Me and my dad swiched vettes for two weeks, his is a 88 with the 4+3 overdrive trannsmission. I noticed driving it back to school that when the overdrive first engages that there is a bad shake between 45-60 has anyone else experienced this, I know it didn't do this before.

Possible transmission slippage or bogging because of the low RPM's? Seems when the RPM's are up, OD works fine... hmm.... is this common on these cars? Shift points to low?
Thats what I was thinking.. Possible Trans slipage.. probably the clutch pack or packs in the overdrive section of the trans.. I know when my trans was taking a dump in my 95.. that for expample starting off from a stop it would shake/vibrate real bad.. If was from the clutch plates slipping and gripping.. eventually I could just lay into the throttle a bit and feel it slip.. No problems since last overhaul.. And with the rep. that the 4+3 has most likely it's taking a dump on you..
