Thought they were the same size?

Not really worried about it, plenty of supercharged 4x4 pushing 350+.

Having the torque converter lock and unlock manually is a BAD idea. The only people that really need them are the diesel crowd and the drag racers. The converter locks up at 30-40 mph anyways and stays locked up until you either A. Tap the breaks. B. slow down. There is absolutely no reason for this at all unless you are doing trailer pull competition or getting ready to run a 10.68 in a 1/4 mile. It is way better on gas milage, and the engineers design them to 1. Last for a long time, and 2. Allow for the maximum gas milage possible out of the vehicle. Don't mess with the tranny! Trust me, I was a trans tech for years for GM and there where very limited thing that you needed to do on a 4l60e to make it last longer and a little more efficient.

Diesel fapper!!-j/k. When the trans shifts with the converter locked under load, it is extremely hard on internals, shafts mostly. Coming from a diesel racing background I've seen first hand what happens to internals when you lock the converter. And those were sometimes even built trans with billet shafts. Most of the time is was dingus with a programmer and a stock trans. Those go boom in a hurry.

It's the shock loads that are the worry, not the horsepower. You can generate a lot of shock load with even a stock 4 banger. The hydrostatic coupling makes a huge difference in protecting from that. I'm not saying you will break it, I'm just saying it's a consideration. That's why the shaft in the manual version is massive by comparison.

hmm. You guys are bringing up some dam good points.

I'm still really tempted to try it, just for controlling descent speed (of course not shifting through gear when locked).

There are many mods that are fine if used with a full understanding of the unintended consequences and a little maturity.

yup. I never really intended to shift through gears with it locked up, but never gave it thought that it would hurt it.
