Depending on how many hours are on this machine it may be a disadvantage to recalibrate, sometimes the pumps/motors may be so out of whack it opens a new can of worms....with that being said pull the cover off the TCU behind your left elbow, should be 6-7 7mm head screws. Key on engine off id scroll till you see codes and select that till it shows "END" hold select down on end and that will erase all codes and flash F300. Scroll back to "CAL" and I can't remember if you hold select down on CAL and start machine or start machine and then hold select on CAL. Try either of those that work and it should flash the software version and then it'll give you steps to follow on the TCU window. Should show Park at first and then if you lower park lock lever should go through all steps. DecH and DecL low is decel pedal high and low, then Rstr and Lstr are right steering and left steering before you go into counter rotate, Rctr and Lctr are going into counter rotate on each side, ThrH and ThrL are throttle high and low. DecB is decel brake going to the first stop of pedal. Up and Dn are transmission speed lever, For and Rev are forward and reverse... Once and if you complete all the sensor calibrations should go through a pump/motor section, it'll tell you to ThrH and leave it high and then you move joystick into forward and let it do its thing then into reverse and let it do its thing, then pumps are done should have you set trans speed somewhere and travel forward and reverse in low spd set trans spd higher and travel forward and reverse in high spd. Should be all done after that. When going through sensor calibrations be sure to move joystick, pedal, throttle level, slow and steady to stops, may take a couple tries of playing with it before it'll go through. Make sure low engine spd is 875-925 rpms and high speed shouldn't be over 2400 rpms before you start all this stuff otherwise it'll never work.
