looking for some help with torque converter lockup issue on my 2004r. I have lock up running of of a switch. Lockup was working. became intermittent. now does not work at all. i started with the most obvious easy stuff. check all my wiring to make sure plugs and connection had good clean surfaces. Replaced purple power wire from switch to trans plug as it looked pretty beat up and crushed in a few places from when i did my trans crossmember. with car off i checked continuity from switch to plug then the passenger side trans pressure switch above pan had continuity from power in to ground. but i can not hear the tcc solinoid inside trans clicking as i plug and unplug the 4 pin connector. have not dropped pan yet. fluid looks nice does not smell burnt at all. all other functions of trans are also fine. when the lock up did work it also only dropped between 100-150 rpm. thought is should drop more then that . Any help would be appreciated. not automatic trans guru by any means.
