Affected Chrysler Intrepid Models:
1998-2002 2.7L, 1998-2001 3.2L, 1996-’97 3.3L and 1996-2002 3.5L

Symptom: Automatic overdrive transmission goes into second gear (limp-in mode) and will not shift, and trouble codes for the transmission solenoid pack are stored in memory.

Codes: P0750, P0755, P0760 and P0765

Problem 1 of 3: The transmission or electronic automatic transaxle (EATX) relay has a slower than normal response time causing the transmission control module (TCM) to set solenoid codes.

Test & Fix: Testing the response time of the transmission or EATX relay is usually unreliable. A quick test is to swap the relay with an identical relay on the vehicle or just replace it and retest.

Problem 2 of 3: The transmission solenoid pack has a solenoid winding that has higher or lower than normal resistance.

Test & Fix: Unplug the 8-way solenoid pack connector and check the resistance of each of the solenoid windings. Normal resistance is 1-3 ohms. Replace the solenoid pack if one or more solenoid windings have higher than normal resistance.

Problem 3 of 3: The TCM has one or more failed solenoid drivers.

Test & Fix: A labscope may be used to show that one or more solenoid drivers in the TCM is not fully grounding...
