DESCRIPTION
Mazda (North America), Inc. (MANA) has been supplying rebuilt Electronically Controlled Automatic Transmissions (EC-ATs) for Turbo and non-Turbo models since October 3, 1988. These assemblies have been prepared with up-to-date modifications as described in bulletin Category 7, no. 051/88. MANA will also be supplying Hydraulic Automatic Transmissions (HATs) effective March 5, 1990.
This bulletin is provided for up-to-date information regarding the 1989 model year.
- Using the EC-AT tester, verify that the problem is not solenoid related and that the assembly has indeed failed.
- Before removing the failed assembly, an EC-AT/HAT Inspection Sheet (supplied by MANA, see attached), should be filled out with the customer. This inspection sheet, which should be returned with the failed unit and a copy retained with the repair order, contains information regarding this program.
- Refer to Mazda Parts Bulletin E-7-88 (Western Regions, revised 3/5/90), and V-32 (Eastern Regions, revised 3/5/90), for procedures required for ordering rebuilt EC-ATs and for instructions regarding the return of the failed assembly (i.e. draining instructions, part removal, etc.).
- Refer to Mazda Warranty Bulletin, Category K, no. 1 (revised 3/5/90), for the terms of this program. If replacement is necessary, you MUST contact your DSM for authorization.
MANA will supply an instruction manual containing installation and adjustment procedures with each rebuilt unit.
- Failure to fill out the EC-AT/HAT Inspection Sheet may result in the forfeiture of the core refund.
- DO NOT remove the VIN I.D. tag from the core - removing it would be a violation of Federal Law.
The following parts should remain on the core before returning to MANA. Refer to the illustrations below and the reference chart.
