Manual shift problems
After installing the paddles in my Trans Am I lost an engine. So the car has been down for a bit. I'm up and running now and last weekend I took the car out for a spin. I flipped the switch for manual mode and ran it through first, tapped into second, wound it out and tapped again, no shift. I figured it was just me so I flipped it to auto and waited for the next stop light and tried again. Same results. Tonight I put the laptop on it in the garage. To refresh you, the this the TCI "red box" controller and software. I opened the dashboard and could see when I flipped the switch to go to manual mode. I tapped the upshift and went 1-2 but no 2-3. The downshift of 2-1 works as well. FYI, this all worked flawlessly after the install, before the motor crapped out.
Any thoughts on what might be preventing it going beyond the 1-2 shift in manual mode?
