:laugh: i can't imagine the people who run 35's on emDaffyXJ said:Yeah, The larger diameter tire is rolling a farther distance for each turn of the transmission. The VSS & output shaft sensor report that the tranmission is working harder and down shifts to third. What ends up happenening is the TCU and ECU keep the transmission hunting for gears. It will drop into and out of overdrive with the slightest change in grade of the road.
