regular atf
and like 20-30? engine oil
 
idk i took the cap off by the kick start and unscrewed the bolt on the bottom of the motor so what oil is that and what do i need to put back in it
 
yup that'd be the trans oil. some guys will use regular ATF in theirs. just get the ATF type F for older fords and put it in
