| Powertrain Control System |
- Electrical inputs/outputs, vehicle wiring harness, internal transmission wiring harness, PCM, EPC, TSS, OSS, Digital TR, TCS, TP, SSA, SSB, SSC, SSD and RPM
|
|
| 310 - HYDRAULIC/MECHANICAL ROUTINE |
| Fluid |
|
|
- Adjust fluid to correct level.
|
|
|
- Inspect fluid for contamination. If contaminated, locate the source of contamination. If burnt, inspect the mechanical band and clutches.
|
| Shift Linkage |
- Cable and bracket damaged, misadjusted, TR misadjusted
|
- Inspect and repair as required. Verify transmission shift cable adjustment; refer to TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS
.
Adjust transmission shift cable as necessary. After repairing transmission shift cable, verify the digital transmission range (TR) sensor is correctly adjusted. Adjust the digital TR sensor as necessary.
|
| Incorrect Pressures |
- Incorrect band and clutch application pressures, line pressure low
|
- Check line pressure at tap. Carry out line pressure and stall speed tests. See PRESSURE CHART for specifications. If pressure is low check main control, pump and EPC solenoid.
|
| Filter and Seal Assembly |
- Filter damaged, plugged; seal damage, cut or missing
|
- Inspect for damage and install new.
|
| Main Control Assembly |
- Screws out of torque specification
|
- Adjust screws to specification.
|
- Gasket damaged or off location
|
- Inspect and install a new gasket.
|
|
|
- Inspect for damage. Repair as required.
|
- SSA, SSB, SSC, SSD, EPC solenoid stuck, damaged, O-ring damaged or out of bore
|
- Inspect for damage. Carry out solenoid function test as listed in the electrical routine. Repair as required.
|
- Forward modulator valve/EPC boost valve (207), pressure boost valve/main regulator valve (208), extension housing lube orifice, check ball C damaged, spring damaged, missing, misassembled, stuck, bore damaged
|
- Inspect for damage. If damaged install a new main control. If parts are missing install new parts or main control. If misassembled, reassemble correctly. Do not stone, file or sand valves. This will remove the anodized finish and may result in further main control or transmission failure.
|
- Wrong components used during assembly
|
- Verify that the correct components were used.
|
| Front Band and Servo Assemblies |
- Band adjustment incorrect
|
- Readjust to correct specification.
|
- Seal or piston, strut, lever, damaged
|
- Inspect for damage. Repair as required.
|
- Friction elements worn damaged misassembled
|
- Inspect for damage. Repair as required.
|
- Return spring wrong, damaged
|
- Inspect for damage. Repair as required.
|
- Piston rod lever incorrect
|
- Inspect for damage. Repair as required.
|
- Case bore damaged, leaking
|
- Inspect for damage. Repair as required.
|
| Intermediate Band and Servo Assemblies |
- Band adjustment incorrect
|
- Readjust to correct specification.
|
- Seal or piston, strut, lever, damaged
|
- Inspect for damage. Repair as required.
|
- Friction elements worn damaged misassembled
|
- Inspect for damage. Repair as required.
|
- Return spring wrong, damaged
|
- Inspect for damage. Repair as required.
|
- Piston rod lever incorrect
|
- Inspect for damage. Repair as required.
|
- Case bore damaged, leaking
|
- Inspect for damage. Repair as required.
|
- Inspect for damage. Repair as required.
