Transmission Leak From Output Shaft Seal on Cadillac DeVille

Problem Description and Possible Solution

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.
transmission fluid leaking at driver side output shaft. New oil seal didn't fix. Needs bushing replaced, cost is extremely high.
Dr. side trans output shaft seal began slow drip.Costs around $5.00. time to repair 90 minutes. cost of labor $138.00
Small transmission fluid leak on driver's side front. First noticed after reverse. Local dealer changed the seal and the axle, then a major leak within 24 hours. Worse leak in reverse gear, and now they say they need to replace the bushing at the end of the axle, which requires the transmission be removed - and a cost of $1,500 to $2,000.
Transmission shop said the internal bushing on drivers side is bad so I'm having to add fluid since it leaks now.i might as well rebuild the tranny since it's only a few hundred dollars more they said but my tranny shifts great so I don't see a need to rebuild it and money is tight at the moment I'm still paying for last years cancer treatments
