C6. Its the only trans that will last behind 35" tall tires for a Ford that will just bolt-on, and you can score working ones for about 300.

Do some craigslist searches they always have them.

What ratio do you have?

There are no easy OD solutions for your truck.

Popular question when gas gets expensive:

If you have a 9" rear axle, a whole 3rd member swap to higher (lower numerically) gears is the best answer.

replace the clutch if it needs it...leave the rest alone. save your $$ for gas. if it ain't broke, don't fix it.

Back to the original question about gears--what ratio do you have? If you already have 3.25s, the swap isn't going to gain you much. 4.11s, now it's worth more research regarding cost etc.

Also, before assuming clutch, make sure your clutch is adjusted OK, and the bushings in the z-bar aren't shot, can cause some issues

Do you have a tach and is your speedo correct?

If so, post your rpms at 40 or 50 (any number really) in 4th, along with your tire size.

Post the AXLE code found on the Warranty Plate, located on the left door face below the latch.

The Ford 9" axle ID tag is under one a the bolts (if it's still there) that retains the carrier (pumpkin) to the housing at approx 5 o'clock. The tag has the ratio stamped on it.

Ed: No factory tachs until 1980, and most a these trucks are using fat P-Metric radials. So none have accurate speedos, cuz the original tires were skinny bias ply G-78 x 15's or 7-75 x 15's.
