Step 1. Check for low main pressure. Remove line from main pressure port. Install tee and 0 to
300 psi (0 to 2 070 kPa) gage. Start engine and allow to run at idle speed. With parking
brake applied, shift transmission into DRIVE and accelerate engine to approximately
1200 rpm. Check for 140 to 175 psi (965 to 1 206 kPa) main system pressure.
If pressure is 140 to 175 psi (965 to 1 206 kPa), disassemble transmission and
inspect forward and first clutches for damage (para 7-15, 7-16).
If pressure is not 140 to 175 psi (965 to 1 206 kPa), go to Malfunction 3, steps 1
