The Biondo shift solenoid in my car is old enough to be in the Smithsonian lol. Was bought in the 90s. If it ever lets the smoke out I will try to get it warrantied.

For everyone's information, I have installed three "Shiftnoid" kits in three different racers, and all have performed correctly with no issues. It only requires 0.02 seconds to signal and complete the shift. The wiring is per the instructions with an included relay.

The CO2 question/issue is for the starting line controller.
