Pressure Test
WARNING: This page is about a different variant/trim than selected.
| Item | Part Number | Description |
|---|---|---|
| 1 | - | Clutch C1 |
| 2 | - | Clutch C3 |
| 3 | - | Clutch C2 |
| 4 | - | Lube circuit |
| 5 | - | Clutch B2 |
NOTE:
If the pressure is low at stall, do not continue with the test or further transaxle damage will occur. Do not maintain Wide Open Throttle (WOT) in any transaxle range for more than 5 seconds.
This test verifies that the pressure is within specification.
- Connect the Transmission Fluid Pressure Gauge to the appropriate pressure tap.
- Start the engine and check the pressures, see the pressure charts to determine if the pressures are within specification.CLUTCH AND BRAKE PRESSURE CHART
Clutch Range Pressure C1 Drive (1st-4th) 196-1,372 kPa (28-199 psi) C2 Drive (4th-6th) 196-1,372 kPa (28-199 psi) C3 Drive (3rd-5th) 196-1,372 kPa (28-199 psi) C3 Reverse 392-1,863 kPa (57-270 psi) B2 Low manual (1st) 588-1,372 kPa (85-199 psi) B2 Reverse 392-1,863 kPa (57-270 psi) PRESSURE DIAGNOSTIC CHARTTest Results Possible Source Values of both DRIVE and REVERSE ranges are lower than the standards - Pressure Control Solenoid A (PCA)
- Primary regulator valve failure
- Transmission oil pump failure
- Leak from hydraulic circuit of DRIVE or REVERSE range
Only the value of DRIVE range is lower than the standards - DRIVE range hydraulic circuit failure
- C1 clutch failure
Only the value of REVERSE range is lower than the standards - REVERSE range hydraulic circuit failure
- C3 clutch failure
- B2 brake failure
- If the pressure is not within specification, install a new main control valve body.
- If the pressures are OK, clear all DTCs. Test drive vehicle, code could be intermittent. If DTC returns, install a new valve body.
