Overdrive kick-down switch bracket for straight six - The 1947 - Present Chevrolet & GMC Truck Message Board Network

sfcharr · 04-25-2019, 07:38 PM

I am trying to get my overdrive transmission working as designed but I'm missing the kick-down switch and bracket. Does anyone have a picture of the bracket? I am good a fabricating but would like an idea as to where to start. My searches for this bracket has come up empty, 250 straight six.

thanks in advance

Anyone have a picture or a diagram?

What overdrive are you talking about?

It's a Muncie, 3 speed. With a a non-syncro 1 gear. I am trying to get it operating as it was designed, at least as close as I can get it. I just need some ideas on the kick-down bracket

I am doing the same project later this summer. I have a 72 with a 292 so it should be close to the same. How far along are you?
I have a kickdown switch and bracket but the bracket is for a 63 Impala I believe was a 283. judging from the oily film on it, it was mounted on the carb. I was thinking of mounting it on the bracket the gas pedal is mounted on so it comes in contact with the cable. I'll send you a picture of the switch and bracket later.

I have everything to complete. Need to fab the bracket, then mount the relay, hook the harness up, should be ready for testing.

Sorry it took so long to do this. Hope this helps.
What gear oil did you use in your transmission?
