[69fastback]

Best way to go with a auto is to get a manule valve body. I put one in my 69 c-6 and it made all the difference in the world. I have a performance automatic manule vavle body to put into my 91 aod car. You shift the car at whatever rpm you want to for 1-2-3 then you flip a switch to go into overdirve. I can't wait to get it into the car i know it will make a huge difference.
