Need TH400 kickdown stuff - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just as the topic says, I need a kickdown switch, bracket, and wiring for a TH400 transmission. Truck has a 350 in it. If anyone has anything shoot me a PM.

Thanks

Cable or rod to carb?
Which carb?

Robert1970C20rstbukt · 06-26-2004, 08:36 PM

If you're talking about the gas pedal linkage, it's the older rod style, not the 71-72 style. The engine's got the original 4bbl Quadrajet w/ manual choke.

You have a couple of options, if you don't find original. Change to the 71-2 assembly (just drill a couple new holes in the firewall) OR install one of the after market kick down switches that attach to the trans.

PICKMUP's right. If you decide to go aftermarket check this out:

Happy hunting for the stock setup. I'm sure you can get your hands on it, it's just how much time you want to spend. If you want to get your truck running in a weekend this is probably the best bet.

I'm using the Lokar setup on my turbo 400. Works slicker than owl crap on a doorknob.

Sounds cool, but I don't have a lot of money to spend, that's why I'm looking for a used one.

This is what he is looking for.
