Here's the STAR Case referenced above (post #88):

Case Number: S1118000038
Release Date: 02/21/2013
Symptom/Vehicle Issue:
Surge Or FishBite (Tug-Pull Sensation) Sometimes Felt On Smooth Roads Between 40 - 80 MPH Accelerating
Discussion:
Some customers may voice a concern that there is a Surge or Tugging (tug) or even a Fish-bite like condition that they are experiencing. These customers typically complain under specific conditions (Transmission in 4th or 5th gear with the torque converter locked, vehicle accelerating with the engine under load, and vehicle speed between 40 and 80 MPH.
New PCM Software is in development as is tentatively timed to be available by July, 2013. This Software will be applicable for 2011, 2012 and 2013 Model Year Vehicles.
Recommend that these Customers use 89 Octane as their fuel. This condition is significantly reduced with 89 octane fuel.
The Owner Manual does recommend 89 Octane fuel for best performance.

on V6's

When my rear drive shaft failed and was replaced this also seems to have taken care of the transmission issues I was having around 2000rpm. Trannie shifts a lot smoother and doesnt hunt or surge. All I know was the driveshaft was replaced. Not sure what esle was done when the dealers had my 2012 GC. Driveshaft began to go at about 11K miles.

Wow.. I've had this issue for 2 years.. and now our proposed release date is July 2013. If I keep driving it, my mileage on my jeep will be over 100k at that time and I seriously doubt anyone will do the TSB without charge. I am for damn sure not going over the 100k powertrain warranty without this resolution. We own some land adjacent to the dealership that I purchased my 2011. I'm considering putting it on a trailer and parking it with a huge "LEMON" banner. My service manager has been a d**k about it anyways. The Jeep Cares representative advised me to call back in March (after the proposed release date of Feb 2013 had passed, etc) and demand that something happen.... and now I'm on hold with them - haha.

The gas thing makes no difference for anyone that is wondering. I've tried everything fuel wise - no help at all. I even bumped to 93oct for 3 weeks and still hopped all the way up hills.

I use 92 oct. and the tranny seems exactly the same as when I had 87 oct. in the tank, including the, "fish-bite". So IDK, but I hope the flash will help anyway - guess we'll find out ... !?

I believed the District Manager for Western North Carolina when he told me in October the fix would be ready in February. I believed Orlando, a customer service rep who said he is my "sole customer service contact with Chrysler Jeep," when he called in December to tell me the fix would be available in February. I believed the local dealer when he called in January to tell me the flash would be installed in February, Why would I ever believe what Jeep Cares or anybody else connected with Chrysler had to say now?

Can't blame you Butch.....who wouldn't feel that way?
If I had a similar issue & was getting the same runaround, it would definitely be my first & last Jeep.

WHy would you even try a different octane? How would the octane rating have ANY effect on the transmission? Thats a poor excuse for a fix right there. To boot, why arent you running 89? It calls for 89 and you run 87???? Probably getting a bit of KR. You get KR with the stock engine and the recommended octane. I couldnt imagine running less.

Had this same problem on my 2005 Grand which I kept for a year and sold it due to this problem. Drove me crazy. That is now a 8 year problem that I know of and still exists. My 09 Grand and now my 11 Grand will act up on 87 octane but runs much better on 89 octane. My wife's 08 Liberty had this problem and her 2012 Liberty does not so I gather it is fixable and it runs on 87 octane. Just to compound the issue my 07 300C did not have this problem at all. Must be a Jeep thing.

So I sent Chrysler a certified letter documenting 3 dealer visits and requesting assistance under SC lemon law. Chrysler responded that they have spoken with the dealer and determined that the vehicle is operating as intended and they consider the case closed. Goodbye Jeep Hello Toyota. I refuse to be frustrated by this issue for 4 1/2 more years. Best of luck to the rest of you.

Has this issue only been with the 5.7 liter motors, not the 3.6?

I don't know what the proper procedure is, but I wouldn't be contacting Chrysler for assistance in lemon law on the vehicle they built. They did exactly what one would expect them to do. Unless of course sending them the documented letter asking for assistance is the first step required. Are you pursuing other avenues to get the ball rolling? I'm assuming your state should have a website in regards to how to pursue this. Good luck.

I have been following this post for months and I guess I am lucky I do not have this condition. If I need a downshift I gently press down and it shifts down and goes. I have no tugging or fish bite. I guess this is a small percentige of owners with this but many are upset, and I understand. I use 85 Octane fuel and have the Hemi. In mountain driving this thing is great, shifts perfect. I now have 22K on a 2012 and really enjoy the truck. Sorry for all those with this problem. I can't figure out the difference between trucks.
