TCC locked and limp mode starting

I've got an '87 GTA 350TPI and am using the ARAP bin and 165 ecm. The car has an auto trans with a B/M 2400 stall converter and was rebuilt about 5000 miles ago. yesterday after trying to get my tunerpro program to log data, and having the key on and off multiple times , I disconnected everything from the datalogging port and started the car and it started in limp mode. I tried starting with solenoid disconnected on the trans and the same result.

I've reburned the chip with a stock ARAP bin and even tried another chip and computer. No dice. Could there be something else keeping the TCC locked like the solenoid itself. With tunerpro connected and the key in the ON position, it shows in the bit data TRUE for 3rd gear and the car is not even on. It also shows TCC locked with the key on and car not running...

Any idears on this one.???

Thanks,
Chris
