NO, I was referring to the A883 4 speed with OD. Many times people don't know how to call a transmission what it is, as in a 3 speed with Granny Low, or 3 speed with Overdrive. NO, it's a 4 speed with a granny low, and it's a 4 speed with an OD. If it has 4 different phukin forward speed ratios then it's a damn 4 speed regardless of the raitios being very low or OD. RIGHT?
The actual first Hydramatics did use a clutch pedal to start and stop but the rest of the transmission functions were automatic. Now that's a different animal than what you're talking about. This was before the automatics had the torque converter technology. Those were biggo heavy cast iron automatics. Many also aren't aware there is such a thing as a Cast Iron Powerglide too before they went aluminum.
I didn't watch the video since our internet is slow as hell due to the bad weather, but it's a fairly simple process if it's what I'm used to. You just find the middle or N in the shift spectrum, put your shift levers on the transmission in N, then adjust your rods to match the distance by spinning the threaded ends. Replacing your bushings on the shift rod ends also helps alot on the shifting mechanism.
