AODE slips???

This is weird. I have a 95 GT. When I gun it and the car is cold, it runs like a champ (tires sqeal). After the car heats-up (i.e. drive at high speeds for 10 or more minutes) and I stop and then gun it, my car DOESN'T MOVE AT ALL (it slips like it is in neutral). If I gradually press the gas it does't slip at all. When I am at high speed and I gun it (down shift), it just slips until I let off the gas and gradually press the accelerator (it catches). So what do I do, I swap out transmissions and install a edge stall converter. When I pulled the old transmission, I notice that IT was used (it had "core" on it). After replacing the tranny, my car still does the same thing. I went ahead and installed a JET Chip. No change to the slipping. Is this a PCM problem? Something electronic going on here? Is it the rear end/clutch packs? Need some thoughts here.

Your transmission is overheating. Since you've had the same problem with two transmissions, I'd wager that the coolant circulation lines from the transmission to the cooler are clogged, causing the tranny to overheat.

Flush these lines and hope that you haven't damaged the new transmission and converter. Good luck.

I forgot to mention that I installed a transmission cooler with the new transmission. There was no change. Could the lines still be the problem?

Also, I had the older transmission serviced which included the lines being flushed (I called to verify) before swapping.

Update on AODE probs

I am still troubleshooting this problem. I have taken to the dealer. They said it was neutraling out, there were no codes, and I needed a new tranny. Didn't buy that one. Took it to a reputable tranny guy here. He just drove it and said I needed a new tranny. This is the 3rd tranny with only 77k on the car. It has to be something else. So, I replaced the TPS and the Neutral Safety Switch (A.K.A MLPS). I had the tranny serviced again and added the B&M Trick Shift fluid. Still no change. I got another EEC on ebay for $55 w/shipping. I am waiting for that to show up. If the EEC doesn't work, I will go with a new speed sensor. Any other suggestings would be much appreciated. Thanks

more updates

Here is a quick update. In the last month, I have changed the TPS, Neutral Safety switch, and the EEC. No change. I have learned one thing though. When it starts neutraling out at WOT (only after the car heats up this happens--see below), I can manually put it in "first" and it won't neurtral out. It runs like a champ. That has to mean something. Someone help me out.

Thanks

Thanks, but Mine doesn't hesitate. When its cold, it grabs just like it is supposed to. When it is hot, its like WOT in neutral until I completely let off the gas to catch. Just after neutraling out, I can drop it to first and it will grab perfect at WOT. Again, I can put it back in Drive and it will neutral out. Other than this problem, the car runs great and has plenty of power; low and top end.
