Rear oil seal leaking?

If the oil seal is leaking,then it has to be inspected and replaced.To replace oil seal,the transmission and starter has to be removed.Its not very hard task,but you should have proper tools and experience to do this.
If you have a minor leak you may be able to cure it with AT205, a seal swell made by the ATP company. I have seen this seal swell do miracles with many different fluid leaks - it is not cheap but if it can't fix it, only a wrench can!!! I suggest adding at least 2 pints to your motor and see if it stops it. Failing that, the job is relatively easy if you have a lift and the proper tools. If no lift, but a concrete floored garage, it is not so bad with a rolling floor jack. Alignment is always a problem so removing the bolts for the motor mounts and having 2 rolling jacks will help lots.With the proper tools and equipment, this job is not hard. the automatic transmission can be heavy, so a good floor jack with a transmission adaptor would help. You will need to support the engine while the tranny is out. make sure you mark the driveshaft where it attaches to the rear end so that it gets installed in the same position. You will also need to support the transmission while your removing the cross member that holds the transmission up.A person that has a fair amount of tools and a little more than basic knowledge should be able to accomplish this in one day.

This details will help.
