56 Powerglide kickdown linkage

[Edward M.]

I cannot figure out how the kickdown linkage works on a 56 Corvette. I see the diagram in the AIM, but I cannot figure out how the kickdown lever on the side of the transmission (Lever D on RPO 313, sheet 5.00) connects.

I am specifically confused about how the lever attaches to the clamp (E on the same AIM sheet). I can see that the lever bolts to the clamp, but what keeps the lever from rotating as it is used. Surely it is not just friction that keeps it in place.

Any help greatly appreciated.

{Surely it is not just friction that keeps it in place}. yep! That's it!

Friction fit, hmmmm, is that the same on all Powerglides?

So we have the PG on the new(old) 63 coupe, and has no kickdown lever from the upgraded Carter Competition AFB. I have one on order. I thought the kickdown was solenoid actuated, but see it's not. My son and I did some research in the service manuals the other day and couldn't find reference to this......At what speed will the kickdown be over-ridden? i.e. if at say, 70 mph, will it try to downshift to 1st? Seems like it could over-rev the engine.

Re: 56 Powerglide kickdown linkage

The PG kick down rod is adjusted to the Carb linkage when the Carb linkage is held wide open . It won't down shift after 50 mph. You! just move the lever to low when you need to pass doing under 50mph // But then it will at any speed. If you dont have the kick down connected it will shift from drive to low quick , when it should around 35-40 mph.
