Hello, i am turboing my 1967 Mustang l6 and as of now it is automatic c4. i would like to get a manual but that is out of the budget. i know the auto trans use vacuum to shift but im going turbo. how do i solve this. i know many people use a check valve but im planning on running about 15 psi and i dont know if that will handle it. also can i run a check valve on the brake booster aswell or do i do something different whith that.
Thank you
