42rle

Hi all! new to the forum and have a strange thing goin on with my 05 rubi auto trans. In early January I felt the Jeep slip going about 65 on the highway. The RPMs shot up but no power to the wheels. I let off the gas and I immediately felt re-engagement and I took off just fine and got home...

On my way back home to “social distance” with some loved ones my automatic transmission in my 06 tj crapped out on the freeway. Wondering if anyone has any recommendations where I could pick up a good remanufactured unit near Sacramento? I’m about to have a lot of free time and and access to a...

Hey everyone. I've got an 06' X with the 42rle automatic that experiences the occasional hard-shift and some slipping. Inching up to 140k miles on the jeep and I would realllllyyyy like to swap to a manual trans (preference). That being said, I have an opportunity to get EVERYTHING I need...

I have the infamous issue with the 05 and 06 42rle bad shifting because of the bad PCM. Now, because that is discontinued I am looking for an alternate option. Whether that means swapping it for a different engine and tranny combo, swapping it to a manual, or another automatic and get a new...

This is a little install guide on a switch I put in several years ago. It works well so I thought I’d share the process and some thoughts on it. I have a hand throttle below the switch visible in the pictures, it doesn’t get in the way Why switch at all? The 42RLE drives much better with the...

Well hi guys (&or gals) I just joined the forum, probably for the same reason as many of you. I have all of issue with my trans and have no clue what to do next except rebuild. The jeep is a 2005 Wrangler 4.0 42 RLE ,235 75 R15, factory height. About a month ago after leaving the house (also...

Hello everyone, I just recently got a 2004 TJ, my first Jeep. I love it so far. It has 130,000 miles on it, 4.0L, 2.5" lift with 31s, stock gearing at 3.73. Everything so far is functioning just fine. The steering is pretty loose (I don't know if that is a Jeep thing). There are three or four...

Working on my first transmission flush and filter change. One of the pan bolts is worn and the socket slips so I wanted to replace it before it gets worse. After scouring the internet the only part number I could find for this was here...

I'm hearing vibes at around 45-55 mph (actually higher, I found out today that I'm indicating about 12% off, but ignore that, I'll get that fixed), but the vibes only happen in 4th gear. (4 speed auto). I've been getting around this by switching the O/D off until I'm at 60, but obviously...

Hey all. I am about to start building my LJ into something usable for on and off road. Much like most everyone, this is also my daily driver. Considerations for things like driving many miles each day/month are real for me but not be all end all limiting factors. I want the Jeep to run solid...

My PCM is showing P0106. That means that the next issue is with my 42LE transmission shifting. No new are available from MOPAR until estimated 12/31/2018. When ever I am told end of the year I get nervous. Also that costs 999.99. Ouch. Looked for a rebuilt. Nope none available. Finally...

So i have a 2006 X with an auto. On the way to work this morning the check engine light came took it to my local parts store to have the codes checked. This is what it showed. Gas cap loose.( not worried about this one.) P0218 high temperature operation activated P0714 transmission temperature...

Could use some help please 2006 LJ 137k miles. 42RLE Repaired normal stuff ( fuel pump, catalytics, a/c compressor and all lines). But, this week trans gets “stuck” in second and will overheat and go into limp home. Now, if I force it in first by shifting or I have stopped completely and then...

I have a 2006 Unlimited with a automatic trans that has started to shift hard from 1st gear into 2nd. It happens when the jeep is typically cold and it only happens once. I checked the transmission fluid and it was very low at normal operating temps and didn't register on the dipstick. I slowly...

Hello! I have an 06' TJ with the 42rle in it. I've got 125,000 miles on the jeep and it runs like a top. The only issue is that I'm almost positive my transmission has finally bit the dust. Fluid and filter were done at 120,000 and my computer is good. Just topped the fluid off because it was a...

My coworker and I have been discussing the risk of replace (not flush) the 42rle fluid on his LJ that has more than 100, 000 miles on it and chances are that the same never has serviced. I know the subject is quite conflictive due the different experiences, myths, mentality and/or knowledge, but...

Today while driving home a random check engine light can on. Nothing odd to be noted while driving at all. Scanned with my obd reader and it says P0700 & P0740 The P0740 is the main code. It reads tcc out of range. Any ideas/help would be great. The transmission shifts fine and has no issues...

Ok so I posted images the other day of what I think are trans cooling lines leaking. Possibly unrelated: last time I had issues with missing 2nd gear I was low on fluid. My son decided to add fluid for me (it may be over full as I checked it and it was over the cold full mark) I’m thinking I...

This flush was done on a 32RH transmission, but the procedure should be mostly the same for a 30RH and 42RLE transmission as well. I wanted to replace the filter and get all the fluid out of the torque converter. So I thought I would give it a try. There were some questions I had, but I was...

I've got a 2004 TJ with a 4.0 & 42RLE. About a month ago I replaced the original 42rle at 125k with a reman unit from Powertrain Solutions. I also added a Derale TJ transmission cooler to keep things cool and bypassed the radiator cooler as per the reman companies request. Most of the time the...
