Man I have been having so many problems with my transmisson this past year I traded a builder friend of mine that works at American Transmisson a snowmobile worth about $500 bucks to rebuild it. It has failed 4 times this year from him rebuilding it. He blames it upon abuse. No hard parts have ever failed. Car only runs 12.9 in the 1/4. He will not cover it this time around.

* The most recent failure has been after installing my Fuddle 3000 stall. The trans isnt actualy gone yet. It shifts fine when cold, but when hot it has a really soft and slippy 2-3 shift. Yes I have a cooler and a deeper pan. I think it needs a rebuild? I did drive the car with the new stall and with out the trans cooler for about 4 days. Could have this have overheated the fluid? Could maybe changing the fluid fix this?

 

Well yesterday I tried changing the fluild to some good stuff, new filter and went back to the EPC solinoid. No change Bangs the 2-3 limiter a few times before the shift. My season this year with my car is now over
It sucks. I have spent a lot of money on this trans this year. One thing I found out was after driving the car with the vacuum mod then going back to the EPC,the vacuum mod gives a lightning fast downshift, good for roll racing.
( Im not a fan of roll racing, but lots of people try to race me from a roll)

 

This sounds like the 3-4 clutches are on their way out. Abuse? Sounds like an excuse from someone who doesn't know what they're doing. We have 4L60E's in the 10's....Front wheels a foot off the ground...and pulling 1.4X 60 Ft. times. Don't believe the "abuse" thing.
