I have a 89 Z24 Convertible. I just recently got my Z24 after my first one was wrecked several years ago. I noticed that at 70mph its pushing 4000 RPM's. Is this normal or is there something that can be done to help lower the RPM's. I realize that back in 1989 the speed limits were a lot lower but 4000 RPM's seems high.
Is the convertor locking up? Check to see if the square blue plug on the radiator side of the trans is plugged in. Doug in P.R.
