Just a novice observation here, but...

Wouldn't the ground speed at which the transmission shifts depend on how much load the engine is under, the rear end gearing, and the tire size? Or maybe a Power Glide wasn't that sophisticated and you just set it to shift at a certain input RPM.

Just thinking out loud...er....typing...or...whatever. Thyping? Tynking? IDK...

If I am getting you correct.

The Down shift cable is for the "passing gear" on a power glide ... well there is not a lot of options for passing gear.

My 67 Bel Air 250 1 bbl Power Glide Would shift around 25 MPH normal & 60 ~65 MPH with the Go pedal matted.

My 66 Skylark 340 2 bbl Pwr Glide would shift about the same it would idle @ 20 MPH


Did this help?

it would go by engine RPM not MPH, there are to many variables to pick out a standard MPH
there are also a lot of variables for RPM such as motor and tourqe converter
some more info on the car would be hepfull
and i dont believe joe g was trying to be a smart***
things just dont always come across a keyboard like they are intended

Maybe I should have worded my last comment differently or used some smileys or somethin'.

I wasn't being a smart***, I was just saying that there are many factors that determine when most automatic transmissions shift. But Powerglides, being an early form of auto tranny, might work in a simpler manner for all I know (hence the calling myself a novice).

You question is a good one. I hope to learn more about how Powerglides work because of this thread.

Didn't mean to piss you off, Man.
Sorry.
