As for a scan tool to suit your needs, it sounds like everything you have would be pre-OBD-II which makes things more difficult. Of course something older than 1981 is unlikely to have any built-in diagnostics. But for the vehicles you have, unless they are all domestics or all a single brand, it could get expensive to try to equip a scan tool to work with them all. Many of the early diagnostic systems have a way of pulling codes (no datastream though) using a jumper wire and Check Engine light, multimeter, or screwdriver and watching an LED on the ECM.

the buick is a v6. i assumed it was the transmission causing this trouble.
