87MJTIM

From a '87 Electrical FSM (I tried to rotate it, but photobucket would let me.)

OK non Jeep: 2005 Honda CRV 220,000

To do this swap, I guess you are going from a BA10 to the AX15, you will need the cross member and the t-case shift linkage. The cross member is diff from the BA to AX. Also, (I have been told on this forum) the shift linkage is also diff. I don't know if it is because of the BA/AX change, or a change in the t-case in later years. Rockauto sells the bushings. You should get one for a 74 CJ5 with a 304 V8. There are several write ups on CC about the BA10 to AX15 conversion.

Ok, slightly off topic...but not too far. My 84 CJ7 has a Dana 300 t-case. The FSM says to use the same oil as the trans. The D300 is gear driven, not chain. So, is it OK to use 10-30 in the D300 t-case?

It was both the harnness and headlights.

FINALLY GOT THE UPGRADE DONE! This was a relatively easy process. Original lights, low beam After upgrade, low beam Before, high beam After, high beam I have not taken it out on the road yet.

General Spring KC, MO http://www.generalspringkc.com/Leaf_Springs_Jeep_Comanche_s/1954.htm They offered CC discount.

What about Pennzoil Synchromesh? I had my BA10 serviced last year and shop owner told me to use that and not regular 75-90. I am putting an AX15 into an '84 CJ7 and was going to use Synchromesh in that. The trans came out of a 90 XJ.

Parts diagram shows the 2.5 is perpendicular to the starter, 4.0 is parralel (spelling?)

S/B 2 bolts and 1 wire You may have to remove the bolts from opposite sides.

Check the top of the fuse block, just under the MC, inside the cab. Make sure it isnt leaking there. Then replace the MC to be safe.

I did not ask. I left my offer for $500 open, but I won't wait by the phone for a call.

I wanted the parts. I am not looking for a driver.

Went to look at it again. Met the person selling it - not the owner. It started and ran good. But.... Coolant was dripping out of the cap and some connections were loose and coolant was dripping from those. Guy said the radiator was just replaced (???) Valve cover drenched with oil. Blow back? Engine bay and block have not been cleaned since it left Toledo, OH. Body panel under the battery was completely gone. I could see the grass under the truck. The heater core was removed. Guy said the PO had removed it. (So the current owner is not the original owner.) He said the AC worked. Yippy! There is no head liner. Completely gone. Again, PO removed. Said the speedo doesnt work. All other gauges worked. So he said. Told him $500. He said too low. I said if it were 4wd it might be worth more, but it was too far gone for anything but parts. Which is what I would use it for.

My wife saw this on the side of the road Saturday. I went out to look at it Sunday. '92 Elimimator, 4.0, auto, 2wd, short bed, gray interior. No spare tire or carrier, passenger front link is snapped (see picture), bed is rusted on both wheel wells, tail gate is rusted. Rear bumper has rust on the bottom, but not too bad. Interior is clean with original radio. Drivers seat has a seam tear. Looks like factory bed liner. Selling as is - with tool box. Asking $1800 OBO. I have not heard it run or drive.

I put on General Springs with the 3:2 military wrap. My back end was lifted approx. 3". I had to put 2" spacers up front to level it off. I am running 235/75/15. July '14 MJOM. The spings are $220 each. They sell a 3:1 leaf for $140. http://www.generalspringkc.com/Leaf_Springs_Jeep_Comanche_s/1954.htm This is before shipping. If you order these, ask for a CC discount.

I was referring to the manual gear boxes. I was not aware that the autoes did not change. Learn something new everyday. Now i can go back to bed.

The tcase switched from 21 to 23 in mid-89 when the BA 10 was discontinued for the AX15. If you are changing to an AX15, then get one from a 94+ XJ. These came with the external slave. The BA10 and 1st generation AX15 (89-93) used internal slave cylinders. It is not a question of "if" the slave cylinder will break, but "when" it break.

273000 original. Rebuilt 5000 miles ago. No real issues, just old and tired. July 2014 MJOM.

I had this same problem a few years ago. It turned out to be the turn signal switch. I had running lights, turns and flasher, but no brake lights. (Reverse has not worked in years.)

My thoughts, too. Maybe something is restricting the exhaust. The back pressure chokes the engine and kills it. Once the pressure drops, you can restart it. Just my 2¢

Bassed on those years, the trans will bolt right up to the 4.0. As for the Tcase, if the D30 has the two piece CAD, you can perform the CAD fix (search in the DIY section) and the vacuum line are not necessary. If the D30 is from a later year (don't remember when) the CAD was eliminated, so the same rules apply.

So, back to your original question: As long as the 242 has the plug, you will need to check to see if your existing wiring has the appropriate harness and your cluster has the lights. You may need to swap gauge clusters. I believe most harnesses were universal, meaning AMC made one type to handle all possible options.

For my education: Is the 242 "Full Time Select Trac" or "Part Time Command Trac"? The FSM has the PT Command operated by vacuum. The FT Select is operated by a mechanical switch.

If I am not mistaken, the front axle 4wd light is vacuum actuated. The light is triggered by a vacuum operated switch on the t-case. According to the 88 electric FSM, the 4.0 auto is wired differently from the 4.0 manual and 2.5 (auto or manual).
