A/T - A4LD Front Seal Blows Out

TSB 87-43 (Jul)

SUBJECT: A4LD

PROBLEM: Front Seal Blowout

SOLUTION:
When servicing the A4LD transmission for front seal blowout, check the following:

1. Pump bushing to converter hub clearance should not exceed .003 inch.

2. Check for restriction in the drainback passage between the front seal and bushing.

3. Always use the proper front seal for the A4LD only - Part number E5TZ-7A248-A.

The front seals are now being staked in by the manufacturer. DO NOT REMOVE A STAKED SEAL and REPLACE IT WITH A NEW SEAL, WITHOUT STAKING THE SEAL IN PLACE.

A special tool is available to stake the seal in place.

Check with your supplier for more information, and the availability of the seal staking tool.
