Transaxle Oil Leak Repair

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 transaxle oil leak.
