87MJTIM

Find the factory service manual online. They're out there. You can search jeep4x4center.com. Scroll down the left side column. Select "Jeep Knowledge Base." Then select "Online Repair Manual." It doesn't list MJs, but you can select the Cherokee model. Select a year. then scroll down the "Category" list for transmissions. There are two sections. You can download these for future reference.

:hmm: I'm confused. There must be something missing. In the first post, you stated that you were swapping a BA10 for an AX15. You changed flywheels. I just did this same swap on my 87 and kept the original flywheel and CPS. These two are engine specific, not trans specific. The swap took a few weeks to complete. Not unusual. When you bolted everything back together, the engine would not start. It was running before you started. In post #9, you state that you opened the dizzy and found "a layer of orange liquid." Is it oil? Do you have a coolant leak somewhere? While you had it apart for the swap, did you "work" on anything in the engine? I am guilty of doing "investigative" repairs: "What is this?...Oops...Oh, shoot!...Where did that piece go?....How does this fit back on there?" I cannot see how a trans swap would have caused the dizzy to break. There must be more happening that we don't know. You say the PO hacked up the wiring. I am at a disadvantage. I am the only owner. My wiring has not been hacked up. Do you still have the old flywheel? Can you reinstall it? I know it will require dropping the trans and reinstalling. :doh: Something else is wrong than just the trans swap.

I light of the current political season, the OP spoke as well as the candidates, but with fewer words. :laughin:

Nice!

I saw this episode this weekend. http://www.truckutv.com/?p=7605 Is this a member's truck? These two do a 4wd conversion on this 88 MJ. How hard can it be? The got the whole thing done in half an hour with lots of time to do shameless product promotions. As a matter of fact, I think they spent as much time promoting sponsor's product as showing the work on the MJ.

It's a definite maybe!

Is your 86 4 or 6 cyl? What is the YJ - 4 or 6? Trans MAY NOT fit across dif engines.

The CPS should go with engine not the trans

Replace both hoses.

I would at least start with the Volvo bottle cap. If the tank is cracked, you should replace it. Throw away the cap that comes with the bottle and use the Volvo cap. (See Cruiser's rant about getting rid of the plastic pressure bottle.) You said the coolant was coming out of the upper hose. Where? At the bottle connection? Somewhere along the hose?

Do you have pictures of making it or a write up? Part numbers? Where to purchase?

Red dye #2. Causes cancer. It was why they stopped making red M&Ms in the 70's. Oh no, wait. Yours doesn't have cancer. I guess they were wrong. "Never mind," said Emily Latella (Gilda Radner, SNL)

OOWW! You lucky B@SS-T@RD. :thumbsup: These were my floors:

What year is the MJ? I ask because Renix (87 - 90) and HO (91 - 92) have different engine systems. This will help other diaguess (diagnose and guess) the problems.

4 or 6 cyl? manual or auto? You will want the matching trans/tcase. The front driveshaft from the XJ will fit. The rear drive shaft on the MJ will need to be shortened to allow for the tcase. The XJ drive shaft is to short. As for the year XJ to get, get one that does not have the CAD. I'm not sure which year Jeep discontinued the CAD. 95? 96?

You'll need to make sure the internal bore of the master matches the internal bore of the slave. If the master bore is bigger than the slave bore, you will blow out the slave. The the master bore is smaller than the slave, you will not get enough movement to fully disengage the clutch. You can purchase a pre-bled master/slave kit from Rockauto (or most auto parts stores). Be sure to ask for the kit for a 93+ XJ. Edit: Do not get the 98+ kits

For Jeep parts, Rockauto, Morris Jeep4x4center, and Quadratec are good sources for parts. At Rockauto, you can specify MJ parts. For jeep4x4center and Quadratec you have to search for XJ parts. The MJ and XJ are almost identical from the front seats forward. A lot of parts are no longer available, so your best option is junk yards or craigslist for parts vehicle.

Check Rockauto. I looked up a 93 XJ, 2.5 clutch/master/slave assembly. Sachs SPH009 $120, plus shipping.

What trans do you have - AX15, BA10, AX4/5? Do you have the internal or external slave (later AX15 and AX4/5)? AFAIK the pre bled systems are only for the external slave systems.

You need to get a full cluster from an 87-90 MJ or XJ. These have the cable speedos. Later HOs have electronic speedos. IDK if the tachs are specific to 4 cyl and 6 cyl. Wiser men then I know for sure. PS: Give us more info on you MJ - engine, trans, 2 or 4 wd, any modifications (axle swap, lifts, etc.)

I already have the D44 in MJ. The 8.25 is on an XJ that was "free". I don't have the 8.8, nor am I looking to get one. Thx thou

A 4.0 will most definitely fit in to an 89. As was stated else where, only the 86 will not "easily" fit the 4.0.
