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:
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.
