Transmission fluid & model year id

Older Clark, C500 y50.
Sat for years and im bring back to life.
Shortly after i got it running / moving it around it blew one of the crunchy lines
Pulled the 3 hyd lines going in and out of radiator to trans and filter housing to have made up.
Now need to figure out what fluid was in it... was dirty / black but feels like atf. Unsure.
Trans has the 2 lever on left side dash H/L F/R

Serial number
Y355-463-2530 471


If anyone could point me to proper fluid for this and possibly the model year of this thing.
Thanks

Thank you John , But I found the year out yesterday afternoon..

If you have the part numbers for manuals for this unit or a place to go for them , that would be great.
Thanks again

Most Clarks used Dextron 2 in trans
Up to the newer units
Clark dealers sell a trans fluid that is compatible to all of their units old to new
