NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 41TE/AE BUILT BEFORE AUGUST 8, 1998 (MDH O8O8XX) OR 42LE TRANSAXLE THROUGH THE 1997 MODEL YEAR.
SYMPTOM/CONDITION:
Intermittent loss of speed control condition persists after either the transaxle input speed sensor or output speed sensor has been replaced. The sensor connectors should be checked for spread terminals.
DISCUSSION:
The input/output speed sensor supplier changed effective with the 1998 model year for LH vehicles and August 8, 1998 for 41TE/AE equipped vehicles. The terminal layout is slightly different between the old and new sensors. When a new sensor is installed on an early vehicle the connector terminals may be spread from the original sensor and may cause an intermittent speed control condition. Anytime a new sensor is installed on an early vehicle the connector must also be replaced.
PARTS REQUIRED:
1 05014469AA Wiring Repair Package, Input Speed Sensor
1 05014471AA Wiring Repair Package, Output Speed Sensor
REPAIR PROCEDURE:
1. Disconnect and isolate negative battery cable.
2. Raise vehicle on a suitable hoist.
3. Locate and disconnect the input and/or output sensor connectors.
4. If required, detach the harness clip above the input/output sensors and detach the O2 sensor fastener (Christmas tree type fastener).
5. Remove the end tape from the input/output harness and push back the convolute tubing.
6. Cut the harness just above the top of the connector to remove the input and/or output connector.
7. Remove approximately 1/2 inch of insulation from the end of the two wires.
8. From the wiring repair package, locate the wiring repair harness. Approximately 1/4 inch of insulation has been removed from the repair harness wires.
9. Place a heat shrink tube over each of the two wires on the repair harness.
10. Using Miller Crimp Tool # 8272 or equivalent, crimp the splice band to the transmission harness and repair harness wires. Repeat procedure for the second wire.
11. Solder the connection together using rosin core type solder.
12. Center the heat shrink tube over the splice joint. Heat using a heat gun until the tubing is tightly sealed and sealant comes out of both ends of the tubing.
13. Cover wires with attached convolute and add additional convolute from the repair package.
14. Tape ends with black electrical tape.
15. Route engine harness behind the coolant lines and dipstick tube, away from the exhaust.
16. If required connect O2 sensor fastener and attach upper harness clip.
17. Connect input/output sensor connectors.
18. Connect negative battery cable.
19. Verify transmission systems are functioning as designed.
POLICY: Reimbursable within the provisions of the warranty.
