I have a 1996 Chevy Lumina LS 3.4L DOHC (86,000 miles) with a four speed automatic i think. With the shift selector set in D1 and it will go. I move it up to D2, Drive, and Overdrive. It is just like it goes into neutral and revs up. High RPMS 4000-4500 or so. Once it gets up to 4000-4500 rpms it shifts into the gears. There is no partial engagement at all, until the car slows down and it downshifts back into 1st. This problem appeared suddenly, with no partial slipping, shuddering, etc., but the car just had a new engine from a 97 lumina euro 3.4L put in it. The fluid level is correct. Could this be a problem with the modulator valve or something else? Or, what other things are likely suspects? Thanks for any ideas! The tranny was fine in the other engine, but now its not all of the sudden.
