42rle

I've looked everywhere to find a solution hopefully someone here can help. The check engine light came on, got P0850, checked to see if it would start in any gear and it does, i replaced the switch, checked if it would start in reverse and it did not, checked in drive and it did not start, put...

I picked up this 42rle about a year and a half ago for a project that never panned out. It came out of a 2005 LJ with 52k that was getting an LS and 1-tons. I paid $800 for it & it’s been sitting in my garage ever since. Looking to get $500 for it and pass along a deal here rather than deal with...

TL;DR, I hate my 42RLE, I don't have the money for Novak bits (especially since I live 1 ocean and 2ish continents away) so I made my own Manual conversion using some CAD, a hole saw and a local sheet metal supplier. She's got about 1,400km on her since her surgery, going strong with a hint of...

INTRODUCTION I own a 2006 Jeep Wrangler Unlimited (LJ) Hardtop with the 4.0L and 42RLE transmission. I bought it back in 2018 with just 26,500 miles on the odometer. It came from Florida, where it likely spent its first 12 years in someone’s garage as a weekend beach cruiser. Everything was bone...

Hi all, I’m having an issue when changing from drive to reverse and back. You can hear it changing which I never could before. It also physically moves/ wobbles the car when changing. Also after starting off from cold it will not change up on the first gear change when it should. It over revs...

Hey TJers, I bought this as a back up for my RHD TJ before I started diesel swapping it and just found it buried in the back of my storage unit. I bought this in the spring on 2018 as a back up because I was debating doing the RubiCrawler setup from Advance Adapters with this transmission...

2004 Wrangler 4.0 42RLE automatic Hi all, I've made a post about a year ago now of a noise with my Jeep. I was never able to figure it out and life has gotten in the way so it has stayed in storage on jackstands. Today I took it out for a drive to jog my memory of the issues it was having...

Hello Over the past 6 months, I've been dealing with some off & on issues with my LJ. Seems to be all centered around the transmission or the PCM. What all started this was some weird automatic shifting & a squeal when I would come to a stop—seemed to be a relatively "common" issue(from what I...

Will a 42rle from a 2005 LJ swap seamlessly into a 2004 LJ? I know there are differences with the integrated TCM/PCM vs separate TCM & PCM in those years. Are the transmissions themselves physically the same though? Are the plugs/connections all the same?

I'm currently having a problem with my transmission shuddering when entering overdrive, and it sometimes goes into limp mode when overdrive is off. It shifts great between 1st and 2nd gear but always shudders as it's going into overdrive. Could this be multiple problems or just one?

okay, I'm getting out of ideas.... there has been a few times my 06 rubicon with the 42rle get stuck in 2nd gear, I turned my jeep off and on and it was good to go... a few weeks my jeep got stuck in second gear again but now I haven't been able to get it out of the limp mode.... the oil was...

Hello everyone! I'm trying to figure out what this sound could mean (in video) when my transmission shifts. I do not get any weird vibrations at all when it make the sound, nor am I getting hard shifting (was experiencing some rough shifting which went away after replacing faulty O2 1/2 Sensor...

Hey all just looking for some suggestions or clues on a noise my jeep is making. Last year I was having transmission issues throwing codes, getting put into limp mode, etc. Local transmission shop quoted me $2800 for a rebuild so i ended up swapping in a used lower mile transmission from a same...

So I bought my jeep in the summer and have never been able to get it to not kick into limp mode. Like an idiot I decided I was going to take the valve body out. Cleaned her up, buttoned it back up, but now my shifter seems to be fouled up. I tried taking it all back apart and buttoned it up...

So as the title implies, is it possible to remove/modify that adapter plate or even the 43rle output shaft to mount NP231 closer to the front of the car? Got this idea when i was rebuilding the NP231 while doing the SYE, that adapter seems kind of huge and mostly filled with empty space.....i...

Howdy folks, I decided to service my trans yesterday. Not because I was having issues, but because I haven't done it in the years I've owned the jeep and I felt like it was a good idea. The fluid smelled good and had a nice red color to it. Not burnt or stinky like I've smelled in bad...

I have 2005 with the 42RLE, 120K miles. Was driving home and the converter started locking and unlocking. Came to a stop and took off again and it started off in second, went thru all the other gears but no converter lockup. Pulled a 1776, 700, and 841 codes. Changed solenoid block twice. Fluid...

Let's start this off by making it clear: this is not a real "How To" as I have now only been involved in this project once. There's a lot of "figure it out" in this. However I do want to document an NSG370 to 42RLE swap in case it will help someone else later (it also works in the reverse ;)). I...

This code has thrown on me twice, and both time were under similar conditions. I've read a lot about this code, and owners seem to either "throw parts and money at it, plus a prayer or two" - and they may get lucky, or they may not - or they're of the "get rid of it and go with a manual" camp...

Wanted to start a discussion about transmission coolers, specifically the Setrab that @mrblaine uses. I know the a lot of guys will just copy him and run what he runs, because of his experience and knowledge. However, He builds jeeps to run in the desert and climb mountains. I'm planning out...
