines). The planetary unit is the heart of the overdrive and its engagement is controlled by one of three ways by the pinion gear, the internal gear or by the sun gear. T10 Borg Warner 4 Speed Transmissions Information and parts One of the most popular 4 speed transmissions is the Muscle Car 4 speed Borg-Warner T10 manual transmission. (see picture) These T-85/R-11 transmissions are strong enough that they were used behind the most powerful FE engines. Various types of solenoids, including low-leak, proportional, direct-acting, on-off and pulse-width modulated valves. At the same time, Borg-Warner Automotive Inc. was created as a subsidiary of the new company; the mother company, the new Borg-Warner Corporation, was later known as Borg-Warner Security Corporation. Borg Warner T10 Date Codes - Car Transmission Guide (Some systems use a strange kick down switch at the carburetor but the basic function is all the same) So if you need a relay or solenoid you can use one from a Chevrolet, Rambler or Studebaker etc. Borg Warner Velvet Drive Transmissions | Inboard Marine Gears - SKIDIM Work it a bit and then it should move very easily. The upper bolt on the solenoid secures the bracket that holds the outer cable. R-11 was for heavy-duty applications, including the bigger, heavier cars like Packard and Lincoln, and higher horsepower applications in later years. These stickers are most commonly found on Borg Warner transmissions.

Step 1. super-novass (15,295) 100%. AMC called this "Shift-Command" to differentiate it from the D2/D1 models, since either could be ordered in an AMC/Rambler automobile from 1965 to 1967. From 90mm to 900mm in diameter, we have the right friction material for your application. How to Identify a Borg Warner Transmission | It Still Runs The first thing I did after I got my education from Al was to write a book on how the overdrive works, how to operate it and how to troubleshoot it. Taunus TC1 & TC2 (Except 1.3L engine option), Cortina Mk1, Mk2 & early Mk3 (later Marks used Ford C3), This page was last edited on 9 April 2022, at 09:12. (8 k.p.h.). Modern gear oils are up to GL-5 or higher now, but the modern detergents in the gear oil will attack the bronze parts inside of the transmission. He shared a lot of his technical wisdom on overdrives that never made it into any shop manual. We offercomplete design, analysis, development and testing capability to support almost any wet friction clutch application. This article is to explain this unique transmission and its features to Ford truck owners & enthusiasts in the hopes that they will have a better .
