TECHNICAL SERVICE BULLETIN

APPLICABLE MODELS/VINS

1994 626/MX-6 (with 4 cyl. engines and automatic transaxles) from vehicle introduction through August 31, 1994.

DESCRIPTION

An exchange program has been established for the first year of service on the new LA4AEL transaxle. This transaxle is used in 1994 626/MX-6 (4cyl.) models. This program will provide quick response to customer complaints and feed back information leading to early transaxle failure.

The program is effective from the time of vehicle introduction through August 31, 1994  . During this period, the preferred method for repairing automatic transaxle failure is replacement.

A Technical Assistance Center and toll free "800" number have been established to administer the program. Assistance will be available Monday through Friday (except holidays) 8 a.m. to 5 p.m. (EST) by dialing 1 800 820-6262. If you hear a recording, leave a message and a technical assistant will return your call.

Confirm that the above material is in the exchange unit information package. If not, call the "800" number for replacement.

      NOTE: If leaks are found, call the Technical Assistance Center at 1 800 820-6262 prior to repair.
   2. Test drive the vehicle to verify the customer complaint.

      • Vehicle Speed Sensor (VSS)
      • Transaxle Solenoid Body Connector
      NOTE: If no problems are found, perform steps "d" through "f". If the connectors are disconnected, reconnect and verify that the complaint is fixed. If the complaint is not fixed, perform step "d" through step "f".
   4. Retrieve fault codes using the "Quick Test" and the Super Star II Tester (P/N 49 UN01 056).
   5. Perform the pin point test on any fault codes found. Refer to section K2 of the workshop manual .
