436 Hours With all fluids changed as required. All fluids full. Tractor sits long times between use. Shuttle was fine coming out if barn then Forward didn't work. Reverse shifted okay. Neutral was fine. Now Reverse and Neutral are Reverse and Forward is Neutral. Checked the Shuttle switch on column and it's okay. I'm old and don't want the Caterpiller Dealer to dent my retirement any answers before I sell a kidney?
