I bought a '88 cutlass supreme FE3 automatic last year for 100 they said ididnt drive after they let it sit for a year well i got it running but noticed it didnt shift. iv been driving it round the block bout once a week to keep everything in chec and i went to check the trans fluid and it looks almost new but its pretty high on the dip stick anyone know if that could be the cause of the not shifting cause the car runs good at 130000 w/ the 2.8L engine. gonna try to suck the extra trans fluid out w/ a hose. but reply thankx.
