1952-59 Ford Question about trans fluid

I'm installing a 302 and 5 speed from an '85 Mustang in my '56 Fairlane. I think I read somewhere that the 5 speed uses ATF fluid instead of trans oil. Does anyone have any info on this?
Thanks, Ken

 

You are correct on the ATF. tnrotter

 

You are correct in what you have read . The T-5 Ford Trans uses modern ATF trans fluid . I had one and used a high grade synthetic trans fluid from AMS OIL .
