Hey guys I'm getting the car ready for a cross country haul and I have a question. My TCC solenoid went out about 2 years ago. I've been driving the car with the converter locked this whole time. The car drives fine and I already have a tranny cooler to help with excessive heat. I've heard that driving long distances can kill a tranny if the TCC isn't functioning properly. How do I go about fixing this? Heres just a breakdown on what happened to it.



When I gutted my wiring harness I made the mistake of not hooking up a ground wire for the TCC and now when it is plugged in the car will shift WAY to early and the converter unlocks at like 30 mph. The car bogs horribly, but if left unplugged the car drives around just fine, has for the last 2 years of racing and daily driven abuse. So I need some help to get this car cross country ready. Any help would be great.

Well, your statements about what you've done and what happens are a bit incomplete and confusing..
What's remaining of the original wiring and controls for instance?

Anyway, driving with it unplugged should leave the TCC unlocked. This'll give you a lower highway mpg than optimal, with the difference being wasted as heat in the TC. With an extra cooler this should not present any problems. Imho the "rumors" of it overheating are grossly exaggerated.
There should be several threads & information around here describing how it works & how to hook up a switch for it.

I did not have my torque converter locking up for the first 2000 miles when I owned it. My transmission is still doing fine. There are several kits available at jegs or summit that have will automatically turn on and off. Which is good because under load or braking heavy you do not want your torque converter locked. These kits will automatically disengage. They are approximately 150$ probably the best choice. What I have done and is a lot cheaper but does not work perfectly is hooking up a manual switch to the trans. You will probably forget to turn it off/on once in a while, causing added stress to the trans. I see that you do not have your factory harness. Neither did I so the FAQ article was less than helpful. There are three wires that enter/leave the driver side of the trans. I don't remember exactly how to hook it up, but I contacted PATC http://www.transmissioncenter.net/ and they were able to help me out. I know that you need to supply power to one of the wires and and ground one of them to get the torque converter to lock. Sorry I could not be more help but there is no way for me to get under my car to take a look.
