BA10 = 21 splines AX15 = 23 splines whether internal or external slave.

You will want a 4wd AX15, preferrably from a 94+ XJ. This will have the external slave cylinder.

...or just turn off the lights before shutting off the engine.

There is a delay feature for the lights. This allows you to get in the house at night and see your way in.

275k on mine and still going. I was told by a manual trans mechanic to use Pennzoil Synchromesh.

If they're both 4.0s then yes, they are compatable.

Thanks Fiat. I was not sure what was holding it in place. I now know its just a bolt and O ring. On my next oil change I will rotate it.

I think it the code is 8 12 MX 12 That would make the engine made on 12/12/88. The first # is yr. 2nd/3rd is month 4/5 is engine type 6/7 is day. http://www.jeepforum.com/forum/f12/engine-block-code-help-1027819/ That make the Jeep a later production unit. Prob came with the AX15. (The parts manual give a trans change from BA to AX as mid October.)

Some questions you should find out: What trans did the truck originally come with - BA10 or AX15? Did the PO swap the full trans or just the BH? Is the engine original? I would assume he only changed the trans/BH with the CPS and kept the Renix flywheel.

In this thread and your slave cylinder thread, it confirms that the PO changed the bell housing from a 94+ AX15. He must have kept the CPS from the bellhousing. You will need to swap the CPS off the BH with the socond. (If he swapped engines too, all bets are off.)

Rockauto has one for $120. When you search for the assembly, be sure to specify it is for a 94+ Jeep, 6 cyl, AX15. If you specify for a pre-94, they will try to sell you the internal slaves.

Sloride, that may solve the issue of crawling under the truck. However, in its current location, it drips oil on the starter when I remove the OF. Another reason to change its position.

It looks like the PO did a conversion for the bell housing to the external. 89 was a change over yr from the BA10 to AX15. The truck may have come with an AX15. But the AX15 would have come with the internal slave. However, the slave looks like it came off of an "all-in-one" master/slave system. The master cylinder looks like OE. My guess (and it is just that) is the PO slapped the slave on there to cover up an incomplete hydraulic system.

You did not say if you have a 6 or 4 cylinder. If a 6, then the trans came with an internal slave. (I don't know if the 4s were int or ext.) I'm not sure I understand the hoses you describe, though. Pictures would help.

When the engine was rebuilt the mechanic put the oil filter adapter pointed to rear of the engine. It used to point up. Now, when I change the oil, I have to crawl under the truck and reach up to get the OF off. I cannot pull it out the top with the sender unit and wires in the way. I have tried everything. I see a bolt on the face of the OF adapter. Can I loosen the bolt and rotate the OF adapter back to its original position? Will turn easily? Is it threaded? Is there a gasket or sealer on it?

Are you a person that drives a manual trans, then get behind the wheel of an auto and try to use both feet on the pedals the way some people do? (You've seen the type. They accelerate with their brake lights on or their brake lights keep flickering on and off.) I tried to drive an auto like that once...only once. My passenger and the car behind me didn't like me. (The brake pedal doesn't go all the way to the floor like a clutch pedal. :doh: :oops: )

I was close with the name for the lights Euramtec

I too have the towing mirrors. I bought replacement mirrors from the auto parts store years ago. I do not believe that XJs ever had the towing mirrors. (July 2014 MJOM)

Unless you have chrome mirrors, you can go to just about any JY and get the mirrors from a 1996 or earlier XJ. I don't know if the 97 - 01 mirrors will fit. The courtesy light is a common problem. Especially since your truck is 29 yrs old. Search on CC for a thread about the lights. Try ebay. I got a set several years ago from ebay. I think the name was Eurotech, or something like that. You could get doors from a 96 and earlier 4 dr XJ. The 2 dr will not fit. The 97+ doors will fit, but will require some modifications. Also, the contor shape is different. The front diff is probably a Dana 30. The rear could be an AMC 20 (desirable) or a Dana 35 (not so desirable.) Welcome to the addiction.

What is a "manual transmisson cable"? Is the guy trying to sell you Shine-ola?

I recall that several years ago CA was proposing increased mileage and emission standards for new vehicles. The auto industry responded to CA with the statement that the only way they (auto industry) could meet the proposed standards was to produce and sell more vehicles with manual transmissions. I don't see a problem with that!

Manuals for me. :thumbsup: I've three autos and have not liked driving any of them. We got them for towing a travel trailer.

That's what I got with the GS leafs. I put 2" spacers up front to level out the truck. If you did not want any lift from before, like Eagle said, you should contact GS and comment/complain.

This may sound like a dumb question, but, are sure all of the bolts are off? :dunce:

I've put in my 87 BA10 and an AX15 in my CJ7. Works good.
