Selling my engine and trans, 2004 4.0 and 42rle with advanced adapter rubicrawler with aa twin shifters. 147k miles, rubicrawler installed in late 2019 early 2020 by previous owner. Motor and trans run strong with no leaks or issues, im pulling for the ls swap i just finished putting together.

Hi all, The past few months I've been having troubles with my Jeep. I've looked around all over and made a post here trying to diagnose it and have come up with it maybe being the TCM. Have one ordered up and it arrives tomorrow! But today the problems got worse. I have driven the TJ 3 times...

I have been having a hard time finding the proper parts for my transmission. I believe I have the nv3550. I Know I at least need a gear cluster. do you guys know of any trustworthy place i can buy my parts?

my engine light came on today. the engine doesnt seem like theres anything wrong it sounds all normal. but when shifting into or out of second gear it almost always grinds, this has been happening for a couple months. does anyone know what the engine light is or how to diagnose it? any help is...

My ax-15 transmission is almost in need of replacement. Syncros are out in second and third can’t even hardly get it in gear sometimes. I can’t find anyone in my area that will work on it to replace them. Would you recommend buying a new one or a reman? Also any recommendations on where from...

I've owned my 2001 Jeep TJ for almost a year now. It's a 6 Cylinder with 170k miles and 3-Speed Automatic Transmission. When the Jeep is at a full stop and I put it in Drive or Reverse the shaking/vibration is so bad I can barely see out of the mirrors. When it's in park or neutral there is...

I have tried finding someone who has discussed this issue in the forum before, but wasn't able to find anything. I have a 2006 LJ that will not go into gear... at all. I have checked the shift linkage bushing, still good. The shift actuation rod under the shift handle is good to go. The shifter...

I have an 05 tj with 35" tires trail riding yearterday, climbing over rocks I heard a slam noise now I can shift to each gear let off clutch and it does not move does not stall as if its in neutral with clutch released help I zm f

So I have a 2000 tj with an ax-15. I know doesn’t make sense lol. As nv3500 or 3550 can’t remember which it is that comes stock in my tj is extremely expensive to rebuild for a 1/4 ton truck transmission when it went out last year I swapped an ax-15 out of a yj into my tj. It had an unknown...

Hello all, I recently tore apart my NV3550 and replaced all of the synchros. I checked all of the bearings and determined that they were all good, so I did not replace them. I am confident that the transmission was assembled correctly, and everything felt smooth and solid after going back...

Never Installed / Still in the box 97-02 TJ skid Had plans to mount this, but after putting a dynatrac front axle in, it won't bolt up without modification ( which I don't plan to mess with). Link for details...

starting this thread to document my swap instead of doing it after the fact when my memory is fuzzy. Background: my NSG370 pops out of reverse. In street use it's tolerable but it's exacerbated when backing against any resistance, such as uphill (like the 8% grade on my driveway) or if a tire...

I have a 2001 TJ 4.0, with the clutch OUT it sounds like there's marbles rolling around or rattling, when I push clutch in it goes away. And unless I use a little more "force" than I should have to, it will grind going from 1st to 2nd. My initial thought was throw out bearing, but now I'm second...

2002 TJ 4.0 I first noticed it at red lights. A grinding/rattling sound coming from beneath me that disappears when I go into neutral. And it's not noticeable when I'm driving, probably drowned out. I've been leaking ATF for a while but I thought it was just a bad pan seal and now it has low...

Starting to get a bit frustrated with trouble-shooting so hoping maybe someone has come across a similar/same issue that may have a suggestion or two on anything else to test prior to opening up the wallet :-) Purchased a 2005 TJ SE, 4.0 back in december via facebook marketplace and issues...

This is a look into how I use a PID controller as a temperature gauge and alarm for my transmission. Automotive temperature gauges, even expensive ones are normally pretty poor at low temperatures if they even work at all. PID controllers take a variety of high quality sensors that work over...

Hello all! I’ve since recently purchased an 02 wrangler with the amazing 4.0 and 32RH to replace my 2.5l ax5. The old jeep was fantastic but ive been blessed enough to get a new job that allows me to financially afford this new to me Jeep. I’m an aircraft mechanic and love working on my Jeep...

So I had the Jeep (06, A/T LJ 4.0) back in the shop for a leaking RMS and a small transmission oil leak. This is my second attempt at getting the RMS leak fixed. First attempt was my local auto repair shop, not a jeep/4x4 specific shop. Was told by the shop the leaking transmission oil leak...

Flex-a-lite direct fit transmission cooler. This bolts in using the grille V-bar bolts then just running some hose to the cooler from the radiator. No fabrication or weird zip ties. I have been using it with the radiator bypassed for the last couple years and it stood up to the Arizona heat...

My LJ just started making this noise this morning coming from the transmission. When the clutch is fully released, I can hear it come from the transmission. When the clutch is pressed in, I can hear it come from the engine area. When in between, I don't hear it at all. I've got a 6 speed manual...
