Drag Run with a ZF6 Auto. Check you Dyno sheet and find out what RPM your car makes Maximum power before it starts to drop away ( this is your shift point, Mine is 5800 RPM.)

Foot off the Brake and exalerate flat to the boards. I dont have a shift light so I Watch the tacho and change to second just over 5800RPM.
