That IS how it works. A 3 speed OD is essentially a 6 speed transmission. With the OD off, you get the everyday, standard 1 thru 3. With it on, you get 3 additional gears that are stacked on the first three. 1 and 4, 2 and 5, 3 and 6. Granted 1 and 4 are pretty much useless since as Bill states, the OD is locked out at about 30.
What I want to know is, I am hearing people talking about letting off the gas to get things to engage, I personally take it out of gear, and put it right back in again to get it to shift at the proper speed, what is the correct way to shift it? When I get to this stage in my rebuild, it would be nice to know the CORRECT way. Not the way the manual states unless its the same as what practical application from people here use.
My old friend, the late great John Erb told me to NEVER engage the OD below 30 mph, rather turn it on AFTER 30. If I didn't do what I was told, plan on rebuilding and replacing a lot of stuff. He told me to make this mistake ONCE and pay dearly for it. Had to do with putting it in reverse with it on being a bad thing. So, he was the local guru, what is the consensus here?
