If inspection of the transaxle at the time of disassembly reveals any form of internal damage, the transaxle cooler and cooler lines should be cleaned and flushed using the procedure provided in Section 7A of the 1982 Omega and Cutlass Ciera Chassis Service Manual, page 7A-2.
Also, only Loctite No. 515, Part Number 1052756 should be used at the case cover to case gasket to prevent leaks in this area.
Before using Kent-Moore Tool J-28535 (Intermediate Band Apply Pin Gauge) it should be checked and recalibrated per instructions in the 1982 August Service Guild page 82.
