As most of you guys know mt TCC lockup is an old and to most, including myself, an annoying issue. I just drive the car like it is and if I figure it out I figure it out, if I dont I dont. Took it to a tech I know yestarday for him to do a run scan on it. However, my OBD port would not let him establish a link. While driving it he had me turn overdrive off and it was still doing it. He said turning the OD off is suppose to disable the lockup but it still locks up. Then while sitting in park the darn thing locks up and kills the motor! I didnt notice those two things before last time I talked to you guys. Another thing he brought up was the ground straps and if I had one on the tranny. I dont think the guy who installed this put one on either the tranny or the motor. Said that could be the problem and the reason he couldnt establish a link. Putting those on today. Here's hoping.
