Rear Main Seal Leak

[Furnrep101]

I own a 03 GS300, has apprx. 108k miles at this point. Haven't had too many issues up until now. All of a sudden I noticed there was smoke rolling out from under my hood whenever I stopped at a light. Came to the conclusion that I have a rear main seal leak. Does anyone know if they make a Speedy sleeve for this year of Lexus? If so, is this a job that can be done in a weekend (replacing the seal and adding the speedy sleeve)?

Thanks for you help.

found a site that shows how to replace a LS400 rear main seal.. http://www.lexls.com/tutorials/transmission/removal.html Would this be the same process on the GS300?

Thanks.

Before I purchased a used 1999 RX300 from a Buick dealer; I had a Lexus Dealer do a Used Car Checkout.

They found a Leaky Main Seal.... and estimated it would cost $ 1400 ; since engine and trans had to be dropped.

Much Labor.

The Buick dealer said that they would honor the diagnosis and did the work, saying that the price was reasonable,

but they could do it with their own mechanics.

Hope this helps...and lets you make the shop vs DIY decision....
