You got it right...............

440-T-4, 700-R-4, 200-4-R, 200C some them so bad that the factory said when you get it figured out call us and we will put out TSB's....

They built them and early in the production runs we had to figure out how to fix all of the drivability problems......

As time went on the factory got a handle on them and had updates for the problems...

I worked at several dealerships Chevy, Pontiac, Olds, GMC & Cadillac but no Buick dealerships and we raced one of those also............
