2004 5.3 vortec/swap
 
I have an opportunity to swap to a 5.3 vortec-4l60e tranny and t case (not sure which one it is but i think should be pretty good) the donor vehicle is a 2004 avalanche.
My jeep don't need this big of an upgrade, but my families goal for our jeep is bigger axles and lockers with 37s...
So i guess my question is, would a 4.0 be ok or should i do the v8 swap while i have a chance to get the 5.3 for really cheap?
And if swapping to the 5.3, how difficult is it, or what would a shop charge to do something like that (ballpark). Any information on this will be very grateful, thanks.

The 4.0, especially if geared right, should do fine for most of what you'll need, even up to a 37" tire.

That said, there's no replacement for displacement and if you can get the 5.3 cheap, I say go for it.

You'll need adapters (most likely that tranny to the t-case you already have) from novak:
Adapting the 4L60E Transmission to the Jeep NP / NVG Transfer Cases

You'll also need the computer connector from Howell (or similar) for the harness.

Then you'll need cooling, motor mounts, etc.etc. It's a big project but it's been done thousands of times and is well documented, so shouldn't be an issue.

If you have the time and money go for it I did the same swap to mine and I've never been happier with my jeep I got a whole lot more power and way better mpg.

You did the 5.3? If so minus the engine and tranny, how much was the rest of the needed parts, and roughly how long did it take?

You need a transmission to t-case,I got it From advance adapters also the motor mounts. I did the sleep yoke eliminator at the same time, also from advance adapters. When I got my engine and tranny it came with the wiring harness and computer so i sent it to Novak adapters and they fixed it to fit my yj. I only had to connect 7 wires. I got a shifter from advance adapters for the 4l60 e. also a radiator, an electric motor fan, but you can use the one that comes with the motor, an air filter and a few elbows for the air filter, I got the gas lines and fittings from speedway motors, I had to replace all the gauges in dash board, and send it to a friend to do a custom made muffler with a flow master, then a year later I broke my Dana 35 so I replaced it with a ford 8.8, but I knew this would happen so I was saving for it. It took me about 3 months to finish it by my self, but I would have done in less time if I didn't run out of money. I don't regret doing this because I had a lot of fun during the process. And the satisfaction with the results is priceless.
