I am working on a Gilson 53040. Can't find much information online about it.
I need new oil in the transmission, can anyone tell me what spec.oil to use?
There is a plate (attatched photo) on the trans. that seem to read "PEERLESS 9304 208...".

The fill plug should be at the back of the transmission near the hitch. I looked through my manuals and found that it requires 90sae gear oil, 80w-90 sould be fine though.
I did a little research and found that it does take 2 quarts, but it seems odd that you had to tip the mower to fill it with oil. Maybe i was wrong and your supposed to use the shifter cover to fill the axle.
