Read articles →This is a hands-on repair video, not a review: a technician diagnoses a PTA fault code on a 6170R's IVT transmission, explains how the cold-start oil bypass valve works, then physically accesses and replaces the stuck thermal valve behind the cab floor plate. It covers diagnostic codes, removal steps, tool sizes, the $430 John Deere part cost, and clearing the fault afterward. Useful for owners facing this exact IVT code or valve failure.
Posted by a repair-shop channel (western truck and tractor repair) documenting an actual fix, with a technician's perspective on parts pricing and John Deere design issues.
