My auto tranny F4A51 will not engage in any gear. I here the solenoids buzzing for 8-10 sec then nothing. My error codes ar P 0760 & P 0765 Solenoid malfunctions. Either they are hung up on a sticking valve or there is a nother signal the transmission isn't getting to place the valve in the c correct position. Is there any way without removing the transmission to see whats going on in there?
