comancheman Posted January 6, 2008 Posted January 6, 2008 so i blew my 2nd aw4 today in my 89 comanche 4.0 and I'm thinkin about goin to an ax-15. I'm just looking for some advice from people who have done this conversion. antidisestablishmentarianism other parts will i need and what years will fit best. i may have a lead on one from a 94 yj h.o. any help is appreciated.
comancheman Posted January 6, 2008 Author 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 Posted January 6, 2008 the more i think about it a donor vehicle seems like the best option
Pete M Posted January 6, 2008 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.
comancheman Posted January 6, 2008 Author 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?
comancheman Posted January 7, 2008 Author Posted January 7, 2008 wats the deal with the ax-4, good tranny or bad. would it be worth my time to swap?
comancheman Posted January 7, 2008 Author Posted January 7, 2008 upon searching this forum i believe that it is only compatible with the 4cyl. guess i should research before i ask. correct me if i am wrong though
JeepDew Posted January 7, 2008 Posted January 7, 2008 I have an NV3550 that I was going to put into my 88(out of an 03 TJ), until my lazy producer wanted to switch to auto. it inlcude tranny bellhousing , slave and master cyclinder I paid $750.00 plus shipping if interested, let me know Mike
Pete M Posted January 7, 2008 Posted January 7, 2008 upon searching this forum i believe that it is only compatible with the 4cyl. guess i should research before i ask. correct me if i am wrong though Yup, it's compatible with the 2.5L and 2.8L only.
comancheman Posted January 7, 2008 Author Posted January 7, 2008 thanks pete your always on ur game! do i have any other options for a straight forward conversion to a standard transmission other than the ax-15 and the peugots?
JeepDew Posted January 7, 2008 Posted January 7, 2008 thanks pete your always on ur game!do i have any other options for a straight forward conversion to a standard transmission other than the ax-15 and the peugots? Did you see my post..... :cheers:
comancheman Posted January 7, 2008 Author Posted January 7, 2008 the nv3550? is that out of a dodge? will i need a different bellhousing?
Eagle Posted January 7, 2008 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. 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 Posted January 7, 2008 am i correct that mid way through 88 the ax-15 became the only standard tranny behind the 4.0 in xj/mj's?
Burls Posted January 7, 2008 Posted January 7, 2008 am i correct that mid way through 88 the ax-15 became the only standard tranny behind the 4.0 in xj/mj's? mid 89 for the change over
comancheman Posted January 7, 2008 Author 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:
JeepDew Posted January 7, 2008 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
comancheman Posted January 7, 2008 Author Posted January 7, 2008 thanks jeepdew but i don't have that kind of money around right now. if i win the lottery though ill let u know :cheers:
robfg67 Posted January 7, 2008 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. I have just been motivated to diagnose/fix ASAP!
FxRacing282 Posted January 7, 2008 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?
Pete M Posted January 8, 2008 Posted January 8, 2008 All of the 4.0L transmissions have different bellhousings. The innards I'm not entirely sure about.
JeepDew Posted January 8, 2008 Posted January 8, 2008 I have the tranny, bellhousing , slave and master cylinders. everything you need to swap in....except the man power.... :brows:
