Control Valve Solenoid Replacement (SS1, SS2, SS3, TCC, and MAIN MOD)
Control Valve Solenoid Replacement (SS1, SS2, SS3, TCC, and MAIN MOD)
Removal Procedure
1. Remove the oil pan and the transmission internal oil filter. Refer to Oil Pan Replacement Service and Repair.
2. Disconnect the internal wiring harness from the solenoid being changed.
3. Remove the solenoid retainer (2) for shift solenoid 1 (SS1) (5). Note the position of the solenoid connector and pull the solenoid (5) out of the bore in the control valve assembly (1). The O-rings (3 and 4) provide the resistance felt during removal.
4. Remove the solenoid retainer (6) for shift solenoid 2 (SS2) (1) or shift solenoid 3 (SS3) (4), whichever is being replaced.
5. Note the position of the solenoid connector and pull the solenoid out of the bore in the control valve assembly. The O-rings (2 and 3) provide the resistance felt during removal.
Note: The TCC pressure control solenoid (PCS) retaining bracket must not be modified. Note that the angle between the 2 bracket surfaces is less than 90 degrees. Replace the bracket if the angle is 90 degrees or greater.
6. Remove the TCC PCS retaining bolt and retaining bracket.
7. Remove the TCC PCS (7).
Installation Procedure
1. Obtain a new SS 2 (1), SS 3 (4), TCC PCS (7), or modulated main pressure solenoid. Install O-rings (2 and 3) and lubricate with clean transmission fluid. Push the new solenoid into the control valve assembly (5) with the wiring harness connector in the correct position.
2. Install the solenoid retainer (6). Connect the internal wiring harness to the solenoids replaced.
3. For a new TCC PCS (7), install O-rings and lubricate with clean transmission fluid. Push the new TCC PCS (7) into the control valve assembly with the wiring harness connector in the correct position.
Caution: Refer to Fastener Caution Fastener Caution.
4. Install the TCC PCS retainer and bolt.
Tighten the bolt to 12 Nm (108 lb in).
5. For a new SS 1 (5), install O-rings (3 and 4) and lubricate with clean transmission fluid. Push the new SS 1 (5) into the control valve assembly with the wiring harness connector in the correct position. Install the solenoid retainer (2).
6. Install the oil pan and transmission internal oil filter. Refer to Oil Pan Replacement Service and Repair.
Note: The FastLearn, adapt, procedure must be performed. This can be done in 1 step using a scan tool. If this procedure is not done, the TCM adaptive values will be at the settings that it learned for the old components and will be in slow adaptive mode. Under these conditions, it will take an unacceptably long time for the adaptive values to converge to levels suitable for the new transmission.
7. Perform the FastLearn procedure. Refer to FastLearn Procedure Programming and Relearning.
