I have the vehicle listed above JKU with a 3.8 v6 and a manual transmission, (NSG370)

I found a manual transmission (NSG370), out of a 2014 Wrangler JKU with a 3.6 V6, with 50,000 on it.

Will the 2014 manual transmission bolt up to my 2007 3.8 engine?

Good afternoon,

Yes, the transmission will bolt up to your engine.

Make sure the clutch splines are the same for the clutch.

The newer bellhousing will not mate with the 3.8 engine.

Maybe. You have to see if the bellhousings mate up. The transmission for the smaller engine also may not be able to handle the torque and horsepower from the larger engine.
