I have mercedes E240 1998 model. Problem is my raidiator rupture and water mixed with transmission oil. I have overhauled the transmission, Reset computer. After driving 1 day my car stop reponding when moved the gear to D or any other position. If I switch off the engine and restart the engine after one minute gear will engage and car move but again it will stop.

Can any any advise what may be the cause.
Primary pump, valve body, clutch plates replaced even electronic control unit is changed.
