NSG370 swap from 3.6 JK to 4.0 TJ?

[Justus]

Hi all, I am desperately trying to find info regarding changing my 6 speed. I currently have a 97 that previous owner put NSG370 and turbo into, I have lost 3rd and 4th gears only so have a replacement box ready to have swapped.
The newer one is from a JK 3.6lt V6 with only 10,000 kms use and I have read that apparently the TJ 05 and 06 were different.

Any info would be greatly appreciated as I live in remote ( in bush ) and having to transport mine on truck to a town to have done.

Thank You

"The 370 is factory compatible with the Jeep / AMC 4.0L I6 engine, when equipped with the right bellhousing. It is also compatible with the 3.8L V6 when equipped with its matching bellhousing."

Not entirely sure about the 3.6, but I imagine it's the same thing.

The TJ model has a different bell housing bolt pattern than the JK.

To replace the bell housing requires you replace the whole front case half, which requires a complete tear down for the most part.

Thanks guys. Fingers crossed maybe the existing one was from a newer but I won't get my hopes up. I will try get to car this afternoon and look at bolt pattern

It appears housing is completely different, Unlucky me once again.... Guess I bite bullet and look at a LS1 then now.. Any ideas if a T56 box will go in at all?
