I have a Cub Cadet 2518 with the hydrostatic transmission. I need some trans oil and don't want to travel 60 miles to a Cub dealer to get it. Is there any substitute I can use in the trans on this tractor? Thanks for the help..........

Thanks JMoe for a quick and clear answer. I am assuming that you have done this for a good while and my guess was right that the "only oil in the world that won't ruin it" is a scare tactic so they can get $10 per qt. (after I drive 60 miles)

That's my take exactly Catch. I did a bunch of research on it some years ago. You'll find the posts on this forum. I've had 15w40 in the trans for a few years and ~100hrs or so. You can also get the trans filter from Napa or Carquest; It's a direct replacement hydraulic filter. No cheaper than a dealer though. they're like $12.

That's really a great help. Thanks so much. My next research problem is how to substitute the trans oil for my 2008 Altima with the CV transmission. It never ends does it?

hy-tran at napa is 11.00 a gallon.
Not to say old school Hy-Tran wouldn't work, but AFAIK, Hy-Tran is a typical universal hydraulic fluid, which is essentially a motor oil in a 20wt variant with a manufacturer specific add pack (very minimal) and possibly dye colored. Very old school hydrostatic drives spec'd hydraulic fluids. Most anything lawn/garden tractor in the last ~25+yrs would not.
