"Can you?"

Yes you can but it takes money.;)

You can put what ever tranny you want in it if you have the resources and all the parts to make it happen.


What 4speed are you wanting to put in it?

rosefour 02-10-2009 03:21 PM

I want to put a 350 in my 97 tj wrangler. I researched some and was told i needed to get a AX15 tranny. My question is does it matter what year it is and what jeep model it comes out of??? I know alot of folks have done this swap so i hope someone can help me. Local junk yard has a few I just want to get the right one. Thanks

distortedtj 02-10-2009 06:56 PM

Who told you that???

You can get adapters for the AX-15 to a GM350 motor but I wouldn't recommend it.

If your swapping in a 350 go with something stronger. SM465, 4L60 ...Some thing that will last behind that motor.

Very nice thread. I've linked it in the TJ FAQ sticky at the top of the TJ Forum. Great information for the masses.

wolfen 11-24-2009 09:24 PM

Thank you I emailed Chrysler for my info they sent me the forward gear ratios, and differentials, but not the reverse or the model of the trans :)

bally12 02-09-2010 11:42 PM

hi all,
just wondering if the ax-15 will bolt up to the my 2000 tj? my gearbox (nv3550 i believe) has shit its synchros and i can get an ax-15 for real cheap. fingers are crossed for a yes on this one........

TheTJRod 02-10-2010 12:17 AM

The AX15 should bolt right onto the I6 motor. As it is the exact same one that is bolted to the NV3550

bally12 02-10-2010 03:39 AM

Im hoping this is the case. Im strapped for cash atm and don't feel like blowing my money on something that is pointless.

bally12 02-11-2010 07:16 PM

has anyone upgraded from the ax-15 to the nv3550? If so did it bolt straight in?

titan 03-02-2010 01:54 PM

I have a 99 tj with an i6 and the 3 speed tranny and wouldn't mind putting in the 4 speed. Can I do that as a straight swap and do I have to do anything to the computer.

phantomofrussia 08-11-2010 08:55 AM

That is very useful info. thanks distorted!

Quick question though. What does the 10 spline input and 23 spline output mean?

I would bet that you would want to grab the computer and harnesses too. Though don't quote me on that

The 10 spline input refers to the input shaft of the transmission that mates to the engine.

Here is my NV3550 input shaft while doing a clutch replacement.

And the 23 spline output refers to the rear shaft that mates to the transfer case.

Here is an image of a AX15 output shaft I grabbed from Novak Conversions

And here is the input shaft of a trans-case

I think as long as its coming from a 4cly,same year cherokee you should be good. I want to say you may have to change the an input gear(can't recall the correct term atm, sorry) have you also looked on car-parts.com?

awsome info

Swap Question
 
I have a 99 with a 2.5L 3 speed Trans and was wondering if i could do a direct swap to the 4 speed trans....the 42rle? im sure i would have to change the computer too right? Is there a guide to doing this somewhere?

Thanks

Jerry Bransford 12-19-2010 09:20 AM

Trying to get the 100% computer controlled 42RLE 4-speed automatic working in a 2002 or older TJ would be like trying to get Android working on a dial-up telephone. :D

garyb 12-19-2010 10:13 AM

i guess that's a big now way then.......the only way to go to the 4spd trans would be a complete engine and trans swap to the 4L then huh???

thanks for your quick reply...

sandro 12-29-2010 09:26 PM

thanks ! I called the local jeep dealer today to ask what fluid to put in my tranny. I gave him the vin number and he told me I had an ax-5? I don't know the diff, but i believe you over him, he didn't sound very confident, and he put me on hold to ask someone else !
I have a 6cyl 4.0L 2001 wrangler sport 5 speed manual tranny. your info says the ax-5 was for 4cyl? anyhow, i trust you guys over them, so thanks for the info.

ax15's for the 6 cyclinders.
but both transmissions ask the same fluid GL-4 75w90
Redline MT-90 would be a good choice.

Ageless Stranger 12-29-2010 10:00 PM

Nice post Tim. Good information. :cool:

TexasT 12-29-2010 10:06 PM

Sandro
If you have a 2001 5 spd, you have the NV3550 transmission.

sandro 12-30-2010 06:18 AM

thanks texasT I'm guessing that's what it is based on the above info, so....it takes 75W-90 ,yes? But i should go buy MT 90 cause it's worth the extra $$, yes? I know im an idiot, thanks for everyones help
