So what's my problem? I ran a 3500 stall with LT/ORY, no internal mods for about 6 months with no tune or shift kit. Installed a cam, sent the PCM out for tuning, and the same day I put the PCM back in, fried 2nd gear. Got 23,000 on the clock. Some aren't as lucky as others.

 

thats kinda what happened to me. Not all are as fortunate as others

 

Maybe it didn't like your tune, maybe it over heated. I would say its a good idea to get a tune right away with a converter and I wouldn't trust a tune by mail. Dyno tune is the way to go so they can see exactly how your car is reacting to the modifications. Also did you have a tranny cooler or a trans temp gage? On a rare event my tranny will start to heat up. I never let it run over 180. I have the largest cooler ls1speed sells so it usually stays around 160. Could be a lot of things incuding bad luck. I'm not saying its 100% that your tranny or rear end will hold up, I'm just saying it can and the more things you do to prevent it from breaking the better chances you have. I think the #1 thing to avoid is wide open throttle down shifts for the tranny. For the rear end the best you can do is a girdle and susspension mods to prevent wheel hop. At least those are some of the things that have worked for me so far. I know its just a matter of time before they go but I'd rather it happen later than sooner.

Just noticed you have a cooler, guess it could be the bad luck thing.

 

Every single time, without fail, something goes wrong after a mod. E V E R Y time. It's just **** flavored icing on the cake I guess. I have the worst luck in the world working on my own car. Now if it's somebody else's car...

I suppose it could have been the tune. I had torque management completely removed. It's possible, especially the way I was getting on it the first day, that I toasted the tranny because of that.

 

Congrats on the 11 man. I should be seeing 11's soon as well.

 

Yeah, I'm very easy on it on the street but I usually do one wot blast each time I take it for a drive, which is about three times a week. Otherwise I never even go 50% throttle.

Thanks and good luck.
