(This is how a Borg-Warner OD transmission accomplishes an overdrive ratio). Combining Friction Plate and Separator technology, we offer single sided friction plates and collated packs. Initially produced in the U.S. in the 1950s specifically for engines of less than 200 cubic inches engine displacement and less than 140hp (100kW) (American Motors Rambler and Studebaker mainly). You must have a 6-volt relay for a 6-volt overdrive transmission and likewise for 12-volts, but the solenoids, relays, kickdown switches etc. As it turns out, this question is often overthought. However, to maximize its full operating potential, the driver must understand what it does and how it works. As is common in automatic transmissions of its generation, power brought to the transmission via the torque converter drives hydraulic fluid. The transmission has a 7-1/2" input shaft (stick-out length) with a 1-1/8" x 10 splines for AMC I6 engines and a 1" x 14 spline for the AMC 2.5 I4 engine.
