Now you are telling me there is trouble codes. Withholding information means we are not going to get to the cause of the problem. D4 light blinking indicates a fault has been detected.
P1768 is a fault with the Liner Soleanoid which is one of the main solenoids for transmission geat control.
If the problem occurred only after replaement of the rear main seal, it most probably means the solenoid had been damaged during transmission removal/installation (quite often happens when job was not done with care) or the wireharness is not connected correctly.
