Need some HELP decoding a 700r4 Transmission

I recently purchased a 700r4 to switch out for my Powerglide but I'd like to decode it first and possibly rebuild. It has the MD8 so I know it's a 700r4, the serial number is 7YXM163H. I know the
YX=model code=????????
163= 163rd day of 1987
H= second shift

Does anyone know what the YX model code stands for?

Does anyone know what the CH model code stands for, my uncle also has a 700r4 at the shop that I could have but need rebuild?

Trying to figure out which is my best bet or best route to take.
