Air Pressure Tests
WARNING: This page is about a different car, the 2002 Mazda 626 and 2001 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect negative battery cable. Remove air cleaner assembly. Disconnect transaxle harness connector. Compress tabs on transaxle electrical harness receptacle and push into case. Raise and support vehicle.
- Remove drain plug and drain fluid. Remove left front fender splash shield. Secure cooler lines away from main control cover assembly (side cover). Remove main control as an assembly with solenoid body assembly.
- Install Transaxle Test Plate (T94P-77000-S) using 6 bolts. Air check clutch hydraulic circuits for function and leakage. Apply about 40 psi (2.8 kg/cm2 ) air pressure to appropriate clutch port. See Fig 1.
- A dull thud may be heard, or movement felt when clutch piston is applied. If clutch seals or check balls are leaking, a hissing sound may be heard. If leakage is detected, disassemble transaxle and inspect. Remove test plate.
- To complete installation, reverse removal procedures. Tighten drain plug to 97-115 INCH lbs. (11-13 N.m). Add 6 qts. (5.7L) of Mercon ATF. Start and run vehicle. Add fluid as necessary.
CAUTION:
DO NOT air check coast clutch unless air pressure is maintained in forward clutch circuit, or piston may be forced out of forward clutch piston.
