C-4 transmission won't shift into 3rd gear
Hello everyone! Hoping someone might be able to help me with my transmission problem.. I have a 1966 Ford Fairlane, 302 ci motor, and C-4 Trans. I just finished up buiding up my motor, and took it out for a drive, and it wouldn't shift into 3rd gear! 1st and 2nd was no problem, seemed normal, but 3rd never came. Even when i went trough the gears on the column, still couldnt upshift. Not sure what the problem is.
Checked my kickdown cable, wasnt stuck; that vacuum tube from my manifold, and i assume goes to my transmission, wasn't kinked or anyhing. Not sure what this vacuum line goes too. And the fluid level is good.
Any information would really help me out!
