Just added a tc lockup switch to my truck. i did it myself. the problem is i'll turn it on, and it will only choose when it works, like every once in a while. you can definately tell when it does work. all connections are good, and the switch is good, what could be the problem?

good ground? which wire did you use? your t/c might be going out or there is a loose connection on the transmission. Did you jumper your transmission relay in the under hood fuse box?

did you use a 33ohm resistor and jump the Relay?
