Question type: Maintenance & Repair

Truck will not shift into overdrive even after changing the filter and fluid as well as the relay.  
Was running okay this morning then this afternoon wouldn't shift.  RPM's were over 2300
at 60 MPH.  Normally they are 2000 or 2100 at 7o MPH.  Any ideas?  It's our only vehicle
and need it for work.  Thanks

^Your governor solenoid has no bearing on overdrive or lockup. They are electronically controlled by the PCM. What relay are you saying you replaced? You are probably going to have to get a scan tool on it and see what the truck is doing. See if the PCM is actually commanding it to shift to overdrive, or if something else is keeping it out of overdrive. It could be a broken wire making a bad connection, or it could be the solenoid pack on your valve body.

Thank you. However, I did replace both the solenoid and the shift solenoid/governor. It shift alot better but I still dont have overdrive. When I did the test drive on the highway, I had no change when I used the electronic shift on the shift lever turning the OD on/off. Now I'm really stuck. I replaced the transmission relay under the hood and also the fuse that controls the OD inside the cab. No Change
