@64Pacific I've never heard of a vehicle with multiple reverse gears? What's it called, I'd love to learn more about it, cus that sounds awesome
My truck is a 1964 Pacific.: https://www.youtube.com/watch?v=xBNZO1k198I
Originally built with a 5 speed main transmission (gears 1-5 + Reverse) off of the engine then a short drive shaft to the auxiliary transmission which is four additional gears (in my case Low Low, Low, Direct and Overdrive) and then the final drive shaft to the rear ends.
Spoiler, this might be a little long winded...
Typically you will start off in 1st in the main and Low Low in the auxiliary, then shift the auxiliary to Low while keeping the main in 1st, continue working up through auxiliary gears until you reach 1st and Overdrive - these are split shifts since you are splitting each gear in the main transmission. When you have run 1st and Overdrive out your next shift is to 2nd in the main trans while you bring the auxiliary back to Low Low, work back up through the four auxiliary gears and then do it all over again for 3rd, 4th and 5th in the main transmission. The same can be done for reverse, stick the main transmission in reverse and auxiliary in Low Low and shift the auxiliary up through its four gears.
That's not too bad, but wait it gets a little more interesting, keep in mind these are non-synchronized transmissions and a diesel should be run in a relatively narrow RPM band between peak torque and maximum horsepower...
Depending upon the gear ratios in the two transmissions you may have to skip certain gears as the ratios aren't progressive meaning you will have to slow down to make the next up shift. In my truck with the setup that it will have after the restoration is complete shifting from 1st and Overdrive to 2nd and Low Low would require too much of an RPM change forcing me to slow down to nearly a crawl to make the shift (these are non progressive gears) but if i shifted to 2nd and Low then the shift would be smooth and I would continue on without missing a beat. The image below illustrates each shift and the resultant road speed (shifts on the bottom, and road speed on the vertical axis); as I look at the chart it is by no means perfect but hopefully helps to illustrate the above - in a perfectly progressive transmission there would be a nice curve approximation to the chart without the sharp drops with some gears. Notice the line between shifts 4 (1st gear and Overdrive) and 5 (2nd gear and Low Low), in order for me to make this fifth shift I would have to slow the truck but if I skipped 2nd and Low Low and went to 2nd and Low (6th shift) I would have a nice progressive increase in my road speed.
