TORQUE SPECIFICATIONS
Pressure should be 524-565 kPa (76-82 psi) with
closed throttle and increase to 965 kPa (140 psi) at 1/2
to 3/4 throttle.
372-414 kPa (54-60 psi).
No more than 21 kPa (3 psi) lower than line pressure.
No more than 21 kPa (3 psi) lower than line pressure.
1103 kPa (160 psi) at idle, builds to 1862 kPa (270 psi)
at 1600 rpm.
Pressure should respond smoothly to changes in mph
and return 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.
