GREAT point! TOD would be disabled if I understand correctly. The VX or Trooper 5Speed computer is required to run it. In that case, wouldn't you be forced to go 5 speed anyway? Does the 4L30e receive input from the engine's computer?

Wait... I don't know WHAT I was thinking...
Scratch that last post.
The engine's computer doesn't control the TOD...
But, it does control the transmission, does it not? That's why there's two versions... Manual and Auto.

FWIW, 5-speed Troopers do not have the TOD transfer case.Originally Posted by SilverBullet75
In any case if I were you guys I would look at a different tranny than the 4L30E...
95 Trooper with a buncha stuff nobody here cares about...

I know that it is a bit off topic, but what type of transfer case do they use?

96 Eclipse Spyder GSX (already turbo, AWD swap)
93 Eagle Summit AWD (4G63 turbo swaps)

I think the 98+ 5-speed Troopers use an Aisin, don't recall the number.

What does it mean? Did it have a diff for "AWD mode"?

My Rodeo doesn't have the 4L30E in it, mine has the better Aisin auto used in the 04 250hp Direct Injection Rodeo/Axioms. So I don't think i'll have any issues with it since it will only be about 50hp more than what the DI Rodeos came with.

Well after chatting with some LS4 guys, they recommended I go ahead and use the GM 5.3L truck engine along with the matching tranny. Mainly because it would simplify the wiring greatly by being able to control the engine and trans from the single GM ECU instead of using a standalone system, it would cost quite a bit more and would require custom programming going that route. I was thinking maybe I could just use my Isuzu ECU to control the tranny alone and using the GM one to control the engine functions, but it seems like it's more complicated than to make everything work correctly.
So i'm thinking i'll just go the truck 5.3 route since it would be pretty easy for me since my Rodeo is only 2wd, the main thing i'd need is a custom length driveshaft and mounts to make this tranny work in my rig with the stock GM ECU.
P.S. The LH6 GM 5.3 V8 has an aluminum block, not iron compared to the LY5.
