The transmission in my Bonneville has been slipping and just overall acting up lately. I decided to change the fluid and filter to aid it, but it didn't make it any better. Car has 150k miles on it, and I believe the transmission was changed back when it had 30k on it becuase of some GM recall or something.
Anyway, I was wondering how big of a project it is to rebuild the transmission, or where I could get a refirbished one or if I could just take the transmission itself into a transmission shop and have them do it. (Prices on both options) It'* a nice car, the transmission issues just make it a pain to drive.
I did some looking around and I found this thread Remove transmission primarily 96-99
I'm assuming it is about the same as my car. Also found this thread about diagnosing it Transmission trouble shooting guide
I'd want to pull it apart and just rebuild the whole transmission. Is this excessively hard with basic tools or are a lot of special knowledge and tools required. I have done a head gasket on my M3 to kinda judge my technical ability.
Any insight would be greatly appreciated.
