Loader Backhoe Common Faults

 · The washer is maybe 1/16 or 1/8 tick and appears to be one of the thrust washers in the transmission. I can fix the transaxle but I'm very concerned about this loose washer. The ring and pinion gear teeth are in excellent shape. the unit seems to shift form forward and reverse ok but I wonder for how long. Any ideas would be welcome. Thanks!.
