Try 4,800 miles
Just got word that my torque converter went out at 4,900 miles. I jinxed myself because I've been bragging to everyone how much I lover my Challenger (even if it is a V6 automatic). The check engine light came on and my gas mileage began to fall so I knew something was up. The shifting felt odd to me from day one but I just thought it was the way the Challenger's shifted.
