Discussion:
No forward or reverse

The transmission on this truck quit working while driving. Everything on the truck works fine but the tranny. It has no forward or reverse. It is not sending power to the solenoids. No fuses blown. We switched relays. We also checked the diodes with a meter and they show good. With the truck running
the ! symbol in the dash is flashing 6 times.

I should have posted this earlier. We changed the relays
and that fixed the problem.

even tho they tested good you might want to try a new one we had a similar problem. also might want to check wiring inside the relay bod to make sure every thing is connected. i would also change the relay to make sure there arnt 2 bad.
