John Deere 755B Transmission Control Valve

The 755B and 655B are very close in the way the control valve works.

You will need to drain the reservoir or hook up a vacuum pump to hold oil in there. Then disconnect the linkage (B-F). Take out the cap screws and washers (A). Slide control valve toward the front of the unit.
Take out the lines (J-O). Shut off all openings using caps and plugs. Take the valve out of the unit. Put the valve on the unit. Then connect lines (J-O). Make sure the cap screws are good and tight (G). Put the cap screws and washers back on (A). Put the link back on (B-F). Lastly check all the linkage adjustments and you should be good to go.
