Had the car for alil over a month. Its an all stock 87 aerocoupe, ive put a few k onit the tine ive had it. But i noticed tonight that when startinh from a stop in OD. i feel the shift to 2nd thne i feel it shift to 3rd then i feel it shift to 4th. But i dont feel a 5th type shift (lock up)if im cruising in 4th and get onit itll kock down to 3rd with no probs then shift back into OD but i dpnt feel lock up. With my 92 corvette its a noticable lock up on the 700r4. I know the OD on the ss is working bc if i down shift to 3rd the rpms go up. But im only feeling shift to 2,shift to 3 then shift to 4. Is this normal?
