Case 450 Dozer not able to turn RIGHT

(quoted from post at 16:16:58 11/16/15)
Watch the pressure gage on the dash (transmission pressure) when making a shift from high to low range to go right the gage should dip and come right back up. if it does not I would look at the right hand spool in the control valve.

The spools were a two piece arrangement with a snap ring in a groove holding them together, I have seen them fail and the spool pieces separate and the spool not move. If you get a cooperative dealer you can get a replacement but they are not shown in every parts book that uses that spool. That tranny was used clear up through the series from 450 through 850 so searching the books to show a breakdown of the spool may be necessary, the later model year books are most likely to show a pic of it, HTH.

(quoted from post at 17:09:43 11/16/15) Your information was correct, the Right spool pulled all the way out w/o resistance and the keeper ring was in fact gone, what is the best way to take the valve apart to replace or find the ring clip...should I pull it from the tractor and then access it or ? ... and by the way...Thank you so much...
