Seal Installation Procedure (Figure 1)
To prevent automatic transmission fluid from leaking from the cooler line seals (49) after installing new seals, perform the following procedure.
Important:
Only GM Goodwrench DEXRON(R) III automatic transmission fluid should be used as part of warranty repair of GM Powertrain automatic transmissions.
Notice:
Failure to lubricate the cooler line seals (49) with automatic transmission fluid DEXRON(R) III, before installing the cooler line pipes into the seals, may cause damage to the seals.
1. Lubricate the inside surface of both new cooler line seals (49) with automatic transmission fluid DEXRON(R) III.
2. Place a new cooler line seal (49) into the case bore.
3. Install the cooler line seal installer tool J 41239-1 on the transmission case (51) at the cooler line bracket bolt hole.
4. Press the new cooler line seal (49) in by tightening the seal pressing bolt on the cooler line seal installer tool J 41239-1 until the seal bottoms out in the case bore.
5. Repeat steps 2 through 4 for the second cooler line seal (49).
