You are correct, I should have said "factory" upgrades.

But then those upgrades would mean that it was a 4L65e and not a 4L60e...key word is "5pinion"...

sorry to bring up an old thread

My question is, will the V8 LS bellhousing bolt up to the Hummer H3 4L60E? And, is it an upgradable unit to support V8 HP?

So you thought it was a good idea to dig up a SIX YEAR OLD + Thread to ask a questions??????????????????? READ: Old Threads/'Necro-Bumping'

Alphas (V8s) use the same Trans as the I5s. I think you need to use an H3 Bell Housing, you will need a Torx 50 Plus bit, and you will have to use the H3 Trans Pan.
