I have a 1994 camaro z28. Engine, and trans are from a 95 lt1. Pcm and engine harness are original to the 1994 car. What is the easiest way to bypass the tcc lockup/pwm function for the 95+ 4l60e? Can you bypass it manually using the solenoids? Bypass in tuning? Or run an extra wire and brake switch to enable lockup?

easiest way, probably to stake the pwm valve open in the valve body.
You can also run the additional wire, then reprogram the pcm as a 95...
See my link in this thread.
