My 2006 Sport with the 42RLE has been plagued by the PCM issues commonly found in 2005-2006 TJs.

Had the original PCM “rebuilt” a few months ago, which did absolutely nothing. CEL returned immediately.

Installed a PCM that I purchased from FS1 about a month ago. Drove 40 trouble free miles prior to heading on a 300 mile one way trip into the Sierra Nevada mountains for a wheeling trip this weekend. Headed out of camp Saturday morning and the rig would no longer shift past second gear. Hit the trail and put the gear selector into first gear. Rig wouldn’t hold first gear and would constantly shift into second gear. Then the CEL illuminated with a bunch of codes I’d never seen before. Not the same codes that were constantly present with the original PCM.

Thankfully I brought the original PCM with me on the trip. Swapped the malfunctioning FS1 PCM out and continued on the run.

Going to make a warranty claim Tuesday morning with FS1. Hopefully they can send me a PCM that works properly.

I will update the thread with the results of my warranty claim. If they send me a replacement PCM I will also update the thread with functionality results.

Sure sounds like a bad one. Hopefully they will let you know what happened.

Bummer. Hope FS1 stands behind their warranty without a hassle. Please keep us posted. Just read on another forum/thread where an FS1 PCM crapped out. Watching the warranty process on that one, too.

Good luck.

Thanks for the words of encouragement. I can deal with broken axle shafts and ujoints but this PCM issue is nonsense.

Started the warranty process with FS1. Customer service indicated that they will let me know tomorrow about the next course of action. Hopefully they will honor their warranty and send me a PCM that actually works.

Even better, maybe you will be the first one to have this problem permanently fixed. The only real fix on another forum was an engine and tranny swap. Good luck.

Still haven’t heard from anyone at FS1 after submitting the required warranty claim paperwork. Was supposed to hear back today. Will update this post daily.

If I can’t get the FS1 PCM to function properly I will buy a PCM from wranglerfix. If I still can’t get the rig to operate properly then I’ll strip the rig, sell the after market components, then send the carcass to the junkyard.

I already built a YJ to replace this rig. Just need the TJ PCM to function properly so it can be smogged and sold.

Reports about the Wrangler Fix PCM have been excellent. THIS could be the permanent fix!

Never received any feedback from FS1 about my warranty claim. Called them this morning and was told I would receive a return shipping label no later than tomorrow morning. Marginal customer service as they consistently over promise and under deliver.

“Marginal” is not the word I would use.

Never received the return shipping label as promised. May have to file a charge back with the credit card company. Already spent over an hour on hold this week waiting to speak with someone at FS1.

There have been successful reports on the Wranglerfix, but every one I have seen is from a new member (less than 50 posts)...

I would file the claim. It doesn't matter anything about the company, fix, or anything. If you contacted customer service and they provided a timeframe, which wasn't honored, you need to protect yourself.

Ok, I'm not the only that noticed this. The slew of PCM threads/posts popping up from new accounts.

Thanks for the heads up on the newer member posts. This entire PCM issue is a joke.

Are you suggesting that Wrangler Fix is “planting” the positive reports? I really don’t think that’s the case. If so, I don’t think the owner, Mark Cantrell, would make himself so visible and accessible. FS1 hides behind a call center. Mark Cantrell answers the phone every time. Get your money back from FS1 and give WF a shot. I really think they are the real deal.

Good luck.

Welcome to Wranglerfix.com
The only proven fix for the 05-06 TJ Wrangler PCM!
The PCM comes with a 1 year warranty.


Not very confident in their "only proven fix" or it would come with a lifetime warranty IMO. It must be a proven temporary fix.

Time will tell on the Wrangler Fix product. But, even a lifetime warranty is worthless if you don’t stand behind it.....read Blort’s story here and elsewhere.

I'm not very tech savvy but I believe the owner of this forum is able to check ISP addresses and identify multiple user accounts from the same address.

Monday morning update. Still haven’t received the return shipping documents from FS1. Was promised the documents no later than last Friday morning. Going to pursue a chargeback with the CC company today.

Filed the chargeback with my credit card company. Still haven’t received the required paperwork from FS1 to return the defective PCM. Not sure what the deal is with FS1 but I no longer have any confidence in the organization.

You’ve been more than patient with them. If you get a PCM from Wrangler Fix, let us know how that goes. Good luck.

Day 8 Update:

Still have not received the necessary documents to return the defective PCM to FS1. Ordered a PCM from wranglerfix this morning.

Wouldn’t be surprised if FS1 sends me a replacement PCM once they dispute my chargeback but I can’t wait any longer to get my rig up and running.

I will post some comparison pics of the two PCMs and let everyone know how the wranglerfix PCM functions.

I’ll absolutely follow through to the end. Quite disappointing that many of us have non-functional rigs due to computer issues. At least with the OPDA issues inherent to the later year TJs you can swap in a new camshaft in an afternoon of wrenching. This computer nonsense is a joke. After 26 years of CJ/YJ/TJ/XJ ownership I’m actually considering building a solid axle 1st gen 4Runner. Can’t handle any more of these reliability issues.

I REALLY hope the Wrangler Fix PCM does the trick for you and you learn to love your TJ again!

PS One of the reasons I enjoy my ‘65 VW bug is there is no damn computer! It’s such a simple and well designed machine.

Day 10 Update:

Still nothing from FS1. After submitting the warranty claim 10 days ago and speaking to them multiple times I still have not received the return shipping documents required to swap out the defective PCM.

Wranglerfix PCM should be on the way soon.

That’s really unbelievable. Hard to understand how they stay in business. I predict you’ll be very pleased with your Wrangler Fix PCM.
