My Nitro has been in the shop for the last 2 weeks. This is the 4th time! A technician from Chrysler came to the dealer to look at it and test the transmission , torque converter, and the drive shaft. It looks like the drive shaft is bad, so he says. I have already had the torque converter replaced. The dealer has to wait for the O.K. from Chrysler to fix it. Hard to tell how long that will take. It still doesn't explain why the ABS/ESP lights come on and stay on sometimes. The transmission still has the shudder. I'm ready to trade!!!!
