Need ATX help

[shodup]

I now own a white 94' ATX that had the tranny rebuilt about 3k miles ago it wasn't driven much during the 3k and it was fine.

I bought it and needed to bring it on the highway for the first time and it completely went off in 3rd and 4th gear after about 20 minutes.

The tranny overheated while it was literally kicking me out of 3rd and 4th gear. Brought it back to the tranny place because its covered under warrenty and they pulled codes and tey read the O2 sensors were bad and caused it.

Well i changed the sensors and MAF because it previously pulled the MAF code but both did absolutely nothing except fix my idle problem but once the tranny heats up it starts shifting hard and wont shift into 3rd or 4th gear it tries ut doesnt lock up BUT when its cooled off it workes just fine.

I think it might be the intercooler for the tranny but im not sure any help is really appreaciated thanks.

Sounds kindof like a valve is sticking in the transmission. I'm not famliar with them, do the SHOs use the same ATX as the run-o-the-mill Tauruses? Either way, I'd get a second opinion.

No they don't...the two tranny's are vastly different.

It sounds like once the tranny gets to normal operating temps that it begins to malfunction. You need to take it back to the shop, it is not right.

In a properly working ATX you should be able to really heat the thing up, and it will still function in all the gears...
