Fault code 2783 (The friction power of the torque converter lockup clutch is too high)

[Slartibardfast1]

While out for a drive yesterday, cruising steadily at 70mph, I felt a slight "jolt" (sort of like a lumpy gear change - but it wasn't) which happened again after about 15 mins.

This morning I connected the icarsoft and it showed a (Transmission) code 2783 - State current: "The friction power of the torque converter lockup clutch or of the wet start-off clutch(NAK) is too high"
I erased the code and went for a drive. All smooth. Checked icarsoft on return which showed no faults.

Is this something I should just keep an eye out for, or maybe get it checked out by a specialist?

Car is 2011 S350L Bluetec (W221) 3.0 Diesel with 61,000 miles. Serviced on the dot every year by Main Dealer, including Transmission service 2 years ago.

Thanks in advance.

Mercs rarely throw up fault codes for no reason.

Keep an eye on it - or a feel for it.

Then go from there.
