Thanks Barry! You can PM me or email me bobby.fazio@gmail.com.

Anyone hook up this setup using a Turbo Action Cheetah with a reverse pattern 3 speed trans ?

I'd like to try it and making a switch to only work in low gear looks like a challenge.....

I haven't done it with a reverse pattern but I think it could be done fairly easily by mounting a momentary, lever micro switch on a bracket attached at the trans pan rail or in tandem with the shift cable bracket. Switches like these are available in short or long arm for less than $20. Should be able to activate when the shift lever arm is in low gear only.

The problem with that on a reverse pattern is the shifter or lever is moving toward the switch as you upshift. The switch would also be in the way going back to N-R-P

I've made switches like that on other cars but the shift pattern was forward.

I'm sure it can be done but it takes some thought and fabrication

The built in neutral start switch posted above is a good solution

If you're just bracket racing and not class racing I did it an easy way. I put a trans brake button on the steering wheel. If I put my thumb on the button it would energize the circuit for the brake pressure switch. After launch I just moved my thumb. On 3 speed GM transmission you can use a pressure switch on the transmission pressure port.

With the switches I posted a picture of, I was thinking of mounting it between the pan & shifter lever, letting the inside face of the arm touch the roller on the switch lever. In this arrangement, it would only contact in low gear & wouldn't affect the lever's range of motion either direction.

I just have a push button on the back of my Cheetah shifter & the shifter contacts it in low gear (forward pattern), activating the brake pressure switch.

Slightly off topic here, but is it legal to use a momentary switch that's not mounted directly to the brake pedal that you hit with your foot? Like a WOT switch on the back side of the pedal that makes contact when the pedal is depressed a certain amount? I could go through the rule book and check myself but I'm lazy and I don't want to. TIA

Easy to do. I use a neutral start switch I got from turbo action.

Thanks, that is a great solution. I didn't know if it would work

I'm an old pure foot breaker but always open to trying something different.

When I owned this car in 2006 I did install a 2 step button switch and low rpm adjustable chip but never used it.

It was not comfortable to me leaning hard on the brake pedal and using that hand operated button.

Using the brake pedal with a pressure switch sounds more appealing

I have taken the shifter apart at least 4 times to do various things.....one more time can't hurt....
