Hi all, I have a knackered 2007 NSG370 6-speed tranny in my JKU. It pops out of 1st gear every day, it grinds into second regularly....in short, the synchro is gone. It's expensive to crack the tranny open and repair, so I looked for a full replacement to compare price. I found a 2009 NSG370 on the local classifieds. It was taken from the jeep after driving it to a shop for complete hemi conversion, so there are less than 100 Kms on the tranny and clutch.
My question is, are there any major changes in driveline between 2007 and 2009 that would create an issue with a swap for the newer model tranny?
Thanks

 

Yes it is the same if it came from another wrangler (2007 and newer). Jeep TJ has a different bell housing for the 4.0L engine.

 

Great, thanks!

 

Great find! What did it cost? Just curious?

 

I'm curious as well, I'd really like to swap from my auto to a manual it drives me nuts not being able to shift.

 

I got the tranny, clutch assembly, throw out bearing, flywheel for $650 CDN. Great deal as the only mileage on it was from the dealer to the shop that did the hemi conversion. There's about 100kms on there total. The clutch is absolutely mint and the tranny has all the labels on there and looks like it just came off the shelf.
My regular maintenance shop is installing the unit next month for an estimated $480. All tolled I'm looking at about $1200 for a brand new tranny and clutch assembly. I'm super happy, as the whole job would be close to $3000 at the dealer.

 

I think switching from an auto to a manual is a bigger job than the simple switch out on my vehicle. You would need the Gauge cluster, hydraulic master and Slave clutch system and associated lines, the pedal assembly, and I'm sure there are wiring issues to the ECU as well. I'm no expert, but I'm thinking you're probably better off to trade your automatic rig for a manual one rather than put yourself through a nightmare retrofit. IMHO

 

X2....Not really worth doing.

 

I looked into the change over, hydraulic system is a one piece sealed system, which is easy to install, as is the clutch pedal. The only real problem is change out of the ECU which has to be rebuilt and programed to stop looking for all the old autotranny inputs, otherwise it's the same. Unfortunately I lost my lead on the planned manual tranny.
