Ever wondered how a Pro Stock Car’s 5 speed trans works? Well here’s what you need to know! These guys only have seconds to make moves between the time they let out the clutch and when they pass the finish lines, that means these transmissions have to be FAST! What has to be even faster is the crew who pulls the trans out of the car, rebuilds it, and puts it back together. These NHRA guys are nuts, watch and learn!
