Does anybody here have any idea about how much it would cost to replace V6 stang's tranny pan gasket & spedo stem o-ring? looks like it's having small leak...I was also told by my mechanic the other day that the rear axl seals and bearings need be replaced, how much should those be?

Any piece of advice is appreciated.

 

While you're down there, you should get a tranny flush/fill with a filter change. This will incorporate the price of the pan gasket. Should be $150 or less for all that. The speedo o-ring is about a 2 minute job with a $0.10 part. A reputable shop would pretty much throw that labor in if you give them the money for the tranny flush/fill.
