Problems like this is usually the torque converter clutch solenoid, and not the converter. Replacing the solenoid should help

Thank you for the response, the question I would have is since the car has a custom lockup convertor kit that contains the solenoid, pressure switch in the valve body area, the vacum switch on the firewall which gets its power from the brake switch.
The kit was in the car when I got it, and it is from Speedway Motors which gets them from Painless wiring.
I called the tech line at Painless and he used his troubleshooting guide and said to disconnect the power from the brake switch since this is the only power soucre to the vacumm switch to the trans solenoid. I did this but it is still locked up.
My assumption is the Solenoid or switch in the trans is bad, but i am leaning towards the solenoid. Based on your feedback since this is a custom application would you recommend buying the parts for the kit and replacing it?
I am trying the cheapest route first and from what I have read on line the torque convertor would not be the problem but it would be the TCC switch, Mine does not have it so I would assume the solenoid is the same thing that sends the command to lock up the convertor.
Even with power removed if the solenoid is bad most my car buddys that have discussed it with a few transmission guys are saying the same thing its the solenoid.
I ma not a 700R4 expert so any advice that you can provide would be helpful.
The transmission guy is telling me over the phone it sounds like its in the valve body but before I go down that path I am willing to try the solenoid route first.
Forgive the delay in my reply as I had problems with my ISP.
Anytime I've seen a problem like yours it always was the solenoid and I would go that route in your case, and getting the part from the kit is recommended
