Which 727 Transmission fluid type to use?

I'm topping off my 727 auto transmission fluid level and not sure which trans fluid to use. The transmission has been rebuilt with a shift kit. Fluid level's a little low and want to use some good fluid recommended for the Mopar. Any suggestions? Thanks in advance...
Any brand of Dexron Mercron “multi-vehicle” will be all you need.
It’s honestly not as critical or complicated as one might think. Run at the proper level and using a cooler is what really would matter
