1994 - 2001 Saturn S-Series vehicles with automatic transaxles (RPO MP6 or MP7)
Some customers may comment about harsh transaxle shifting and/or erratic transaxle shifting. One or more transaxle-related diagnostic trouble codes (DTCs) may have set. The Malfunction Indicator Lamp (MIL) may or may not be illuminated depending on what DTC is set. The malfunction Indicator Lamp (MIL) may or may not be illuminated depending on what DTC is set.
One or more of the following DTCs may be set and indicate what circuits are affected:
DTC | Circuit Affected | Wire Color |
---|---|---|
P0740 - TCC Solenoid Circuit Low Voltage P0741 - TCC System Stuck Off | Circuit - 422 Circuit - 1526 | Tan/Blk Wht/Blk |
P0746 - PC Solenoid Circuit Low Voltage | Circuit - 1525 Circuit - 1530 | Red Drk Blu |
P0756 - Shift Solenoid 2 Control Circuit Low Voltage P0732 - Incorrect 2nd Gear Ratio | Circuit- 1526 Circuit - 1222 | Wht Lt Grn |
P0761 - Shift Solenoid 3 control Circuit Low Voltage P0733 - Incorrect 3rd Gear Ratio | Circuit - 1527 Circuit - 1223 | Lt Grn/Blk YelL/Blk |
P0766 - Shift Solenoid 4 Control Circuit Low Voltage P0734 - Incorrect 4th Gear Ratio | Circuit - 1527 Circuit - 898 | Lt/Grn Ppt |
P0789 - Shift Timing Solenoid Control Circuit Intermittent | N/A | N/A |
For all DTCs listed above, if one specific solenoid DTC is set, diagnose those DTCs first.
Due to normal powertrain vibration, the transaxle wiring may flex and cause a circuit to open inside wire insulation near transaxle connector. In some cases, insulation will look distorted at point of open circuit.
Perform procedure in this bulletin to replace transaxle connector (P/N 21024415).
For intermittent or difficult to duplicate transaxle shift complaints, perform
this procedure to verify transaxle wiring integrity.Important
Illustration shown is for DOHC engine (RPO LL0); SOHC engine (RPO L24) is similar.Important
A sewing "seam stripper" is an excellent tool for removing tape
from a wire harness. It cuts the tape without damage to the wires under the tape.Important
If wires are broken inside insulation, outside of insulation may appear to be
thin in one area, stretched or discolored.Important
When splicing in new connector, stagger crimp-and-seal connectors
so they are not all in same location. Staggering crimp-and-seal connectors will
allow for a better finished look.Important
For the wiring used in Saturn vehicles, it is recommended that only approved
Packard Electric Crimp and Seal Splice Sleeves (or equivalent) be used.Important
DO NOT USE A MATCH OR OPEN FLAME TO APPLY HEAT TO SPLICE SLEEVE.Caution
Do not over-tighten or damage tot he connector plate may occur.Notice

GM bulletins are intended for use by professional technicians,
NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to
provide information that could assist in the proper service of a
vehicle. Properly trained technicians have the equipment,
tools, safety instructions, and know-how to do a job properly and
safely. If a condition is described, DO NOT assume that the
bulletin applies to your vehicle, or that your vehicle will have
that condition. See your GM dealer for information on whether
your vehicle may benefit from the information. |
