Simplicty hydo PEERLESS transmission fluid

[SouthValleyDan]

Greetings, I am trying to locate fluid for my simplicity 4212H Briggs & Stratton mower. It has a PEERLESS hydo transmission numbered 7058 6444
Can anyone point me to the fluid I should use? I am changing it as the fluid is black and based on the oil I changed this week in the engine it has not been serviced in a while. Thank you much!

The gear box uses gear oil and the Hydrostatic part uses Tecumseh PN 730228A which is Synthetic 15W50 motor oil. Walmart sells Mobile One SYN 15w50 motor oil.
