Sounds good Now I just have to determine what it is going to cost to fix. My alfa is very tempermental on the type of gear oil and engine oil needed so I am familiar with the subtlety. I just was not aware for my yukon that I needed to use anythingelse other than making sure the brand I chose said it was for that year model gm. Live and learn. Do the clutch packs, solenoids, bands etc. come as part of a rebuilt tranny as a unit? It seems if there is no specific electronic component or solenoid that affects 3rd and 4th gear I'm looking at putting a rebuilt transmission in. Since it shifts into 3rd and then slips I am assuming it is likely clutch pack unless someone can advise me otherwise.
