Re: Ultramatic

I've been going over my 53 Cavalier's Ultramatic and getting all the settings back to factory specs. Most everything was pretty close, with the exception of the throttle cross shaft and throttle valve lever. (I didn't check hydraulic pressures.)
I'm trying to understand better the shift pattern as I think it is different that what I had thought.
I had thought the direct drive was the last to engage, but as I review the service manual more I don't think that's correct. I think it goes Low, then the Direct Drive kicks in around 15 mph, and then High kicks in around 30 mph depending on how much throttle is being applied. Is this correct? I'm not a transmission expert, and certainly not a 71 year old transmission, but trying to understand better how it functions.
