Default Is it possible to disable an F-Type's transmission kickdown...

...simply by disconnecting the switch? I've done this in other cars before but they were much older and much simpler. I've found the switch but I'm not sure if disconnecting it might cause some chaos with the car (or if it even can be disconnected), thought I would ask around first.... searching finds loads of threads on fixing kickdown that doesn't work, but nothing on disabling it when it's working fine! Workshop manual doesn't mention it either, just shows how to remove the whole pedal assembly.

I believe I can 3D print a cover to block it, but it would be quite a bit easier if I can just unplug it haha

Thank you

Easiest way to disable kickdown is avoiding flooring the throttle.

Sounds about as fun as seeing a call girl for a cuddle

Yep, I had a box of thin pads (I think for furniture feet) that have adhesive on one side and padding on the other. Guessing maybe 1/8" thick, maybe a little more - cut a small square and placed it in a way so it stops the pedal from triggering the switch - 100% throttle is still reached but no more kickdown. Works perfectly.

Thanks mate, I was looking at disconnecting the switch rather than blocking the pedal travel but the workshop manual only shows a single connector to the pedal assembly I could figure out which wire is which and just pull the right one from the connector, but the main reason I wanted to disconnect the switch was so that I can just easily re-connect it to put it back to stock any time I like.

I think I can 3d print a cap that will stop the pedal right as it first contacts the switch:




I'm avoiding foam or padding as I like to have a hard stop at the end of pedal travel, but knowing that your pads worked gives me lots of confidence Thanks again!

Superb idea.

If you make these and they work....would love one too.

Please let us all know....

I have plenty of extras, I could cut them up and mail them to everyone, I think I could supply a solution to most F-Type owners on this forum lol. Works pretty well so far - these are furniture pads so they don't compress easily, but will absorb any shock. Let us know how the 3d printing solution goes.

This is where I'm up to:



It's a simple idea - the cap will rest on the outer case of the switch, and the top of the round part of the switch that contacts the pedal will sit in the hole. If the top surface of this block and the top surface of the button are flush, I should get exactly 100% pedal travel with a hard stop right where the pedal kisses the button. The pedal is very much in the way so I found it too hard to get in there and measure anything... instead I'm just printing quick prototypes until I find the right size then I'll go from there. I'm up to prototype #3 to get the square dimensions correct and I think this one will be very close The top thickness hasn't been measured yet either but once I get the square right, that should be easy.

This is actually for my XES but the XE forum here is dead, so I carefully worded my question so I could ask in a busier forum then extrapolate the answers to my car 🤣 I'll start a thread in there once I have a solution!

By that time I've missed whatever I was trying to do which isn't a big deal most of the time (just annoying), but in an emergency situation or on the track I need the car to do what I expect it to do. I'm 41 years old and this is my first auto - having driven/raced nothing but manuals since I was seven, I'm finding it difficult to re-train myself to avoid the kickdown especially in an emergency.

I've had one near miss where I had to accelerate out of an emergency but the car hesitated, and one near miss is enough for me so the kickdown has to go.

Or try this, RWD R modified to 650+ hp, quick lane change I do NOT want it to kick down if I put my foot down a little bit too far

Also helpful if you are trying to do data logging runs and want a full-throttle pull in third gear from 3000-6500 rpm.
