Re: R-6 overdrive transmission questions

I have a rebuilt R6 in my '39 Packard Six with overdrive. Much time went into hunting for a good main shaft, clutch gear and cluster gear and I hesitate to drive it one foot until I understand thouroughly when I can and cannot engage the OD.

And, I will admit that my knowledge of transmissions is next to nothing so some of the lingo used in previous posts has me more confused. Any help will be greatly appreciated.

My questions are these: 1. Can the OD lever be pushed in (engaged) while the car is moving forward? 2. Can the car be taken out of OD while moving forward or must it first be brought to a stop? 3. Can the car be put in reverse while the OD lever is in (engaged) or must it first be taken out of OD? 4. Is there any time downshifting can be used to slow the car either in or out of overdrive? 5. And last, when I park a staight drive car, I always leave the gear in reverse. Does it matter if the OD lever is in or out?

These may seem like dumb questions but simple answers will be appreciated. Thanks much.
