Ok so I just returned from the dealership. I said nothing. They took it straight into the garage and hooked it up. 20 minutes later they tech came out and said my computer detected torque converter chatter. He then proceeded to inform me that there were 2 TSB's for this issue. My computer was flashed with the new software. I drove home vibration free. However I never got it to kick into 4th, so tomorrow will be the true test when I get onto open highway.

However, I was informed to give the computer 300 miles to re-learn my driving style. If after 300 miles the vibration returns, I'll need re-flash, and the torque converter replaced. I'm also left with piece of mind my dealership is pretty cool. They hooked me up on parts, and appear to have nailed this issue.

Thank you guys for all your time and help. I appreciate it.

Hey thats great news, it been 3 days since I left the dealership with the same problem. if I drive with the O/D off I have no problems, but with it on and especially when the tranny is hot it feels like the motor is bogging down. I'm goning back, heck my Jeep is brand new (1200 mile) I shouldn't have issue like this.
Thanks for all the feedback.

Be sure to print out the 2 TSB reports and show the dealer you want that service done. I'm positive that's what you're experiencing. You described the exact same symptoms I was having.

I drove to work today, 60-65mph with no issues as of yet. I need to check my transmission temp though on the next 60 degree plus day we get and see if it's still running hot. It's not hot enough to hurt anything, but I'd say it's above normal operating temps.

Inform the dealer of that as well. They'll install a temp gage and/a warning light. It slipped my mind to ask them about it since I was so excited I wasn't tearing the slushbox apart lol!

Thanks and me too inferno. Even if it returns I'll just get a new torque converter. No big deal.

I think anyone with a JK, should probably add an aux tranny cooler as a future mod if you've got an automatic. A $150 cooler is better than a $2000 transmission lol! And you know if it's going to bomb out on you, the warranty will be expired.

I assume something went wrong with the convertor lock out strategy..In O/D the convertor needs to be locked out..If not, temps will go way up and indeed the convertor might act funny..the vibration might be caused by some cavitation.... ( too much slippage)

Now without any accent in Flemish/Dutch......

Ik vermoed dat er iets verkeerd gegaan is met de converter lock out.. Als ge in O/D zijt moet die "locked out" zijn. Indien niet, zullen de temperaturen in de converter oplopen en kan de converter beginnen aardig te werken.
De vibratie kan een gevolg zijn van cavitatie, te veel slip..


I feel much better now...

Keep us posted.. this is good feedback..

Do a DTC test yourself.. I believe you turn the ignition key to ON, then keep on pushing the key into the ignition cylinder, this to exert pressure in the mechanism. Then turn to OFF (keep pushing the key) then to ON (do this rapidly) and the third ON time the odometer changes to 6 dashes.. If a DTC is set it will show after the the dashes appeared..
In the vent you have a DTC, this will give you some discussion points with your dealer..

I could have been more precise in my previous post.. the ON-OFF cycle needs to be done three times and the third time you are in ON..

Torque converter

Well at 28000 miles, the torque converter finally went out. I took it to a different dealership for repairs. Thank goodness for the extended drivetrain warranty.
