Test Procedures: Notes

Carry out the following procedures:

1. Drain the transaxle. Remove main control cover.
2. Remove the main control as an assembly with the solenoid body assembly.
3. The inoperative clutches can be located by applying air pressure into the appropriate clutch port. Refer to AIR PRESSURE TEST PORT LOCATIONS .
4. Install Transmission Test Plate 307-301 using six bolts.
   CAUTION: The coast clutch circuit should not be applied unless air pressure is maintained in the forward clutch circuit. Failure to do so can result in the coast clutch piston coming out of the forward clutch piston.
   NOTE: Refer to BAND AND CLUTCH APPLICATION CHART A  and/or BAND AND CLUTCH APPLICATION CHART B .
5. Apply air pressure 275 KPa (40 psi) to the appropriate clutch port (refer to AIR PRESSURE TEST PORT LOCATIONS  diagram). A dull thud may be heard, or movement felt when the clutch piston is applied. If clutch seals or check balls are leaking, a hissing may be heard.
