Step 1. Remove oil pan (para 7-11). Manually shift transmission and see if the manual shaft and
detent lever are engaging with selector valve and that actuator pin is attached to detent
lever.
If selector valve does not engage replace defective parts (para 7-20).
If selector valve engages, disassemble transmission and valve body to check for
applied clutch packs or leaking or sticking valves in valve body (paras 7-15, 7-16,
7-17, 7-18, 7-19, 7-20).

Step 1. Check for low main pressure. Remove line from main pressure port on transmission and
install a tee and a 0 to 300 psi (0 to 2 068 kPa) gage. Start engine and allow to run at idle
speed. With parking brake applied, shift transmission into DRIVE. Check for 105 to 140 psi
(725 to 965 kPa) main system pressure.
If pressure is 105 to 140 psi (725 to 965 kPa), rebuild forward clutch (para 7-15).
If pressure is less than 105 to 140 psi (725 to 965 kPa), go to Malfunction 3, steps 1
through 3.
