I am looking around to get the best torque converter lock up controller or switch. Which ones are better than the others. If ya'll could help me out i would really appreciate it.

 

The lockup is controlled by applying ground to the wire coming from the tranny. Just get a wiring dia. and put a switch on this wire. that will give u full control. Sorry about the lack of detail i dont own a auto so i dont know wat wire it actually is but my friend has a 97 auto and thats wat he did ill try to get some more info on this if u still need it
