I feels like you are actually driving over a small speed bump while cruising down the road. This problem started a few years back so I dropped the tranny pan, changed the filter,added a drain plug and switched over to Mobil 1 synthetic ATF. Guess what- problem went away immediately. But now everytime the oil is changed it comes back. So to fix it, I drain out about 4 qts of atf and reservice the tranny. But at 6.50 a quart, this is getting friggin ridiculous!!!!! What in the hell is the connection between a damn oil change and the t/c bump??? And why does 4 qts of new fluid make the problem go away?? I need some serious brainstorming on this one. I wouldnt believe this either if it wasnt happening to me.
