You likely get to keep TOD if you only replace the engine. The TOD works off of the transfer case which is married to the transmission. Having TOD without the stock transmission/transfer case is close to impossible to expect. You have to keep in mind that TOD is just Isuzu branding for an early traction control system. As far as a TH400 bolting up, I don't know. I have an intense personal hatred for automatics I do believe however that someone on this forum was looking into what would bolt up and doing a little more than talking about it so you might try searching a little more. Also, read this so you don't get your hopes up:

Still in fab process, but will update with photos as the progress continues.

Okay yeah I want to get a new tranny my current one is ehh at best. So if i go 4l60e or th400 and have the dana transfer case I should be able to keep TOD, that's good to know I mean it isnt the end of the world to lose it but it would be nice to have I always liked it since my trooper. I was researching and the 5.3 is the cheapest way to go for sure, I just have to get all the little stupid **** manifolds, wiring, etc. I would love to convert it to a manual but that would be too much for me right now. I'm gonna get in touch with the autopro guys from Maryland see what they say about the th cause I found a few for only 1200 new, the 4l is almost 1800 from gm.

I think there is something you're misreading. If you dont keep the stock transmission/transfer case, then you are going to lose TOD. With any other automatic or manual transmission and transfer case, you are going to be locked into either 2WD or 4WD. Thats it. And the 4WD is 50/50 front to rear power split with no adjustments. TOD lives in the stock transfer case, so a dana or any other case just doesnt have it.
