Either turn off "auto correct" or use a spell checker. It is hard to follow what you're saying.

The was good.

Self employed CPA. I prepare tax returns for small businesses and individuals. As long as the govt keeps writing and re-writing the tax laws, I have job security. As Ben Franklin once said: There are only two certainties in life, death and taxes. (I'm not a mortician.)

TV weather just reported Frederick MD 32.5"...and still coming down.

Don't think I am taking it out today. Got about 22" and still coming down. We don't usually get this much snow here in the mid-Atlantic.

Bench or bucket seats?

I thought that also. But, he said a compression test came in at 140 - 150. I would look at the reservoir bottle and cap. On mine, the cap has blown and would not hold pressure. It could screw down "tight" but leak at pressure. Purchase the Volvo cap from NAPA. Another clue is that the bottle fills up when hot. The anti-freeze is expanding from the engine to escape through any crack. It may be due to a crack in either one. Good luck. Let us know what you find.

Yes, the XJ engines will swap over. However, you will be going to HO from Renix. You will need to rewire you MJ for the swap. Also, the cylinder head may be 0331. These are prone to cracking between cyl #3 and #4 (or 2 & 3). There are lots of write ups on this.

3:1 - the first is the number of main leaves, the second is the "helper" spring. The second gives additional support for heavy loads. 3:2 - has an additional helper spring. I will find photo of my springs. 3:2 Springs Military wrap

Matching gears is good thing!

You will need to have the rear drive shaft from the XJ lengthened, or the DS from you MJ shortened. Most everything else should be a direct swap. There are lots of write ups on converting 2wd to 4wd. Just search on here for it.

Two suppliers of springs for our MJs are General Springs out of KC, MO and Hell Creek. I have GS on mine with the 3:2, military wrap. These lifted the rear by about 3" from the old sagging springs. I has to put 2" spacers up front. I kept mine SUA.

Did you install a "switch" or a "sending unit." There is a difference. A switch just turns on/off the idiot light. The sending unit sends a signal to the gauge which translate it to read the pressure. In your first post, you said "Changed pressure switch." Was it a switch or sending unit?

You can swap the individual gauges from one cluster to another.

I suggest test the CPS. See Cruiser's Tips for Renix engines.

What year was the YJ you got the tcase from? The output shafts changed at some point in Jeep history. As for the front drive shaft, the lengths are different between a manual and auto trans. An AW4 is longer than an AX15. That means a DS from an auto will be too long for your manual. Sorry.

Welcome to the madness. Oh, I guess you have been there from the beginning. Do you remember mine coming off the line? :laughin:

Sounds like a PO has made all the necessary changes already. Since it was born a 2wd and is now a 4wd, the things I would suggest you check are: What trans is now in it? An 88 4.0 5 spd. would have come with a BA10/5. Is it still a manual? Is it an AX15? What is the tcase? The most common is an NP231. Although, a NP242 can be found. Is it part-time 4wd(231) or full-time 4wd(242). Look at the tcase shifter. What front axle was installed? Most likely a Dana 30. What are the gears: 3.07, 3.55, 3.73 or 4.10? There maybe a tag on the diff cover that will say. What is the rear axle? It probably came from the factory with a D35 and 3.07 gears. Although, it could have a D44 (more desirable) but still 3.07 gears. Picture looks nice. Welcome to the madness!

Lots of write up on Jeepforum.com

The 87 to 89 1/2 had the BA10. From 2nd half 89 to 93 the MJ/XJ/YJ came with the AX15 with the internal slave set up. From 94 on, the AX15 came with the external slave. I would recommend the 94+ XJ if you just want the trans. Other parts are HO 4.0s. You can use some of the parts, but not all. Also, the tcase that came with the BA10 has 21 splines. The AX15 uses 23 splines. You will need the matching tcase with the AX15. Or, you could rebuild the 21 spline tcase to change the input shaft. For a Youtube video, check out Bleepinjeep for this change

So far, Sherman seems to be the only panels close enough.

Any year XJ that came with an AX15 will make a good donor FOR THE AX15. A YJ with an AX15 has a different clocking for the tcase.

Sorry for the confusion. I hope you were not offended. It is just that the shift tower on the BA doesn't come apart like the AX.

Thanks for the responses. However, I have read that XJ panels do not fit: wrong profile and too long for the MJ. Also, I do not do rock crawling. My MJ is 99.999% street. I am not looking to get rock guards. Thanks anyway.

I am leaning towards the Sherman panels. Are there other suppliers besides these two?
