Is your pump on the transmission PTO port, or run via a drive shaft from the PTO port on the transmission?
If you have an auxiliary transmission, it was added later. Not uncommon.
Is your main transmission still a 4 speed?
What wheels do you have? Widowmakers were installed on many of these.

A Spicer 5831B has three gear ratios:
2.35:1 under drive
1:1 direct drive
0.85 overdrive
If you have a 4 or 5 speed transmission, I wouldn't be concerned about driving it with those transmissions.
Lots of videos on Youtube of people driving those two stick trucks. My dad drove several over the years. 5/2 and 5/3 transmissions. I remember the first gas engine truck he drove with an 8 speed Road Ranger before the company went diesel with 15 speed deep reduction transmissions.
You had to have the rpms on the money to shift the Road Ranger with a gas engine. Much easier to do with a diesel.
In the 60's and back, these setups were common in gas engine heavy trucks, and many OTR trucks. Macks were famous for their 5&2 duplex transmissions.
