Hey guys, I do not usually pop in on anything other than Case cause that is where I spent my life, BUT, I had a man on the Case forum who used an off brand oil in his transmission, every lined friction plate assembly in the power shift, the diff lock and PTO shed its lining just like you have pictured, causing him thousands of dollars to replace the lined plates. We recommend that our customers stay with Case oils and filters, As far as filters, I believe Case and John Deere share the same manufacture as we were a Case/ JD lawn and garden dealer and we used JD filters which were identical in design. , Back to oil, I would recommend the same for you guys as I believe HYGARD is probably recommended for that unit, not knowing JDs oil specs I could be wrong but I would use JD brand oil, BTW, I have high regard for HYGARD and believe it too be on a par with Cases HYTRAN and would not be afraid to run it in a Case product.
