put in a homemade lock up switch tonight. did it according to this link http://www.tstproducts.com/Torque Converter Lockup Switch.pdf [/URL] at first i didnt hook up the third post on the toggle to an illumination source. but the light came on by itself when i turned it to the on position. thought this was strange. it didnt change a thing. my tc still came unlocked when i gave it a little juice goin up a hill in overdrive and it still unlocked coastin down a hill with the switch on. i came back and checked all my connections and hooked up the illumination post to a 12v source.
when i'm coasting and the switch is on, it lights up. but its not locked, still coasting. and as soon as i touch the pedal the light turns off and my truck acts the same with the switch on or off. i need help:confused013: any input greatly appreciated. especially someone who has done this before with a 99. i put the switch in because i'm trying to preserve the life of my tranny because my tc has been acting up lately.
oh and some one told me that my tc actin up while in overdrive could be a bad throttle position sensor???
thanks guys

Be careful grabbing random wires and putting them to ground not knowing what they are doing!!!
