I'm running an American Muscle tune and I've noticed a hell of a difference in driveability. But what I'm curious about is the increased pressure shifts it keeps throwing at me. Its awesome since it makes the car scratch 2nd and 3rd gear. But I wonder, is it causing damage to the transmission at the same time? I tried searching for the answer to my question in the search area but didn't have any luck.

It wont damage the tranny until you get 450rwhp.

Will this apply even if I use a high stall aftermarket torque converter?

MexGT

Yep, nothing to worry about.

So, what will be harmed by the upshifts when I reach a point of ~450rwhp?

I would like to know also since i have more than 450 to the wheels and have done nothing to the trans

I've tried searching on the forums, as well as the internet pretty hard. And nothing seems to match my search quiery. I'd really not any of us to be the first to find out.

Here's something to consider,

Especially if you read near the end of the article.

i hope my trans holds up i think my whipple is much harder on the trans then a centri supercharger especially launching

mine seems to be holding up just fine with 480hp and i abuse it often but i only have 2000 miles with the supercharger
