Default Transmission is out again

I need to replace my transmission this would be my 4th one. I had one under warranty one out of pocket after that one went bad I got a RPM stage 6 and now that one is gone with less then 20000 miles on it. The car has 647 rwhp super charged. I'm so sick of this I can't stand it. No one knows why it happen and rpm has not been any help just told me I need to get a better one. I really don't want to give them any more money. Does anyone else have a place that I can get a new or rebuild trans for a 2001 auto. Thanks

What are you doing with it? Daily driver duty? Guessing with 650whp you are beating the crap out of it. What is failing? the clutches? Do you have a trans cooler? Need way more detail here.

I can't help ya with your problem, but if it makes you feel any better, I'm get'n ready to put a new one in mine and it'll probably cost 4x as much as your did.

Are you running a big stall? Do you have a cooler? I have a RPM level VI at about 550hp/Tq and beat the hell out of it but I needed a separate power cooler to keep it cool mounted under the headlight. From what I've heard heat is what kills these.

Sounds to me like something in the trans tune is fubar'd. These things just don't fail on the street 3x because you got on it a little.

647 rwhp. It lasted 20K miles. I wouldn't expect it to last much longer than that.

Being it's the 4th one, and that I don't recall lots of other folks saying a trans will only live 20k, I'm inclined to think something is amiss.

What was the failure mode of the other 3 transmissions? Do you have a way to monitor transmission temp?

You have something else going on. I would say it is the tune. No way you should be going through trannies like that

You can see it right in the DIC, mine ran hot 230* and climbing with a passive cooler mounted to the radiator so I put a powered fan one (B&M I think) under the headlight and now stays well under 200* 185* most of the time. You remove the brake duct and vent into the wheel well, it works great.
