So I finally got my car running good and have some confidence in it. On my way to work today I finally put the go pedal to the floor for the first time with the new transmission. It didn't take long to bury the needle. My question is even tho I was at WOT the trans shifted gears at 4k rpms. The edlebrock intake thats on the motoe is rated up to 6500 rpms. If I understand correctly from what I read the valve body in the transmission is what controls the shift points and I can't do anything about it. Is this correct? If I cant do anything about it, is it ok for me to manually shift the gears with this trans? The reason Im asking is I have a friend that drag races amd I'd like to try it sometime. Any insight is greatly appreciated. Thanks
