Just got off the phone with the dealership after bringing it in for a shuddering feeling under moderate acceleration. Was told the torque converter was the culprit. My st has 49,9XX miles on it so thankfully covered by warranty. Bad news is a new one is on backorder and was told it could be 1 week- 6 months. They are giving me the car back to drive as it is not super severe but I am worried this will cause other problems with the trans and if it does would they blame the issue on driving with the faulty part and not cover additional damage. Anyone else have this problem? I'm bone stock besides wheels, catch can x pipe and valvetronic mufflers.
