2005 Wrangler - Jeep Says Computer is Fried, but they Cannot Provide a New One?

How the heck is it that they stop making parts for a 2005 car?


They (Jeep Dealership) said they can send it off to be rebuilt ($1,100) but it will have no guarantee.


Anyone else have this problem, have a solution?


Thanks in advance

05-06 used a new design PCM(computer that failed so often chrysler Jeep) ran out of replacements and dumped their wait list

Your choices if it truly is pcm is flagship one or wrangler fix

There is lots of posts look for 06 automatic PCM as search terms

My FS1 PCM failed within the first 300 miles. Still in the process of making the warranty claim without much luck.

Some good feedback from others that purchased a PCM from wranglerfix.

Had my OEM PCM rebuilt. Still didn’t function properly. Purchased a PCM from Flagship One and it failed within 300 miles. PCM took a dump on the trail but thankfully I had my original as a spare.

Wranglerfix sounds promising but keep in mind there is no long term data related to the quality of these PCMs in our rigs.

Engine swap or parting out your rig may be the only viable options if you can’t find a functioning PCM.

I had very good result from FS1 although took 2 tries and a couple months

That NGC PCM from either place is still inherently flawed and best avoided by avoiding 05-06 TJ all together

Neither is giving you a PCM that was not an oem chrysler product with the inherent NGC failure prone design

JTEC and JTEC plus we’re just a better more reliable PCM

Glad this was brought up, I was considering selling off my 1997 Sport and moving up to a 2006, I don't want something Jeep has given up on.
Guess my next vehicle will be a Chev Tahoe.

The computer issue is unique to the '05 and '06 models, especially the ones with an automatic transmission. Previously there was an ECM for the engine and a TCM for the automatic. In 2005 they merged the two and it has issues, primarily with cold starts.

Earlier models (up through '04) you can find the computers on ebay and in Jeep specialty yards. Some will go bad, but not at the rate the '05 and '06 do. All manufacturers can have a limited amount of issues with the computers, even the Tahoe.

Just get the Wrangler Fix PCM ($550 w/ one year warranty) and don't look back. Many of us have been pulling our hair out for a long time over this issue. Wrangler Fix seems to have come up with a unique solution.

Hope springs eternal
Seems they figured how to reprogram pt cruiser 04-05 pci to work in TJ but still same failure prone NGC Chrysler pcm just lots of them available cheep and makes for a huge reprogramimg price
Not around long enough to see how they last but they are all pretty old and manufactured with an inherent heat sensitive flaw

Best bet is buy a PCM from FS1 or the other guys and sell the poor designed pcm Vehicle to someone else and buy an earlier year TJ

forgive me for not being more educated on this issue.............but why can't we use any PCM from any older TJ that's about to be junked?

or they don't make any other vehicle that came with a straight 6 and that auto trans?
this sounds like it should have been a class action suit.

2005 Wrangler - Jeep Says Computer is Fried, but they Cannot Provide a New One?

First you cannot legally use older emissions equipment on a newer vehicle

More significantly the 97-2004 TJ
The 96-2000 xj
And the 99-2004 WJ
AKA the vehicles that used the 4.0 and were OBD2 except the 05-06TJ
Used JTEC or JTEC+ PCM
Only OBD2 4.0 that used the flawed NGC PCM was the 05-06TJ
That NGC next generation computer was flawed and failure prone

In 2005 the emissions regs had a major step up
Which is why many vehicles did a complete redesign for 2005
New Grand Cherokee for 2005 new Durango/Dakota for 2005(although durango was done in 2004) New mustang new Subaru legacy/outback all with CAN bus

But for the TJ they just did a whole bunch of poorly designed half steps to get by as 4.0 and TJ were both to be soon replaced forever
Hence crap like the PCI bus NGC PCM
The gas filler that never worked and the new failure prone cam killing OPDA all gifts from Jeep to squeak by on minimal cost to half ass meet the new emissions with minimal investment in a obsolete vehicle and engine

BEST to just avoid the 05-06 TJ

OPDA = Cheap and easy fix
Gas fill overflow = Cheap and easy fix
PCM = Not so easy fix, but Wrangler Fix (and maybe FS1) seems to have found the solution.

I love my auto ‘06 and plan to keep it for a VERY long time.

Reprogramming flawed pcm that have same failure prone design flaw and just have not failed yet is quite a bit short of a real solution

For some of us you are preaching to the choir.

As for @Digger84 , he is so invested in his own negative opinion of all 05-06 TJ's that all he hears when someone suggests that the issues can be resolved is bla, bla, bla.


There are issues with all model years. Address them and move on.

Check out the replacement PCMs for 05-06 Wranglers at www.wranglerfix.com. So far I've seen nothing but praise from those who have installed them. They have even apparently fixed the software/programming problems the version for the 42RLE transmission the factory PCM has.

2005 Wrangler - Jeep Says Computer is Fried, but they Cannot Provide a New One?

Once they have been around a little while without name change and reforming
Once they have been sending them out for long enough to establish any longevity
Once they actually give a straight answer to what if anything they are doing beyond reprogramming other Mopar NGC oem PCM maybe they can claim to have fixed something

But all the name change,spin and subterfuge leaves me doubtful as no company can legally alter emissions equipment software or hardware on a street legal 05-06 vehicle without EPA approval

We know what FS1 is doing with one name and a long history
pCM -gods aka wrangler fix not so much

"Welcome to Wranglerfix.com
The only proven fix for the 05-06 TJ Wrangler PCM!
The PCM comes with a 1 year warranty with an additional year available for $75.00".


Not very confident in their abilities for a proven fix or there would be a lifetime warranty IMO. Proven PCM fix =

so what i think i see is you could use the PCM from the 04 and previous models, but it becomes a trailer queen as it won't pass emissions/ inspection for plating?

or roll dice on a re-fixed.

To use illegally would also need complete new wiring harness
A new crank sensor with special flywheel
A new external transmission control module
A new air bag module
An earlier version of the oil pump drive assembly
And deal with any skim issue

Or get a 6 speed. I've had two 05' 6 speeds and zero issues. For an auto, I much prefer the 02' and older 32RH trans with no overdrive.

IDK i'm tryin to sort through this.

all 05-06 are prone to this? just automatic's? whats the % of failure been vs production less than 20% more than 40%?

I don’t know the % of ‘05-‘06’s automatics with the hard shift issue, but feedback on the Wrangler Fix product is 100% positive so far. Even Jerry Bransford is impressed. Digger84 seems to favor FS1 which puzzles me when I’ve been reading a thread started by Blort.....his FS1 PCM just crapped out on him after just 300 miles and they are dragging their feet on their so called “lifetime warranty”.

Because truth beats games and name changes are not something a quality company does and FS1 has Been around for years and did right by me on a NGC PCI PCM
Jerry has newer bought a PCM from either of them
