This gasket extends out beyond the sealing surfaces of the converter and transmission housing to prevent water from settling on the transmission housing. Standing water (especially salt water) can corrode magnesium in as little as eight weeks.
When replacing the aluminum bolts with new, a specific torque procedure should be followed for the best results. The procedure is simple and easy but finding theinformation took some effort – thanks Eddie!
The bolt torque procedure for the Converter Housing to Case bolts is as follows:
Stage 1 - Tighten to 10 Nm (88.51 in-lbs)
Stage 2 - Turn an additional 90 degrees
