Hello, its been awhile since i posted. The buick has been sitting while i was out of town for military training. Well im about done and would like to get back to the buick. When i left i was wondering if the TC or Trans was giving me problems. It seems to be slipping. This being my first time dealing with a performance car with an auto im lost. Is there a way to test the TC or the Trans for this? I would hate to drop alot of money on a trans if i didn't need one. When i go WOT the car does not want to move. I mean its moving it just does not want to accelerate. Rpms shoot up high then somthing seems to catch and then it goes. This seems to happen in all gears. I dont seem to notice it that much when im on the freeway and punch it. Well thats what im dealing with. Any help would be appreciated. Thanks again and if you need more info i will do my best to help.
