08 GP 3.8 plain jane 31,000 miles
on the interstate, 65-70 mph pulling a slight hill (not enough to kick down out of OD) I get a shudder, and I can see the speedo move with it, the tach does not move. Is there pressure building up somewhere that is not being let off at the right time and causing this? Or is it just a bad torque converter?? Or......I am getting the run-around from the dealer, so I want to go in there and tell them to check _________ and I really hope that takes care of it.
I have noticed the problem at other speeds, and then it goes away, but my wife (that's who drives it most of the time) said that it is happening more often.
Is it as simple as just changing the fluid? Because that needs to be done soon.
any help is appreciated.
