Advance Adapter SYE Install
Why do we lift our Jeeps? More than likely its for the same reasons. Jeeps where not bought to have tiny tires and wheels on them. After you lift a Jeep you raise the body higher off the wheel giving you more room to stuff bigger tires under the fenders not only for higher ground clearance, but as well the look they provide.
After you install your 3 or 4-inch lift or even larger you will notice when you accelerate and decelerate there is a slight vibration coming from your rear end. What is it? Its your driveline vibrating from the extreme angle you've put it in lifting your Jeep. You look at your driveline and it doesn't look to be very extreme. In your mind it isn't, but to your drivetrain anything over a couple degrees from the rear end to your transfercase is extreme.
There are a number of things you can do to correct this small but possibly damaging to your U-joints and other drivetrain sections.
Jeep 231 Transfercase and SYE leak fix
On my last trip down to Tillamook state forest in Oregon, climbing up a rocky, muddy hill I was bouncing around pretty good and wacked my rear diff a few times. I got out and noticed what appeared to be some red fluid. I shrugged my shoulders and figured it was either the guy in front of me or I must have a small leak. Needless to say after getting out of what I was in and parked at the top of the trail I smelt burning Transfercase fluid. Looked under my Jeep and sure enough I was leaking. I feared the worst. Oh, NO we are going to loose the Transfercase on the trail. I was really worried since its never leaked before so of course I was a bit excited.
One of the guys with me suggested that possibly my vent was clogged and blew free or I was leaking out from the rubber washer behind the yoke. At first I thought he was totally nuts and wouldn't accept that answer. Reached the top of the trail head and after a while we ended up at the staging area. I barrowed some Transfercase fluid and make sure it was topped off. Drove my Jeep over to a friends house for the evening before returning home the next day. I was to address my leak as soon as I got home.
Needless to say there wasn't a leak anymore and hey it must of been a fluke? WRONG, a month later I was doing some playing at work and climbing a hill or two and when I got back home there was a puddle of what looked like Transfercase fluid under my Jeep. Ive determined in my mind it must be when the Jeep is climbing, which puts pressure on the rubber star washer allowing the leak. Ok, this is it, Im mad. Im going to figure this out yet. I did some looking at below is what I found out. Needless to say. I was wrong and the little rubber star washer was the bad person.

42RE Shifting Solutions
The Jeep Grand Cherokee started using the 42RE transmission in 1993 1/2 models with the 4.0L engine. The "4" stands for 4-speed, "2" is for torque capacity, "R" is for rear-wheel drive, and "E" is for electronically controlled.
This article explains how the tranmission operates and how to diagnose problems.

Advance Adapter SYE Install
Whenever you lift a Jeep TJ above 2" (and sometimes even just 2"), your drive line will be off enough to cause what is known as drive line vibrations or "vibes" for short. Because of this, most lift kits will include a transfer case skid plate lowering kit to help restore your drive lines back to or at least closer to stock. For the most part, this will do the trick but then you have to ask yourself, do I really want to lower the very part of my Jeep that I just spent a boat load of money to raise up? Yes, there are other ways you can kind of get around this like installing a 1" motor mount lift and/or lowering your transfer case skid plate just a bit with washers and you can even try to convince yourself that the vibes are gone.... but believe me, once you install an Advance Adapter slip yoke eliminator or AA SYE for short and a CV drive shaft, you'll know that you had just been kidding yourself. Once installed, your Jeep will drive like butter. It will also be quieter which is something I hadn't expected and you will be doing your U-joints a huge favor.

AW-4 Transmission Swap
Well, it finally got to be time to swap out the manual AX-15 transmission and install an automatic transmission. Unlike some tranny swaps done by others, I did mine because I could, not because I had to. My AX-15 is running strong with no signs of trouble. I opted for the AW-4 automatic that is commonly found in the Jeep Cherokee. This tranny has seen hard use by the local XJ owners and I haven't heard them complaining about it. Although Scott Kruize sold his AW-4 equipped TJ, I know the current owner and it is still running strong. I wanted a tranny with an overdrive so the three speed auto that was available in '98 TJs wasn't really in the running. Besides all that, finding an AW-4 tranny would be much easier due to the plethora of automatic equipped XJs. Many a soccer Mom's XJ has met with early retirement directly after a traffic accident.

AW4 Transmission Override Switch
To turn your AW4 Auto tranny into a "manual" shifting unit is easy. All you need to do is wire a switch that will allow you to interrupt the power to the TCU (Transmission Control Unit). By doing so, you will disable the transmissions ability to shift gears, effectively creating a 3 speed manual shift unit with no second gear. To return to normal automatic operation, simply flip the switch back.

AX-15 to 700R4 transmission swap
Since I started planning this swap last year, I've been checking out other Jeeps and talking with their drivers about their setups. The most common swap seems to be putting in a heavy duty truck transmission with a really low first gear. The transmissions include the SM420, SM465, and the NV4500. Any of these transmissions would have been a good choice but I wanted something different.
Now that I knew I wanted to put in an automatic, I had to decide which one. The easy route would have been to choose one of the automatics Jeep has used with their 6 cylinder motors in Wranglers or CJs. The problem was that none of them is a 4-speed or has a low first gear. I considered swapping a Cherokee AW4, but it is computer controlled, which would add to the complexity of the swap. The TH-700R4, is a 4 speed with a 3.06 first gear. By using this transmission, I would have the overdrive for highway use, a decent first gear, and a future swap to a small block motor would be easier.
Bleeding the Clutch
THE CLUTCH
If any components of the clutch hydraulic system have been disconnected, or if any air is present in the system - 'indicated by a 'soft' pedal - the system should be bled as follows:
Fill or top up the master cylinder reservoir as necessary.
Clean the area around the bleed valve on the slave cylinder and remove the rubber dustcap from the valve, where fitted.
