Third gear only No more than 21 kPa (3 psi) lower than line pressure.
1 range No more than 21 kPa (3 psi) lower than line pressure.
R range 1103 kPa (160 psi) at idle, builds to 1862 kPa (270 psi) at 1600
rpm.
D range closed Pressure should respond smoothly to changes in mph and return
throttle to 0-7 kPa (0-1.5 psi) when stopped with transmission in D, 1, 2.
Pressure above 7 kPa (1.5 psi) at stand still will prevent
transmission from downshifting.
