I have 2 hyster forklifts that spec John Deere J20A fluid for their monotrol automatic transmissions. I Have been using Mystik Universal Trans Hydraulic and Traveller® Universal Tractor Trans/Hydraulic Fluid that meats the J20C spec. Is their something better for the montrol system? Preferably Something from Chevron Or Mobil as those are the two most easily acquired brands locally. Please NO Amsoil or Shaffers recommendations Keep it to easily acquired major brands.
