    I have heard that eventhough the fisher pump says right on it to use ATF that it slows the pump down. It is alright to use tractor transmission and hydraulic fluid? I have heard of other ppl using this and it speeds up the pump and performs alot better but I dont want to ruin any seals in the pump or the rest of the system. I have John Deere transmission and hydraulic oil in teh garage, use it or no?

    I have been using ATF from the day i got it and i have used it in -5 degree weather and not had 1 prob with it and i have the old fisher valve type(on the outside)..Its also cheaper to keep an extra quart behind the seat..NO WORRIES :drinkup:

    check out your local oil dealer they may carry an oil equivalent to aircraft hydraulic oil stays thin in any tempature it is expensive so make sure you don't have any leaks but well worth it in -30 weather or an ESSO brand oil called J13 ---- hydraulic oil is still a little too thick
