Re: turbo 400 kickdown switch

The mount has different holes in it for the switch. Finer adjustment in the past I have put a piece of hose around the tip that sticks out

I will look at the one I have in the morning and take a couple of pictures of it to see if there is anything different on it.

i am not seeing any adjustment in the mount. switch can only fit in one position. I have seen different posts that say you need to reset switch and then depress accelerator to self position, but i have had no luck trying the suggested reset methods.

I'm thinking like you said putting something over tab that sticks out

Here is the one I have. I see no adjustment in the bracket or switch. There are three holes in the bracket, two of them are for locator tabs on the switch and one is for the screw.

The instructions for adjustment you are reading are for the TH350 kickdown CABLE. I don't know if any of the 400's use that system or not. That adjustment will not work for the electric switch.

Re: turbo 400 kickdown switch

The switch is self-adjusting.

There is a locking tab on the switch which can be moved by finger pressure-- it's on the rectangular beige plastic part right against the steel. Just a silly little spring tab. Start with the pedal in the idle position. The switch won't be contacting the metal of the gas pedal assembly. Push in the tab on the switch, and "force" the movable part toward the pedal--you'll hear the ratchet/clicking noise. Then allow the switch to come back to it's normal position, so that spring tab pops out again. THEN move the throttle to wide ope, this sets the adjustment. There should be no need for rubber tubing on the gas pedal if the switch is adjusted properly.


I was designed so it could be installed at the factory and the first time the vehicle was floored it was set/adjusted.
Cheers

The only thing I can see are these tabs. Is that what you are referring to?

Re: turbo 400 kickdown switch

I have same switch as lockdoc. I'm having no luck pushing the tabs lockdoc is pointing and pushing moveable part of switch. I must be missing something or maybe switch bad?
