Transmission Problems

Alright this is kind of hard to explain so bear with me. I have a rebuilt tranny (auto) that was rebuilt about 9 months ago. It has a one year warranty on it and there is a minor problem I am noticing. When I am at cruising speeds and have the pedal down in a "frozen place" if you will it starts to kind of deaccelerate. It will go down about 4mph or so and then quick downshift and and catch back up and then repeat itself over and over agian. It also is leaking some transmission oil that I can see when I have had it parked in one spot for a while. What do you think is causing this? Any help is greately appreciated. And by the way I checked the FAQ and didn't see anything on this (mabye I overlooked something).

Sorry I can't help with an answer except. Take that sucker back and make them back their warranty. With it acting like you mention yet alone a leak, that would be what I would do. Or as some might say, "Time to do a 5 speed swap".

Thats the only advise I can offer. Good Luck in getting it right.

I would love a 5 speed swap. Do you think there would be any chance of that if I took it back to them if it was really screwed up?

I would seriously doubt they would do a swap for you in place of a warranty repair. I don't know who did the work or if they even do swaps. If they do maybe they would offer you a discount to do it.

All I know is on our previous car "Prelude" our auto when out and I searched on doing a swap and it got pretty involved yet alone finding all the parts to do the job.

I just put a used tranny in it then sold it, (Got the GT 5sp :) ) because it was going to happen again. Their triptronic transmissions are horrable!

This is what was involved with the "Honduh" 5 speed swap FYI.

Being new to the Mitsubishi 3000 GT scean (3 weeks) someone else will have to jump in for more info for a swap. Or it's in the FAQ ;)

Well, my minivan, and most other cars with cruise control will slow down and speed up around areas with even slight inclines. Now about the downshifting, maybe it's not that, but your overdrive is messing up???? The leaking fluid part doesn't sound good at all, and it'll usually only get worse down the line. I'd get it looked at man.
