Once the leak has been pinpointed and traced to its source,
the cause of the leak must be determined for it to be properly repaired. For
example, if a case component is resealed but the mating surface is damaged,
resealing will not repair the leak. The damaged mating surface must be
repaired or replaced. Before attempting to repair a leak, certain conditions
should be checked for and corrected if necessary. The following conditions
may cause a transmission oil leak.

major case components. GM P/N 12346240 (Canadian P/N 10953493),
or equivalent, should be used where applicable.
