One or both transmission output shaft seals may leak. Our technicians tell us that worn bushings inside the transmission could be the cause of the damaged seals. Our technicians tell us that if a bushing is worn, excess play will be noted where the drive axle attaches to the transmission.

Noticed Transmission spots and took it to local shop. They informed me that it I needed to replace bushing and seal on the driver side, he also noticed a small antifreeze leak due to the gaskets around the water pump, also common. Transmission Tech said that its common on these kinds of cars to have this problem.

The problem is the bushing! A cheap part but the engine needs to be removed. Not cheap labor!! Part of the problem led from a failed engine mount that I have replaced and yes the trans leaks like crazy in reverse. Cost to repair about $1600.00. Do not let your trans run out of or low on fluid it will burn up.
