Engine/Transmission (1994 - 1998) WOT switch and Mystery Switch

[biggy238]

With a little wiring, I think it could be possible to wire a Wide Open Throttle switch (such as used in a nitrous app. ) and place it so that when the throttle snaps shut, it will disengage the switch that I would use to run my mystery switch.



No babysitting rpms or monitoring stops with one hand on the switch. Take your foot off the go pedal and the lockup kicks off. This would be for street use only, not for exhaust brakes. (It could be reworked for that though)



Sound like a good idea to anyone else?

I don't think it's throttle position that you want to worry about. It's how much torque you are making. One way to switch according to power is to rig a hobbs switch to measure boost.



If you are not racing or doing something else in competition, I question the need for the manual lockup switch except for use with an exhaust brake. It's very hard on a stock trans to shift with the TCC locked. I control my lockup with an old fashioned dimmer switch ('63 Chevy part). In one position it connects the ground to the switch. In the other it connects the ground to an LED on my switch panel. No fumbleing around with a switch on the dash except to choose between the manually controlled lockup or the stock PCM control.

I like that Joe.



And yes, It would be for racing, and actually some of the hill climbs I have around home I think it would be very helpful with the tires I have. The problem I take the greatest issue with is the truck kicking out of lockup at high throttle on some of these hillls. If I try to accellorate from 55mph (1500rpm) with enough throttle, it unlocks the tc and i'm dead in the water.

I just want the automated unlock before the truck lugs on decelloration.

If you rig the ground for the manual lockup switch to a dimmer switch then you have complete control over lockup. Your left foot has nothing else to do anyway. I used the '63 Chevy (I used to own one of those) dimmer switch because I knew that the contacts were above the floor board instead of on the underside like a lot of those kind of dimmer switches were.

My first love- my '85 bronco had a kick dimmer. It had a clutch though.



We'll see... Got my OF valve today... Waiting for the heat to die down.
