I need some suggestions on the next step in diagnosing my power shift problem. I have always had JD 6030's however, I recently took a chance and bought a 2590 case from a jd dealer (7000 hrs) . They are rare in south GA. I used it on a flail for 100 acres and everything
was fine with the transmission until now. It is a clean tractor with a good engine and A/C. Overall I have liked the tractor. Recently, it stopped hard and was jumpy upon moving then it went back to working. Now it
loads the engine in low range and stalls immediately in reverse. It does not load the engine in intermediate and high range; however, the trans oil light comes on in int and high range. It will grind gears and move in all forward gears. Stalls immediately in reverse.
I have changed trans filters. I have removed and polished each spool in tcv. I even removed entire tcv valve to replace the gaskets on each side. I replaced orings and checked all the valves and spools cleaning valve thoroughly. Each spool moves freely. I have IT manual. Not a lot of
mechanics that work on older cases here. Also the steering, pto, and remotes seem to work fine.
Any suggestions would be appreciated.
