Shifting into overdrive

[snamelc]

I know there was a thread a few weeks ago concerning how to shift into overdrive but I haven't been able to find it. There were many opinions on it but I don't remember this one: Shift into OD as if you were simply shifting from 3rd to 4th... push in the clutch, let up on the gas, flick the OD lever up (Series II), release the clutch, give it the gas. I tried it before I realized I could possibly wreck something but it worked so smoothly, I wondered why I hadn't been doing that all along. Now I'm wondering if I was just lucky and could I cause some damage to the OD or transmission. Would anyone with first hand knowledge please weigh in? Shifting under power, I get a thunk!! that seems harsh enough to be hard on the OD.

This article has lots of info about OD, if you look through it, you'll find some shifting info.
In my personal experience I shift into and out of OD just like another gear, seems to gentler on the unit.
I'm sure there will be more opinions.

Sometimes I use the clutch, but often just lift off the accelerator to give a smooth engagment/disengagement.

When downing shifting in OD, simply keep the accelerator pedal where it is and simultaneosly clutch in/out and shift. The split second delay between the clutch and the OD downshift, perfectly matches the rpm increase and results in a dead-smooth downshift, assuming the mph remains constant during the shift.

The Series II owners manual says to engage and disengage the O.D.with the throttle depressed. Don't say how far.

Doest really matter so long as the engine has enough throttle to allow the RPM to increase as the gear drops.

The point is to NOT use the sprags in the one way clutch, but rather let the cone clutch take up the force.
