3 way lockup switch

[skyhigh4by]

I’m thinking I’d like a lockup switch but I also want the option of having fully factory operation for when my wife or some other unsuspecting person drives my truck. I’m thinking factory/unlocked/locked.

 

Is it possible? How would one go about wiring that up? 

 

Reason I want a switch is my triple disk converter seems to lockup to early for my engine. (All stock engine/tuning with exception to trans goodies from dynamic and the triple disk TC) It severely barks the turbo sometimes if I’m into the throttle enough or if I’m really light on the pedal it will actually lock and then immediately unlock almost as if it quickly realizes it’s too soon. This happens around 43-45mph. There is zero ac noise and I’ve replaced both speed sensors with no resolution.

See if this will work for you.

It doesn’t seem like this has an option to function like it came from the factory? I don’t want to have try to teach every person that drives the truck how to operate the lockup.

The typical method of manual turning on and off the lock up is more problematic than what @IBMobile posted up.You can lock it up but the brake pedal will cancel it. I know @IBMobile can explain it better.

I understand but what I want to avoid is having to train anyone that drives my truck how and when to lock the torque converter.

@skyhigh4by Correct me if I'm wrong, but the way @IBMobile has the lock up switch wired the truck will lock and unlock the converter normally --like the switch doesn't exist-- if you don't activate it. His switch just allows you to lock the converter when you choose to. If you don't touch the switch--normal transmission function. You push momentary switch---converter will lock and stepping on brake will unlock. Push momentary switch AND activate toggle or foot switch---converter locks and brake DOES NOT unlock converter. Anyone can drive the truck as long as they dont touch the switches. It parallels the factory circuit and should have no effect on factory functions unless you activate it. It should do exactly what you want.

What @Gregturley said is how it works.  Don't push any button or switch and it's the factory setting.

@IBMobile Just today i started wiring up your lock up for my truck. I've got everything wired on the bench with extra wire because i haven't decided where I'm putting the switches yet. Now i just need to find time to get it in the truck. Thank you for the work to design this and the excellent write up to go with it. It still amazes me the amount knowledge and help available on this site from yourself, @Mopar1973Man, @Dynamic, @Me78569 and everyone else. Thanks to you all.
