The transmission is completely disassembled, cleaned, inspected, and re-assembled. The cable must be removed completely to free it up. Look numbers on transmission housing. In-Line Marine Transmissions The "71" and "72" designations of Borg-Warner marine transmissions indicate input horsepower ranges. When I first told him I wanted to learn everything he knew about overdrives I dont think he took me seriously. Locate the identification tag number. 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 experts all agree that cleanliness is the most important factor during installation, and the lack thereof is the most common problem that leads to bearing failure. No need to touch the lever and limited use of the clutch, what more could you ask for? (Ideally the cable should only be pulled out while the vehicle is stopped).When the OD cable is pushed in then the whole system just freewheels. After learning of Als background I knew I had found my. The M-35 case has provisions to be drilled for an external cooler, but no U.S. models used an external cooler and do not have the internal provisions to mount one. Borg-Warner was by far the largest transmission supplier in the industry, so it was only natural that they also began developing automatic transmission designs. At that time all vehicles were operated by a low horsepower (80-100HP) low compression engine, with a very long stroke (4+ inches would not be unusual).

The T-10s came with a 10-spline, 1.125-inch input shaft. To make it possible for a low power 1930s-40s engine to climb hills and haul loads manufactures installed very low rear axle ratios. This wire always seems to have a frayed spot. This is useful for economy in relatively flat terrain and for starting on slippery surfaces (wet mud, snow, ice, etc.).

Trucks used a two piece shaft with a yoke bolted to the output shaft. The M-37 is first mentioned in the 1967 AMC Technical Service Manual (TSM). Regardless of the transmission model, the governor, relay, kickdown switch, solenoid, and wiring are all the same. This synchro effect happens because the freewheeling clutch prevents power from being transmitted from the driveshaft into the transmission. It took less than a half dozen years to use up the supply of NOS (new old stock) parts to rebuild the overdrive solenoids.

If you shift into third gear before 28 mph (and engaging the OD) again there is no need to depress the clutch pedal to make the shift. Even after the war the overdrive option continued to be popular. Early models have two drive positions marked with a "2" and a "1" (P-R-N-D2-D1-L; Park, Reverse, Neutral, D2, D1 and Lock). The other wire goes directly to ground (part of the kick down circuit). The engine will rev up and when the pedal compresses the kick down switch, it will suddenly and quickly shift back into direct drive. Finishing techniques are available to address the specific performance requirements of each application, such as cut and molded groove patterns, multi-segment facings and waved cored plates. This is a cylinder shaped device that is driven by the speedometer gear with ONE wire coming out of it. You can read elsewhere about how the holding and releasing of the sun, planet and ring gears give various ratios, but for the purpose of understanding how a B-W OD system works all that needs to be remembered is that when the sun gear is held and the planets are driven by the transmission the output shaft, then more revolutions are sent to the driveshaft than went into the transmission.
