Default Kickdown blocker DIY - 10-24-2012, 05:20 PM

Hey guys,

We've been toying around with making a nice CNC machined kick down blocker for automatic transmissions. Also considered doing an electronic one. But other projects have become a higher priority and this simple DIY works pretty well.

Kickdown blocking is useful for the following:

1) When drag racing it allows you to perform a 2nd gear launch without accidentally downshifting in to 1st gear. Critical for good track times with boosted automatics.
2) When doing dyno testing this will prevent you or your unaware dyno operator from pressing the kick down during a run ruining the run.
3) Some of us prefer to manually downshift when racing and this eliminates the chance of the car downshifting when we don't want it to.

The photo shown is a 135 gas pedal. The 335 pedal is a little different but the same basic procedure should work.

It's not every day you stumble across a <$10 DIY that works exactly the way intended, will never fail, and tremendously stealth!

I'll take a few photos on the 335 gas pedal implementation tomorrow. The 535 uses the same pedal as the 335 as far as I know.

Very simple thanks Terry. Hope that the electronic fix also makes it on your list at some stage too!

Is there any situation that you would actually want the kickdown to work?

Let's see if we have those gripper bars here in Canada.

Now if we could have something to prevent the god damn car to shift automatically!
