Re: what vehicles came with 200r4 from junk yard
there is a 3 letter code stamped on a small plate that is riveted to the right side of the transmission body near the tailshaft. This 3 letter code is the valve body calibration. My transmission guy, who hates 200's tells me to find ones with the firmest code. If you look online you will find the codes, and what the trans might have come out of. BRF is like hens teeth. Buick Grand Nationals only, but the best for firm shifts. If I remember I will look for this site and share
