According to the manual, I'm supposed to use C2 transmission oil in the power shift trans on a 1966 545 loader.  I have no idea what oil is in it right now, looks like ATF.  I got 10 gallons (takes 8.5) cost over $19 per gallon!  C3 or I think, 121 is about $9.  Anyone know if I can run the cheaper stuff or should I put the C2 in and try not to think about it?
BTW, I've owned the machine for 6 years and never changed the trans oil.  The dip stick is missing so I guess I need to drain the oil and clean the screens then put 8.5 gal in and make a new dipstick that show's full.

Thanks for the info Dnoym.  I didn't see the the check plugs but will look again.  The fill spout has several bends in it and I wondered how well a dip stick would work.
What oil do you use in it?  Should I use the C2?
Thanks, John

John where did you get that
you should  use the C2?
i have a 1967  545D with a 301
and 2 speed power shift
 i have a 545D operator
manual and in the manual it
say
lubricate these with SAE 10w oil
meeting ATF type c-1
so i think that SAE 10W oil or
ATF type C-1 is what they went
with in 1967 so i don`t think
it need anything special
i don`t know if tractor hydraulic
would work (i can`t see why not) but
the only thing that i did with mine
was to take out about 5 gal of
oil because they could not find
the dip stick
to check oil set park brake
take the top plug out with dranpan
if no oil add oil replace plug
and start engine and run at 1000 to
1500 rpm for 1 min. to charge system
then take out the bottom plug  and
add oil as required stop engine
this is what mine look like
