Ok guys, i just got my automatic transmission rebuilt exactly one year two weeks ago (just missed the one year warranty), and today I was driving normally to my friends house picking him up to go to work. I pull in his driveway, throw it in park and sit there with the engine running. Im sitting for a few minutes and decide to give a quick little rev, and it felt very resistant. So I freak out, and rev it again and it wont rev over 2 grand! I put it in drive, and it has this crazy hesitant feeling, like similar to if the parking brake was pulled, I put it in neutral, give it a rev, and it rolls forward a tad, still feeling hesitant, not going over 2k! I put it in reverse, same weird feeling! No SES light, engine sounds fine, good oil pressure, starts up fine. Is this a transmission problem or what, I can't figure it out. Any ideas?

idk sounds like the computer or something to me

If the car is in neutral/park and the car still doesn't rev over 2000rpm, then it's very unlikely that it's a transmission problem. Is the car missing? Shaking? Any noises?

+1 definitely not a transmission problem. sounds kinda like a loose plug wire, or pcm problem. maybe even a vacuum leak (less likely from the way you describe it)

stock converter?

406malibu

if it does it in neutral and park, it shouldn't be the converter.

I dont know i this is true in all gm cars, my 99 is a m6 so I cannot test it in my car, but I know that most sedans gm makes the car has a different rev limit setting for park and neutral. That is there for you guys who like to rev the He$% out of them without any load on the engine. I believe it is around 2000 rpm. As far as it being hesitant I dont know. Does it rev above 2000 when driving down the road?

my old v6 camaro did that, but it was at 4k doubt they put it that low on a ls1 car. but maybe (im in a m6 car too, so cant testify either way on that one)

My A4 will rev above 2K when in neutral and park, stock tranny as far as I know.

Yes it does, i can hit the 6,200rpm limiter

im guessing its something to do with the bands inside the tranny! i think it is a tranny problem. like if u keep it in 1st gear is it still hesitant?

406malibu

but why would it be doing that if its in neutral?

hasenbonkers

It wont drive at all, wont go anywhere!

definitely get it checked out by the same mechanics that did the work before, sometimes they will have a warranty to back their work. and they will be able to tell you if its a transmission related problem or not. good luck

Could be trying to be in two gears at once, that will lock it up. Something seriously wrong with the valve body might do it. That would explain why there is essentially no neutral and no go either.

In your first post you didn't say it wouldn't go anywhere. Unless I misread somewhere. That sounds like a transmission problem to me.

Ya sounds like the trans is in between 2 gears causing it to not go anywhere and also wont allow the car to move much. Sounds like a trans porblem to me..

idk much about tranmissions but when my car did this not long ago some dumbass before me sparayed crap all over the MAF and it wouldnt go over 2k rpm for nothing replaced it with a new MAF and the problem was fixed
