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.

Sounds like a sticky solenoid in the valve body on the tranny.

I absolutely hate automatic transmissions. There are literally thousands of parts in them and a whole list of things that could be wrong.
I would agree with it being a sticky solenoid like previously stated. It seems most likely. In any case, unless you are confident in your ability to repair such a delicate part, I'd either call a transmission shop to check it out or replace the transmission.
I just replaced the transmission in my Civic, which had no reverse or D4. Had to start in D1, then D2 and D3 would only work if it was warmed up. Metal shavings were caked on the magnetic drain plug and the fluid looked as dark as oil.
You checked your fluid level. Is the fluid clearish red or is it brown/black and not so clear?

you have not got one....you ought to take the bolts out of the tranny to empty it.....i be attentive to it sucks. Blame GM. I only loosen the nook one (do no longer remember which nook) and slowly loosen the different to tilt the pan in the nook course. that's in the adventure that your on point floor. If no longer discover the place your lowest element is....On ramps it will be the returned ones. this is messy even though it worked for me

Correct all vacuum hose leaks under the hood . This may solve the problem.
