So I made a decision on a 1988 5.0. I am going to have to have the transmission rebuilt as it seems like it might have lock up from what I have read. Fluid is full but it feels like its shifting from 1st to 2nd and doesnt shift again until after the RPMS shoot up. I,m loosing power at about 40 MPH and shooting RPMS super high but will eventually level out and continue accelerating. I wanted a "project" well I guess I got it!! I know very little about cars so all tips and pointers would be much appreciated.
