water flooded river, can this have any effect?. is there other possible explanation for this
automatic gear transmission failure beside the gearbox itself? What must i check before i
rush ti have the expensive gearbox changed??
Not much to check,exccesive water to the tranny when hot may have hurt it.
Driving with the transmission submerged in water can cause the water to be sucked into the transmission. Drain the fluid to see if it has water in it or look on the dipstick and if the fluid is milky of frothy it has water in it. Water inside a transmission will ruin it pretty quickly. Also some of the electric connectors may have moisture in them causing issues.
Transmission control module is located in the passenger side floor area. It is prone to damage if there is water intrusion.
