1650 Transmission oil IH or Type F
 

I am sure that this issue has been discussed to no end in the past but I can't find the thread. I would be willing to bet that the oil in my machine is the original or has had a few quarts added. I would like to change it and want to see the arguments of spending the big bucks for OEM oil or I believe Type F?

You can use what ever you want, it is your tractor.

BUT....here is what is tried and true and recommended..... Hydro Fluids

Thanks for the help
