Re: Transmission wont shift to reverse
if you hear a whining noise, that means that your pump is not pumping enough fluid causing that whining noise. so that means your line pressure is to low to operate the transmission properly. how many miles on the truck? have you ever changed the tranny fluid? it could also be a clogged tranny filter, or a clogged EPC solenoid in the tranny. you can hook up a pressure gauge on the driver side of the tranny and read if the line pressure is with in specs....
