my ax15 in my TJ is having all kinds of fun issues. the synchros have been going for a long time, and last time out it got stuck in 2 gears at once (you let off the clutch and it binds and the motor dies).

i'm contemplating a few options. one of them is ditching the AX15 for an aw4 swap. i located one with the computer and all the wiring (it's still in a jeep) but i had a few questions for the fabricators out there.

1. i have an adapter to go from my ax15 to the D300. are the output splines different and is the shaft the same size on the AW4 vs the AX15?

2. how bad is the wiring to get it to run?

3. what shifter did you use for the auto trans? stock jeep or did you do one from summit or something?

Thanks guys! i know my driveshafts will have to be changed, but that's no big deal. i've done that before.

It sounds to me liek agreat excuse to swap out that 4.SLOW and put a GM V-8 and Trans in that beast. If you really want to swap the AW4 in see Milkman's write up on HRJA. He said it was the best thing he ever did to his TJ.

If your gonna do the AW4, I'd only consider it if you setup up for normal shifting with an over-ride function allowing for full manual control with the flip of a switch. That way the drawbacks of each function can be dealt with easily, AND if you go with deeper gear reduction you can wire the brake light switch to put the tranny in OD whenever the pedal is pushed to reduce the automatic trans driving through the brakes issue.

It actually has a fresh 4.5 stroker that runs fine. So I'm not in a huge hurry to swap it out. I've contemplated doing a 360 out of a ram with an auto trans though. Chevy stuff is also cool and could be a consideration, but really isn't needed. The stroker gets it done fine.

Hmmmmmm I wasn't thinking about the 1st gear ratio in the aw4... I'm 4.88s and a 4:1 right now...

I didnt realize it had a stroker, sweet. I have an extra NV4500 for sale, if you want real 5 speed beef ;)

If you decide to ask a more realistic price we can talk :-)

the spline count depends on the year the aw4 is out of. i think it was the 91 and down had the 21 spline output and the 92 and up had the 23 spline out put. not 100% though. i'm not on my computer to check my favorites and don't remember the site off hand. shaft is the same size as long as the output of your aw4 is a 23 spline like your ax15.

no clue on the wiring, my jeep came with the aw4.

gonecheenin, that's a pretty slick idea to fix the brake issue with deep gears.

Make me a realistic offer.

Novak has good info on that issue.

The AW4 being solenoid shifted opens up alot of fancy possibilities!

All you should need is a relay installed in the right spot to re-route power to the 4th gear solenoid when the brake lights are activated.
To give you an idea on the signifigance of that - Ryan's current setup with an AW4 trans swapped in and running in 1st gear comes out to a 54:1 ratio the brakes have to over come when stopping - with the same setup & the trans now in OD the brakes only have to over come a 15:1 ratio, which is lower than most stock 4x4's are from the factory.

I need to see how much the conversion to make it 4x4 would be and how to make it work with my d300... I think 6dof paid 1400 bucks for his brand new 4500... New in the box from aa...

I'm wondering if a 3550 would be a more economical and easy route than the auto or 4500...

For as easy as you are on your rigs, all the more an AX15 costs, as well as they hold up in most applications, & all the more time it'd take you to swap another one in - I'd just throw in a good condition AX15 with the right synthetic lube & keep motoring.

From the issues your having - I'd say the wrong trans lube & shift rod/seperator plate wear is your culprits, not a lack of strength for what your doing with it.

i wonder how the wiring would work if you were using an RA designs shifter with a tc lock up? would you just wire in the relay before the wires for the RA shifter?

only downfall i see is trying to stop on a steep decline.

sorry for the hijack this is just on my list of things that need done

There's also a 6 speed on bay for 700... That has like a 4.5 first gear...

Advance Adapters Product# 50-0205 is the part to convert a GM 2wd or 4wd NV4500 trans to a Jeep Dana 300.

so i'm 600 into an adapter for the 300 (will that work flipped?), plus an input for the 300 (unless it comes in that kit) plus 275 into the adapter to connect it to the 4.0... plus whatever it costs me to buy the Trans, driveshafts need retubed or shortened...

that's really what's stopping me from that. i'd be looking over 2k to do it. it'd be neat, but i think i could probably get a V8 into it for close to that...


i'm leaning 3550 or 6 speed... or an AW4 but probably not at this point...

I have a nv 3550 for sale. I sent you a pm with more about it.

I did the AW4 flipped D300 in my YJ with the RADesigns shifter. I can turn compression braking off. Lots of fun stuff. I'm running it with just the RADesigns shifter only. No trans computer. I'm at work posting on my cell so I'll try to get on the puter at home and give a detailed response. And yea I used the same AX15 - D300 adapter with my AW4
