NSG370 6 speed in cj5?

Peej03 · 01-17-2011, 08:15 PM

Just wondering if anyone has done this or if its possible. I know people put 4.0 and AX15s in. Would a 4.0 and 6-speed fit right at home in a 83 cj5?

The NSG370 has a built in bellhouse and measures 23.5 total. A t176 (common later cj5 tranny) and bellhousing is around 19 inches. There is not a adapter to mate a NSG370 to a d20 or d300 so you would end up changing tcases as well, which would likely make things even longer. The NSG370 will bolt up to a 4.0I6. They make one that will bolt up to a 3.8L V6 also but its 1.3 inches longer. Since the bellhouse on it is part of the tranny dont think you could get it to mate up to anything else.

So maybe if you wanted to change not only the tranny, but the tcase and possibly the engine and the stretch the jeep a little it would fit. Does not seem worth it for a extra gear.....

Well the CJ5 Im looking at has a pretty rough drivetrain, so I was wondering if I could get a newer wrangler or cherokee drivetrain to replace it.

The benefits would be.. Not having to lock in the hubs in a mudhole, 4.0 fuel injected, 6-speed... Doesn't seem too bad of a deal even if it was a 5-speed.

Even with a 5 speed, like a ax15 or nv4500, its probally going to be to long. The 5 already has a tiny little driveshaft. You can find used orignal drivetrain parts that bolt in cheaper than moding to fit something else. The t176 and d300 is a great 4 speed combo and easy to rebuilt. Might be cheaper for you. If you do try to pack it in make sure you post up lots of pictures!!

Good luck!

I was just thinking the ax15. I thought I had read of that swap being done on here before. I may be wrong

Sell the Jeep and buy a car if its too much of a bother.

Plus, as anyone who actually wheels as compared to web wheeling knows, you lock the hubs in BEFORE you hit the mud hole.

Well I don't have the jeep yet, and the only car I'll ever own is a amc Javelin. Maybe a Geo metro. Jus cause.

Wheres the fun in trying to make it through a mudhole or snowdrift in 2wd? But I'd rather not wade through a foot of freezing mud and ice when I do get stuck. And in -40 degree weather when I go get my wheelin fix I'd rather not get out and lock the hubs.

Could also be because I'm only basing my hub experiences on my 77 Chevy work truck.

I'll just pretend I didn't read the web wheeling comment

There have been ax15 swaps done in to CJ7's here I have seen but not in 5's, again because of thier lenght.

Did you know that you can run in 2WD with your hubs locked? Your TJ does it all of the time.

As said before the problems with different drivelines in a CJ-5 are length.
Many transmissions can be adapted to a CJ-7 since it is 10" longer than a CJ-5.
CJ-5's never even came stock with an automatic transmission for this reason.

Good luck on trying to do the swap However I think that looking into stock CJ5 replacement transmissions would be a good idea and possibly save some money and headaches.

A member was putting an ax15 in a cj5 a couple of years ago but I don't think he finished his thread. As said the driveshaft will be very short. You can move the engine as far forward as it will go to get another inch or two.
Not saying it can't be done but it's not the easiest or best swap. I would get a cj7 if that's what you want to do.

Also the with the 4wd. You can leave the hubs locked and switch in and out of 4wd with the shifter on the fly.

Gotta love technical questions about a Jeep that isn't even owned yet. Planning a build is one thing. Daydreaming out loud is another. If you are serious about this, start researching parts availability of this transmission. You'll have to pioneer the swap since it appears few people if anyone have done it. As was said in the first post, the length of this drivetrain combination will make it impossible in a stock-wheelbase CJ5. The AX-15 has been done numerous times in CJ7's and CJ8's, I have one in my CJ8 and like it a lot, but I have an extra couple feet of wheelbase that your hypothetical CJ5 won't have. My CJ5 runs a T176, which is right at the limit for length. My rear driveshaft is only about 13" long and runs at a very steep angle.

When you stop daydreaming and start building, let us know how it's going.

Well I applied for the loan at 2 banks acouple of days ago to get the cj. So its not really day dreaming. I'm just so excited to get it I had questions brewing.

Yes I did. Just gives you a lower gear before putting it in 4wd right? unlocked my work truck cant get out of the shop. Locked it can go just about anywhere in town during the winter. And I have to put it in 4wd for dump runs.

I guess I'll just quit asking questions until I get approved.

13" !!! My CJ5 only has a 12" drive shaft with the t-177.

Just to show some CJ trannies wont fit,
here is a T4/T5/Dana300 vs the original T-150/Dana 20 in length:

Umm, no. Locking the hubs merely "locks" the front axle together with the front wheels. The front axles, differential, and driveshaft will then be turning if the vehicle is moving, but they aren't powered unless you engage 4wd in the transfer case. The gearing is the same in 2wd as 4wd high. The only time you get a lower gear in in 4wd low range.
