Forum: Engine, Transmission, Transfer Case

I've got an 05 LJ and need a new/refurb PCM, anyone have recommendations for a reputable company? Thanks

Has anyone on here done a LS swap in there LJ? I'm researching which LS I want to swap into my 2006 LJ. Right now I'm considering LS3, L86 with 8L90 trans.

Hey everybody, Haven't been on here much, hope you all are doing good. Question for you. 2006 LJ manual. Does the belt tensioner assembly bolt into a removable bracket and if so what is that thing called so I can get another one if needed? Issue: Belt was squeaking. Found the tensioner...

Hey guys, just wanted to ask a quick question. I'm replacing the OPDA in my 06 LJ and purchased the Crown Automotive replacement and was wondering if anyone knows if this hole in the picture is supposed to be there? TIA Sent from my ONEPLUS A6013 using Tapatalk

Ok, this issue is strange, so bare with me. 06 LJ automatic. I have this issue mostly when it's cold or really wet. When shifting into any gear, the shifter feels "crunchy"....feels like there's ice or broken glass inside the console. Also, when this happens, sometimes my key won't turn all...

04 LJ 80k miles. No check engine light and no upgrades to engine. 3 times it has just shutoff during a hard left (U-turn). Well today it did it driving straight, luckily it was in a parking lot and a slow speed. Any ideas what could be a possible cause???

I know that Jeeps have like 10,000 catalytics. Why? Dunno! Anyway, I went to the local "Peppy" autoparts store to find this: And apparently, Amazon is the ONLY place to get it. :banghead: So here's my dilemma... Whenever my overdrive kicks in, I get a sulphuric (rotten egg) smell. It's...

Has anyone else on here had to deal with this problem? Guess I'm going to do the Hoppe mod - replace fuel filler hose with GM part that has the check valve built in.

The only way to describe the issue is there are times when it feels the drivetrain is fully engaged and all the power from the engine is getting to the wheels. There’s a strength to the acceleration, and you can feel the torque of the engine when accelerating. At other times the engine is...

Sunday, on my way home from work, I noticed the tranny slipping. Then I heard what sounded like a power steering pump low on fluid, and it really started acting goofy. This is the first issue I have had from the transmission, so I pulled the code. P0700, General Transmission Problem. I was...

Have an '06 rubi unlimited, with a 3.5-4'' lift. Ever since the wife and I have owned it over the past 4 years, Ive noticed this clunking noise everytime I press in and let off on the clutch. If I operate the clutch smoothly at a moderate RPM it shifts smoothly and you cannot feel it in the pedals....

Hi everyone, I own a 2005 jeep unlimited LJ, 6 cyl. auto, 31 inch tires, the problem I'm having is extremely poor gas mileage. I get 150 kms per tank in the city and close to 200 on hwy. I know it should be better, but it's not. I'm in Toronto, Canada, and was wondering what kinda gas mileage you...

I am about to pull the trigger on an 06 Rubicon with an auto trans. After doing some research and seeing the issues with the 42RLE it has me slightly concerned. While I have seen a few bandaids to address the issue, I do not think I have seen a definitive solution. Is there a permanent fix to...

OK so over the weekend I was wheeling and the dang cable jumped off of my automatic shifter lever in the middle of a long rocky descent. Jeep was stuck in 4Lo and 1st gear and the lever just flopped around. I know it is common for the cable to pop off underneath the jeep, but this was at the top,...

I just got a job at a local stereo shop. They are in a nationwide buyers group for parts. I found out that I can obtain items for my vehicles at 10% above our cost. My LJ has 35's, and needs the speedo reprogrammed. I can take it to the dealer and pay to, or I can buy a tuner that will do it. ...

I've posted stuff here and there around the forum, but I'm gonna stick all this here in cse it might help someone in the future. Plus I'll be able to find it later. Back in July I was driving home from work in the ol LJeep and the check engine light came on. Jeep drove fine. Let it sit for a few...

Hey y'all Any one running a trans cooler? If so: What kind, cost, pros/cons etc.

took my baby out for some light wheeling for a few hours last Saturday. Did fine. Was a little dusty out (not horrible) and I did run through a single puddle (axle deep). I didn't push it very hard and it did great on the trails. Loaded it up on Saturday afternoon and brought it home. My boyfriend...

I am looking into doing a Belly up on my LJ. Has anyone done it? What issues if any did you run into? I want to have all the stuff I need to complete the job. Any help would be greatly appreciated. Here is what is done to the Jeep. 4" Short arm kit 1" body lift 1" motor mount lift (Brown...

I was doing some research on aftermarket trans.pans and I found a thread that implied the '06 had an improved pan already on it. However, when I compared what I had on my '06, it fit the description of the old one. Anyone else have any information on this. Copied from this thread -...
