i need to change oil for the torque converter, transmission, steering clutches, and brakes all one unit on the 7G. the factory manual says use transmission fluid type c-1,or mil spec L2104 which is out dated now L46152 (looks like motor oil spec to me). i have been using hydraulic oil light weight seems to work ok but have not put many hours on it. im totally confused as to what to use. anybody got any info or ideas.
You can use SAE 10 oil (no hydrolic oil)
use tractor transmission oil .oil supplier can look up newer spce,s for you
