Title: Curious about this at the carb linkage
Post by: Polishmeatballpizza on August 14, 2016, 09:32:02 PM
Looks like an electric kickdown switch. Did these old trannies use an electrick kickdown switch? I thought they were all mechanical.

There are two switches used.
The one you have pictured is the kick down switch.
There is also a stator switch. I see the wires for it in your picture. It is mounted on the linkage by the clevis that is in your picture.

Just a regular kickdown switch?

What is the stator for?

That switch serves two purposes. It is a kick down switch and drops the tranny into a lower gear when at wide open throttle and it also controls the switch pitch converter in the trans. At about 40% throttle it will trigger the switch pitch solenoid in the tranny to put the converter into high stall.

Does this mean I have a switch pitch trans?

Dear George and mid-60s Buick tranny experts,

Does this mean I have a switch pitch trans?

Since your car has the original drive train with the ST300 tranmission, yes it does have the switch pitch feature.
