JD 550 G shifting from forward to reverse with out shifter moving? Anyone else have this problem?
Welcome to HEF Bernie . IIRC, there is no detent mechanism on the transmission control valve directional spool. I suspect there is a bunch of loose joints and excess play in the directional control linkage. Link to the control breakdown from Deere parts page. https://partscatalog.deere.com/jdrc/sidebyside/equipment/77456/referrer/navigation/pgId/77212337
Screenshots of transmission controls adjustment procedure. . .
thanks I will check this out.
turns out it was the brake engaging because of sloppy linkage. Thanks for your help
FYI there is a directional selector bellcrank that has small ball bearings in it that caused this problem also. Deere provided a kit to correct this problem in early SR# and put it in production in later SR# if problem returns I can send you pictures and part numbers.
thank you.
