Tranny Issue

Can anyone help to decipher these codes? Car jumps out of gear/tranny slips and I have to restart the car to get it to move. After about 5-10 mins. of driving it stalls again.

Looks like RPM sensors are failing, incorporated into conductor plate which needs replacement. Part # diagram is from comparable vehicle, suggest pulling # with VIN.

I am not affiliated with these guys but I came across this from prior research. Could be a good option for your situation. However, your codes do not appear to be on their list.

there are two speed sensors one is a repairable job the other rarer failure is not fixable (or wasn't as of a few years ago) - it is safer to fit a new one... they are vastly cheaper than they once were... but it is linked to the immobiliser and Merc don't like to sell outside main dealership - plenty on naughty software out there lets naughty people swap data over - I would never bother with a repair myself

it won't be the cause of the slippage issues - if its a V12 you need an overhaul - they only last a few miles if you open the throttle

Found a leak at the Trans Electrical Connector. Replaced connector and all is well.
