	The transmission, had 5 forward and one reverse gears. The loader transmission had 4th forward gear turned into a reverse, so you had 4 forward and 2 reverse gears (mine is a loader though with 5 forward and 1 reverse, I don't know why though). This is according to my book that I have for my crawler, don't know how correct the loader 2 speed reverse is since mine doesn't agree with what the book claims, but one guy I know had one too, and he said it had the 2 reverse gears, and another transmission I've seen out of loader also had 2 reverses.

	the original configuration was with the single speed reverse , later updates went to the 2 speed. It may have been updated later , the 48 HD5B I had someone had changed the transmission to 2 speed reverse. All the later HD5 machines I had used 2 speed except for one 5G I bought for parts , early Srl# and trany was single speed reverse. Unsure at that point if someone had swappd these with later or rebuilt with the extra gear . Case is the same for both .
