Yeah I'm running a 3500 stall. No problems at all and performance is top notch I have a problem right now with my front wheels locking up if the car moves backwards, both with the tranny in reverse and when it's in neutral. I'm not sure what's causing this yet or if it's even a tranny-related issue, but do I know it's not related to my torque converter in any way.

The reason why some 2GNT/Avenger/Seabring A604s go into limp-home mode when the torque converter stall speed is over ~2900, while others do not, is because of differences in the TCM software. There are two major versions of the software used in our TCMs. Most 1995 and 1996 models have the "early" version and 1997 through 1999 models have the "late" version. Updating the computer's software (flash ROM) from the early version to the late version may be possible, but some TCMs refuse to take the update for some reason It's also virtually impossible to find anyone who knows about this shit, let alone have the software/scantool/knowledge to perform the update. The late version of the software code was released in May of 1996 and was calibrated specifically to reduce frequency of limp-home occurrences.

I highly recommend selecting a torque converter stall-speed of 3000 or less if you have a street-car for it drivability, reliability, and performance features. Anything over 3000 would be a custom job anyway and modifying the stock torque converter is a bad idea at that level.

All-in-all, I think the 1997+ A604s perform well and are quite reliable. DSM didn't use a sufficient ATX cooler on any model 2GNT, so get one!

I'll stop typing now... I can't even remember what this thread is about now.
