Hey guys. I posted this on another forum, so if you've replied there, Thanks! If not, give it a shot.
I'm sure some of you have seen my various posts related to the shudder in my Jeep's drivetrain. Two dealers seem stumped, and the "rep" suggested that a lot of people have been complaining and nobody has a fix or knows what the issue is. In an attempt to not get swept under the rug and shafted, I'm taking it to a 3rd dealer tomorrow. Here's the skinny...
2011 5.7L Jeep (June 2010 Build Date) symptoms:
1) Between 45 - 70 Mph, the jeep will shudder/miss/wobble (something?) when maintaining a speed, especially up embankments. My word would be shudder.
2) The RPMs do not change a noticeable amount per the tach.
3) Recently, it will also do the shudder when slightly accelerating (not requiring downshift) for 2-3 mph.
4) It appears to only do this in OD. If cruising, the shudder stops when it gears down. When using the manual shifter to see the gear, it's in 5th - so I assume it's shifting out of OD. The RPMs appear to always be under 2k when it happens.
5) ALL PCM, software, hardware, TSB updates have been applied, including the HEMI shudder issue.
6) When accelerating from a stop or just giving it hell, there is no weakness or shudder.
Dealership "Fixes" already performed:
1) TSBs
2) Torque Converter replace (dealership#1)
3) Additive (dealership #2)
4) MDS harness replace - swinging in the dark, I believe.
5) Only running 89+ octane fuel - no impact at all.
6) New driveshaft
All plugs and general items have been addressed and cleared. I have an appointment on the 10th at Dealership # 3 with the transmission tech as I think it is related to the OD gear.
Any suggestions, fellas? Any word of other issues with the 5spd? I think the rep was just blowing smoke as I don't recall significant issues with the transmissions on here or in the prior model years, especially since it was not the case earlier. Just trying to go in with some "hopes" for the third dealership.
