Some customers may comment on the SES light being illuminated and a chuggle or surge being felt when driving at higher speeds.
Technicians may observe on the Tech 2 , an excessive torque converter clutch (TCC) slip speed and DTC P0741 set as Current or in History.
This condition may be caused by seal damage that allows the TCC apply fluid to leak into the channel plate, causing excessive TCC slippage under certain operating conditions, eventually resulting in a total loss of TCC apply fluid pressure.
The TCC may have partial apply fluid pressure or no apply fluid pressure. If excessive slip speed is noted on the Tech 2 and the condition/cause cannot be corrected by using the DTC P0741 diagnostic information, then worn seals from slippage of the drive sprocket bearing inner race on the drive sprocket are indicated
