I have searched but I cannot seem to find a definite answer. I just installed a 3600 stall converter and a fully rebuilt transmission into my 2000 Trans Am. The trans shifts great, has a Transgo HD2 kit, my builder eliminated the PWM in the valve body. The issue I am having is the torque converter lockup. It will shift fine on the 1-2, 2,3, and the 3-4 but when the converter locks up it locks then unlocks then locks etc etc etc. How do I fix this in my tuning?

Thanks!
