Condition
Some customer may comment on the SES light on and a chuggle or surge. Diagnostics may show excessive TCC slip speed and DTC P0741 will be current code stored.
Cause
Seal damage may allow the TCC apply fluid to leak into the channel plate, causing excessive TCC slippage under certain conditions, eventually causing no TCC apply.
TCC may have partial apply fluid pressure or no apply fluid pressure. If excessive slip speed is noted and condition/cause cannot be corrected by using DTC P0741 diagnostic chart, suspect worn seals from slippage of the drive sprocket bearing inner race on the drive sprocket.

Replacing the TCC Solenoid is the most common fix and requires about 8 hours and special tools.
