Helen & I flew to St. Louis Saturday morning to pick up a 2006 RD Ltd with 85k on it. During the road test on I-55 before we actually bought it, I tried desperately to load the TCC and get it to hiccup but t was rock-solid, accelerating under heavy throttle with TCC engaged in 5th. So...we headed home down I-55 to Louisiana and 306 miles into the trip, on a hilly ascent the engine revved to a higher RPM, the CEL came on.

When I realized that the trans was still sending power to the wheels I quickly figured out that the error must be a slipping TCC. I pulled over to check things out but nothing out of the ordinary going on under the hood. Firing back up and accelerating onto I-55 as soon as TCC engaged the engine revved again so this time i shifted to neutral, cycled the ignition and feathered the throttle allowed TCC engagement and drove the other 400+ miles like that. Occasionally the cruise would over-power the TCC and it would go to limp mode again but now I left the trans in gear, cycled the key and picked up TCC again with a light throttle. We made it home OK, but I am afraid I may have sent shavings through the trans although it still shifts fine, maybe a flush, filter & fluid during TC replacement will suffice. The selling dealer, South County Dodge Chrysler Jeep gave me a bit of a warranty but only if they perform the work, we are twelve hours away so I will ask for TC only and I will furnish the Labor. I will let y'all know how that goes.
Good Luck with your situation Greg, I hope someone above the rep authorizes the dealer to replace it, we all know, it will fail.
