RynoMJ Posted February 18, 2007 Share Posted February 18, 2007 In 1988 what are the spces on an automatic comanche, I know it came with the NP231 but was the Aw-4 tranny in use, and is the aw-4 good for offroad? Link to comment Share on other sites More sharing options...
DirtyComanche Posted February 18, 2007 Share Posted February 18, 2007 If it has a 4.0, it'll have an AW4. They're good. You can get a manual shifter for them if you want to be able to lock out 1st gear. And they do benefit from an aftermarket tranny cooler, but it's not like it's absolutely necessary.

RynoMJ Posted February 19, 2007 Author Share Posted February 19, 2007 OK yea it has the 4.0 L forgot to mention that, and how does the automatic do offroad? Link to comment Share on other sites More sharing options...
87manche Posted February 19, 2007 Share Posted February 19, 2007 OK yea it has the 4.0 L forgot to mention that, and how does the automatic do offroad? I wish I had an auto, does that say it all? seriously, the AW4 is nearly bulletproof with the stock drivetrain, you'll kill the d35 first. If you really plan on abusing it then get a HD trans cooler.

RynoMJ Posted February 19, 2007 Author Share Posted February 19, 2007 I don't plan on abusing it, but is it able to handle a 44 if i plan to upgrade at a later point? Link to comment Share on other sites More sharing options...
87manche Posted February 19, 2007 Share Posted February 19, 2007 there are people running 60's f/r that still have an AW4, it really is that good. they used it in supras, behind turbocharged 6's, it'll take anything a 4.0 can dish out, as long as you don't overheat it.

DirtyComanche Posted February 19, 2007 Share Posted February 19, 2007 Even then they seem to hold up... There's guys on naxja that ran them out of oil and it didn't kill them :nuts: Link to comment Share on other sites More sharing options...

Pete M Posted February 22, 2007 Share Posted February 22, 2007 I read somewhere that, if you do find a way to kill it (anything can be broken with enough neglect of abuse), it's better to just swap in a junkyard AW-4 than to try rebuilding the old one. Not sure why though. :hmm: Link to comment Share on other sites More sharing options...

Not sure why though. :hmm: they don't die frequently, so probly very little support in rebuild parts. which may mean stealership... then you have like 35377456536 in your local yard, becuase if the jeep died. it probably wasn't the AW4 that caused it. :brows: my brother busted a tranny line in the mud, and overheated his tranny, and all that good stuff and it shifted like absolute PISS for a week, he flushed it, put in a b&m cooler, and it shifts smoother than glass. literally, you cannot feel most of the shifts. (edit: this is all while pushing 35's on a D44 axle.) Link to comment Share on other sites More sharing options...

I have a 95 2dr xj that i bought, but it doesn't shift...the kid abused it but there's no way it's the tranny. So I'm basically down to an electrical issue, a bad Torque converter, TCC solenoid, Shift Solenoid, or TCC relay. I HAVE NO CLUE! PLEASE HELP ME!!!!!!! (p.s. i've never worked on an auto tranny before...so i'm learning) Link to comment Share on other sites More sharing options...
Pete M Posted February 23, 2007 Share Posted February 23, 2007 Check the fuse and it could also be a bad trans computer. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted February 23, 2007 Share Posted February 23, 2007 Check the fuse and it could also be a bad trans computer. I'm inclined to think the computer is fine...after all it has 160k and didn't fail yet. i will check the fuse...when i find which one it is. the reason i'm very inclined to think it's the torque converter is that he BEAT on it...squealin from every stop sign/light, and brake torquin/doin burnouts as much as possible with the limited slip rear end. what it does is you put it in gear, and it won't drive. but it doesn't make ANY strange noises at all. it just won't go. but when it's cold it seems to go just a little bit. the fluids look great, engine revs and runs great. so i have no clue what it is?

Kenosha Warrior Posted February 23, 2007 Share Posted February 23, 2007 There's a separate computer for the tranny in a XJ. It may be toast, but from what you describe, it may be a bad Tq Con. Link to comment Share on other sites More sharing options...

Now I'm thinking about that...If the torque converter went bad, it would have shown symptoms of it before then right? like slipping and such? and if that's the case, then It's gotta be a shift solenoid or TCC solenoid/relay. or computer/fuse. I'm pretty sure it isn't the torque converter, and i'm DEAD CERTAIN that it cannot be the tranny itself. cause were it the tranny, there would be all sorts of strange noise....?

carnuck Posted February 26, 2007 Share Posted February 26, 2007 I have the AW4 going into my "lifted" '84 J10 (Comanche's big brother with D44 front and D60 rear, 52" tires and NV241 rock lok tcase with 4:1 and a 4.6L stroker in front of it) I know it'll take it fine. I loaded the old truck the trans was in up with 5 tons of stuff and hauled that through the mountains here. Not a whimper with a decent cooler. (I usually only see them die when people put the Mopar +4 fluid in instead of Dexron ) Link to comment Share on other sites More sharing options...
87manche Posted February 26, 2007 Share Posted February 26, 2007 you say you checked the fuse, there are two. One is in the fuse block and it's marked trans, there's another one, INLINE on the power wire that goes to the TCU. I'd poke a multimeter around on the TCU harness and see if it's got 12V going into it. I believe it's a yellow wire, but I can't say for sure since I'ma 5 spd guy.
