It's supposed to go to the next lower gear. If you're in top gear (5th) it sould downshift to 4th unless you hold the lever to the left. Each tap to the left will take you down one more gear. Each tap to the right, up one gear. It will not shift if the RPM range is not OK for the gear you are calling for.

SilverMiner 53K miles on my 2012, and still no ticking ... I will have to trade it in before I hit 100K if it doesn't break I think.

Its been driving smooth and quiet (other than when a heat shield gives a little clack at high rpms). I did my first oil change (had just bought this used a few months back and 1 month in the dealership for repairs) and put in its first Mobil 1 oil change. It definitely idles much smoother. With 25K miles on it now it really feels like a new Jeep.

No regrets about buying a '12 expecting to need some engine work for this problem. It would have been nicer if the episode was 3 days vs. 3 weeks but my memory is short, luckily. Its just a blast to drive.

Is this what you are asking for?

It's normal. The downshift side of the shifter is WAY too sensitive, at least on my 2012, and many others I've tested and heard about.

You will need to learn not to rest your hand on the shift knob, especially when going around corners. Just a little extra pressure on the knob toward the driver, and you find your engine winding out from an accidental downshift. The worst for me was holding onto the knob at a stop sign and looking hard around to my left, checking for oncoming traffic before starting out from the stop. I still do that once in a while.

You will get used to it. I do it very rarely now, after three years of learning.

Is that because this is not a recall?

I remember receiving a letter from Chrysler about a recall (the transmission line, I believe), and it said that I have the option of getting it fixed somewhere else and submitting the receipt to Chrysler for reimbursement.

Tseg 23 Days since the CEL came on for a 2nd time I finally have my Jeep with a new left head back in my hands... 20 days at the dealership. Seems to be running fine. The dealership's only excuse is that they've been busy. Maybe tomorrow I'll search for the date code. Here's to no more Wrangler repairs for the next 200K mi.

I have my fingers crossed that when they call they will inform me they have replaced the head.

One other item... when I brought in my Jeep last time I dealt with the same Service Writer who tried to play tough guy. This time he was much more accommodating. He mentioned his business cards had not yet arrived, and he is very young looking, so I'm guessing he is a rookie trying to sort his way through all this.

I read between the lines, that's not a good idea. LOL You said "shops", I took that as you were like I am and try to avoid dealerships. LOL

GC Jeep did good by me.

The Jeep is my 2nd vehicle, drive less than 5K a year, not sure 10 year extended warranty would not enough. It's like a timebomb and I wish it goes off sooner.

Yes I know it's covered I was asking about which dealers have experience with this repair and are reliable. I have heard some bad experiences with dealers doing a crappy job on this job. I have a 2012 obviously with 42000 miles

Short answer: The second revision to the problem head improved coolant flow through the head and beefed up the valve guides.

The dealership won't offer me a free loaner even though the issue is the same. Customer Care is also being difficult about the loaner, putting blame on the dealerships. I told Chrysler they need to Man Up. I'm still on hold as we speak as they claim they are trying to locate a dealership in my vicinity that can replace my head and give me a free loaner. Overall I'm very disappointed in the dealership and Chrysler Customer Care. Lets see how they turn a negative into a positive...

Ok--- Chrysler rep did give me a case number and advised dealership will give me a free loaner (when they get one back) until engine diagnosis is done (and will do a more exhaustive evaluation of cylinder head beyond reset - I assume that means leak-down test). If it is the cylinder head, I then will be given a rental I have to pay for, but can then submit the invoice to Chrysler for reimbursement.

Meanwhile, Customer Care said I can drive vehicle with light on until dealership finds time for me. They also mentioned the dealership is currently 2.5 days behind doing basic evaluations... I suppose when the system is designed to fix the same problem multiple time on the same vehicle this is what happens.

Dealing with the car company bureaucracy reminds me of times when I've had to deal with Chinese or Russian regulated businesses. Not surprising, but painful and very time consuming.

ming Just got my jeep from the dealer yesterday 2012 unlimited sport with 27000 mi took it in a week ago with cel on dealer replaced the left side cylinder head due to # 4 cylinder leakdown over 25% everything covered under warranty per sb so far everything seems ok but i am still worried. Good thing this is just my toy and not a daily driver or else i would be trading it in i dont care how upside down i would be!.

RockyRiverJeep Yes, you can drive your Jeep around before the repairs are made. No harm will be done.

You'll only receive a rental vehicle after the diagnosis of a bad head discovered during the leak-down test. When you schedule the appointment for the repairs, the dealership should make sure you are reserved for one of their cars or usually an outside rental car company that they deal with. This way your rental car is ready for you after you drop your car off for the repairs.

I didn't have to pay for a rental car when my head was replaced in June 2013. The dealership is the one who should be submitting for re-imbursement for the rental. Unless there was a change in Chrysler's stance on this recently, I would directly press Chrysler Customer Care to make the dealership submit. IMO, it smells as if the dealership is pushing the responsibility off onto you.

Good luck.
