Trying to trade in my 06 RTL in on a 2017 and the dealer is saying I have a transmission that stutters and a front axle that is popping. At 215,000 miles he says that both issues make my truck on it's last leg. Anyone know what may be going on with my truck. I have driven it from near Nashville to Knoxville every week for the last 10 years and had no trouble. Is it about to die on me?
