Hi all
I have an 81 F150 with a 4 Speed Manual transmission. I had the transmission fluid pumped out of it and filled with new 80w-90 fluid. Now I have no reverse. It shifts without grinding or anything, but doesn't move. First still works. I thought about linkage becoming disconnected but the linkage is evidently inside the transmission as the stick shift goes right into the back of the transmission with no visible linkage. Has anyone encountered this before, and how do I fix it?
Thanks Ros
