Title: Relays
Post by: treeplanter on September 30, 2021, 01:38:11 PM
Does anyone know what these Potter&Brumfield relays control on a 1971 Fishbowl?

Are they tied to any of that aftermarket valving on the top of the transmission?

You may have a custom tranmsission control?

Happy coaching!

It looks like to me a force downshift set up for the trans. The VS2's were known to downshift late so you can force them to down shift with the movement of a switch.

Thank you I was thinking that as well.
