Rebuild or leave trans?

Converter ballooning only happens with pretty high horsepower if I understand it right. I'm no torque converter guru so the best I can explain it is the torque converter swells up and pushes forward hard enough to take out the thrust bearing in the engine.

One question, when you pulled the pan to install the shift kit how much "mud" and metal flakes did it have in the bottom of the pan? If it wasn't a lot chances are it'll last a long time. If it had mud 1/8" or more deep and metallic flakes things are worn bad.

That's good to know that's it's not really much of a concern for the motor, so I won't worry about any type of failure that will damage the engine.

And when I took the pan off there was only a little bit of "mud" in the pan, really just a film, that wiped off with my finger. Not even close to 1/8" too thin to even measure, and I didn't notice any metal flakes either. When I took the pan off after running it for a while to fix a leak, it was still pretty much clean. So that's a good sign.
