Direct Clutch Pressure Test
NOTE:
Shift quality is affected when test gauges are attached to transmission. DO NOT
accelerate or decelerate rapidly during test. Transmission failure could result.
- Attach pressure gauges capable of reading 300 psi (21.1 kg/cm2 ) to the forward clutch pressure tap and the direct clutch pressure tap. See Figure. Mount gauges inside vehicle.
- Drive vehicle. When pressure is applied to the direct clutch, note pressure difference between forward clutch pressure reading and direct clutch pressure reading.
- If the difference is less than 15 psi (1.05 kg/cm2 ), direct clutch circuit is okay. If difference is greater than specification, there is a leak in direct clutch pressure circuit. Repair as necessary.
