I Have a 2006 Commander 2wd 3.7 L. with the check engine light on. I took it to Advance Auto, they scanned it and said Code P0700 Trans control malfunction. And Uo404 Invalid data recieved from control module gear shift. Anyone have this problem or know how I can fix this problem,Please let me know. :bowdown:

The trans acts funny going about 30mph let off gas just coast then get on gas abit and let off and the trans acts and sounds like it shifts into low gear,when you let off gas the RPM's go up and you can feel the torque like it shifted into low gear.

Now when in drive all the dash shifter lights are on P,R,N,D,O/D all are lit up, should and use to be just the gear you are in is/was lit up.

Jeep is 2 months out of warranty.:grim: :(

I take it to the dealer when the check engine light comes on and of course by the time i get it there the light has turned off and they say they don't know what to do.

Accepted Answer
Hi Brad,

This is a rather common problem, I'm suprised they are having trouble diagnosing it.

Your jeep has an electronically controlled transmission, with 2 computers.

transmission control module - does all the shifting, etc..
electronic shifter module - located down in the shifter assembly. basically all it does is relay what gear your in to the transmission control module
95% of the time it's caused by the electronic shifter module not relaying the proper information to the transmission module. That's why your display gets wacky, as the car doesn't know what gear your in. Make sense?

The fix is to replace the electronic shifter module. Hopefully your still under warranty, as they are quite expensive, for what they do.

This problem will store a code "implausible data recieved from electronic shift module". Even if the car is back to normal operation, and the light has turned off this code will be stored in memory. If it's acted up recently (say last 300 miles or so) and nobody has erased the codes, I'd try another dealer, they should have no trouble diagnosing it.

I hope this helps answer your question, if so please click accept. If you need more information, don't hesitate to ask!

Thanks,
Leo

From www.check-engine-light.com/jeep :

Question: Hello, 2005 6cyl jeep grand cherokee. 15,800 miles. check engine light stayed lit-up when i started car. next morning was normal. 5 days later,stayed lit-up again. jeep was 4 weeks past orig.3yr warranty period. took to dealer and they ran diagnostic test. fault code was u0404. said i needed to replace shifter/electronic control module. since it was past warranty, it would cost me $657.00. i said i'd let them know. called jeep to find out if they would help on cost to replace. jeep talked to service manager at dealer and manager told me they would replace for $190.00 as per jeep. offer is good for 30 days. engine light has not stayed on since i told dealer i'd let them know which is now 22 days. should i believe i neeed to replace module and accept offer? thanks - Ron, September 2008

Answer: Hi Ron. The description for a U0404 code is Invalid Data Received From Gear Shift Control Module. Since a Jeep factory-trained technician has looked at your specific problem, given you the code and diagnosis, I'd say, YES, definitely take them up on the offer and get it fixed. The reality is if you don't fix it now it may wind up costing you the full $657 a year from now. Do you see what I'm saying? I guess the other option would be to take it to a different shop and get a second opinion. But honestly since they've already looked at it and are willing to give you a discount on the repair, I say let them do it! Thanks for the question.

you may want to check with the dealership...this may be on eof the problems that called for the recall for the tranny to be reprogrammed.

The Commander has been sounding funny recently (lifters, or normal HEMI sound I thought) and when I went for the oil change they looked at it, but didn't find anything. I figured it may have just been the Commander being jealous of all the attention my wife's new (to her) baby Wrangler sibling has been getting - and that it would get over it soon. No biggie. And then...

Today, I went to go see the fireworks and as I was backing out of the driveway, the transmission hesitated and then caught, but when I went to go forward, it was responding very sluggishly. I noticed that the transmission was stuck in 3rd and wouldn't go to anything else. After the fireworks (just a few miles away), I started it up and as I pulled into the long line to get out of the parking lot, it stalled out. It restarted fine, and actually seemed to run better (and was in "D" instead of "3" the whole time).

We just got home and I ran the DTC code and picked up the P0700 - the Transmission Control System Malfunction. I searched and found that others have had the same issue, but I don't recall seeing whether changing out the Module actually fixed the problem - or how much it cost. I'm taking it in on Monday.

Is the module something most Chrysler Dealers would have in stock? Is it used in other Chrysler vehicles? How long should I expect it to be out of my hands?

I replaced the ESM / Shifter bezel and No more problems. Check engine light is off and No more codes. The STEALERSHIP wanted $416.00 for the ESM/shifter bezel. I bought a new one from a Mopar Dealer on E-Bay for $189.00 + $ 9.95 shipping Brand New in the box 12 month 12,000 mile warranty. Seller has now uped the price to $319.95 + $9.95 shipping. I got a hell of a deal.

I had 2 codes P0700 & U0404 = Invalid data recieved from control module gear shift = ESM Shifter Bezel needed to be replaced. I replaced it 2 days ago and check engine light is out and trans shifts correctly now,No more codes. I have the 3.7L.

Yours is probable something differant since you dont have the U0404 code. I know the 4.7L have had alot of problems with the TCM trans. control module,There is a TSB out on them and I belive a recall also,but could be wrong on the recall. STEALERSHIP had to reprogram them.

If you dont get the answer here go on Jeepforum.com search for and ask Merlin Tech He is a Jeep Master Tech in the UK. You might get the answer right off of Jeepforum just post and see,if not Merlin Tech will know the correct answer.

Not looking good... the dealer picked up the P0700 (Transmission Control System Malfunction) plus P0876 (UD Pressure Switch Rationality) and P0736 (Reverse incorrect gear ratio). I guess its backwards and irrational - at least I know I need a female name now. =)

The dealership is dropping the pan and looking for some transmission filters that may be split (apparently there is a TSB for it). If they are, they will be replaced, if that isn't the issue, they will have to tear apart the transmission to look for burnt clutches or something like that. Regardless, it sounds like a bitch.

Happy to have my MaxCare Warranty right about now. If it goes past Wednesday, the warranty covers a rental for five days too. Bonus! I didn't even know that was in there.

1st code is primary.
2nd and 3rd codes are resultant.
Till primary code is resolved chasing resultant codes is a wast of time.
I don't dispute the T.S.B. for the cracked filters though.
That one has come up over and over on the forum.
If the clutches are burned (because of the filter allowing air into pump) the pan will have much clutch material at the bottom.
Then trans would have to be reconditioned before any more diagnosis could take place.
Usually though, the cracked filter case shows itself as delayed engagement, usually reverse.
Did your Jeep display any odd behavior before this occured?

Just asking to add to my and the other readers info,
Rob

The only strange behavior happened immediately prior to the code - I tried to go in reverse and it hesitated and then jerked into gear.

Although, I have noticed that over the past few weeks, it doesn't seem to have the same power at idle as it used to. I used to be able to throw it into Reverse and it would begin to move down the driveway - recently, it just sits there until I give it some gas.

A couple of years ago I had the same problem, but I could not use the gear select. I believe the dealership did replace the shifter control module.

Now, I noticed every time I put the key in and turn it on the message appears for a split second.

I have not noticed any problem, but should I worry for any future problems?
