comancheman Posted January 6, 2008 Author Share Posted January 6, 2008 well the first one was due to stupidity i had a leak between the tcase and tranny rather then fixing it i just added a little fluid every now and then till one day i ran it real low and then over filled it. the frnt pump seal went and i decided to put in a spare aw-4 and np231 i had rather then replacing the seals because i always had tcase shifting problems. the replacement tranny had 180k and 20 years of neglect on it but it still shifted fine wen i bought the truck it came out of. i did a tranny service and put in some lucas tranny fluid stabilizer it drove good for awhile but ive been towing alot with it recently and it had been showing signs till 2day when it just didnt wanna move anymore.

comancheman Posted January 6, 2008 Author Share Posted January 6, 2008 the more i think about it a donor vehicle seems like the best option Link to comment Share on other sites More sharing options...
Pete M Posted January 6, 2008 Share Posted January 6, 2008 The YJ t-case will be clocked up slightly higher than MJ/XJs and you'll still need all the clutch stuff, pedals, and trans mount from an MJ/XJ. Link to comment Share on other sites More sharing options...
comancheman Posted January 6, 2008 Author Share Posted January 6, 2008 i found a 94 xj 5spd close by that was rolled over with 90k. i may jump on this but antidisestablishmentarianism electrical issues will i have when i swap to a standard. antidisestablishmentarianism happens to the computer and the harnesses that are in mine now. and what electrical will a standard require?

Eagle Posted January 7, 2008 Share Posted January 7, 2008 i found a 94 xj 5spd close by that was rolled over with 90k. i may jump on this but antidisestablishmentarianism electrical issues will i have when i swap to a standard. antidisestablishmentarianism happens to the computer and the harnesses that are in mine now. and what electrical will a standard require? You won't have any issues. The ECU will continue to run the engine, and you'll abandon the TCU and harness. Â The 94 XJ will not have a disconnect front axle, so your 4WD indicator light on the dash probbaly won't work. I don't know how to make it work, but there's probably a way.

comancheman Posted January 7, 2008 Author Share Posted January 7, 2008 WOW jeepdew i totally missed ur first post sorry about that. god i must look like an idiot :oops: :oops: :oops: Link to comment Share on other sites More sharing options...
JeepDew Posted January 7, 2008 Share Posted January 7, 2008 if you want to upgrade, the NV3550 is stronger than the ax-15. the nv does have a natural noise when sitting in nuetral. after many people complaining they removed the nv to the 6 speed mopar. Jeep says it was a bad move. If you are interested in this tranny, just let me know, I have skip posts on my on messages, so I know how you feel. no biggie Mike Link to comment Share on other sites More sharing options...

robfg67 Posted January 7, 2008 Share Posted January 7, 2008 comancheman, sorry to hear about your problem. Fluid has been leaking from my transmission/transfer case area for the past 3 weeks.

FxRacing282 Posted January 7, 2008 Share Posted January 7, 2008 to convert to the AX or the NV wouldnt you need a new bell housing? or do they both have internal slave cylinders? Link to comment Share on other sites More sharing options...
Pete M Posted January 8, 2008 Share Posted January 8, 2008 All of the 4.0L transmissions have different bellhousings. The innards I'm not entirely sure about. Link to comment Share on other sites More sharing options...
