Transmission Leak Transmission slips in gear

My transmission leaks and slips

GM has issued a TSB #08-07-30-009A regarding a Transmission Leak Transmission slips in gear. The TSB applies to ALL 2001-08 GM vehicles with front wheel drive and the 4T80-E transmission. The TSB advises dealers NOT to replace the transmission for this defect. The fix is to replace the 3rd clutch housing with a new part #8682114. The new part is made from an updated material to extend the life of the axle seal.
