My 1957 Owners Manual says to "release the accelerator" to shift...nothing about using the clutch...did that change in the 60's?
I've been driving electric and vacuum shift for 20 years and I never use the clutch...

The '62 GMC 6500 that I used to drive starting back in '71, had the 2-Speed Shifting Instructions as well as the Shifting Sequence attached to the Visor by the Factory, which stated to always use the Clutch. Since that truck, I drove many more that also had the same type instructions. I learned that way and never changed. Not sure about anything in the 50's. I never drove anything that old with a 2-Speed, lol.
I know it's possible to shift one without the Clutch and I sure have, but always like how it shifted by using the Clutch, especially in the lower gears. I also believe that it is not as hard on the drivetrain as well.
