It was hydraulically shifted and controlled, with the only electronically controlled component being the torque converter clutch solenoid — just like the 3-speed automatic C that was available for the Pontiac Fiero. The T4 differed from the C in one major aspect besides the fact the T4 had an overdrive gear; it also had a vacuum modulator that controlled line pressure. On the C, both line pressure and shift points are controlled by the throttle valve TV cable aka: kickdown cable. The TV cable on the T4 only controls shift points. The individual gear ratios in the T4 are as follows: 1 st The T4 was available with the following differential ratios: 2. The drive chain attaches the input shaft to the rest of the transmission clutches, gears, and shafts, so a change in the chain sprocket ratio will impact all gears which will affect the overall final drive ratio.
