talk to level 10 as well. they do *great* work on subarus, dsm's, anything automatic.
my GUESS is you roasted your converter due to extremely HIGH trans fluid temps and boiled the fluid.
Doing constant brake stands and launches under boost without a transmission cooler WILL do that.
I had a *built* '78 Trans Am with a 400 cube big block that *ATE* built automatic transmissions with manual valve bodies for lunch, THEN i finally realized my error and threw in a transmission cooler. *hundreds* of passes and a year later and it's still running the same as the day the rebuilt setup went in. After talking with the trans shop that does my rebuilds he was saying it's *VERY* common for cars with high HP/TQ that stall up the convertor off the line and launch to munch the converters and transmissions because they're boiling the fluid.
IF i had an autostick the FIRST mod i would do is a trans cooler. I put one on the tow vehicle after that munched a transmission towing the 30 foot enclosed trailer to the west coast, now 25,000 miles and MANY long distance tows with a fully loaded trailer later the transmission does *not* slip when we're towing the trailer fully loaded like it used to. so in *my* experiance any way, they DO work.
