Have you owned / driven a GV w/ a std trans & shifted it progressively? Sure be interested to know how they perform!
Yes, we had a shop truck with a NV4500 and a GV. The NV has some fairly large splits so the GV worked very well with that trans. Drove that truck fully loaded towing an enclosed trailer with a race car with a full set of spare parts and tools from the shop in San Diego out to Colorado Springs. We had the manual switch for the GV mounted on the gear shift so it was easy to shift both units at the same time.

If you are concerned about the split ratios, it is easy enough to figure out what the splits would be if you know the ratios in your transmission.
