I am posting this in 2 sections on the forum.
I have a 2000 Tahoe (New body style) with the 4L60 Transmission. I have around 102,000 miles on it and the trans is pissing me off. I was on my way to an important meeting today and it started acting up. As I pulled to the side of the road to look at my map, it downshifted hard. As I began to pull away it revved but only moved a little, so i hit the gas a bit more and it CLUNKED and CLUNKED, it's done this before once in a while but not all the time. I pulled onto a side street and went slow ( it sounds like something gets disconnected, it's a real weird CHATTERING sound) So I shut the truck off, waited 5 minutes started it and everything was fine. I know it's getting hot out and trans are running hotter, but I dropped the pan at 80k and flushed it with Amsoil synthetic fluid. The trans runs around 195 degrees so I dont think the fluid broke down. Is is MAYBE a transfer case problem? I can't stand when it does this and I am getting tired of it. ANY IDEAS? It seems like it takes longer to shift now since I have the A/C going full blast, not sure if that has anything to do with it.
