Start with the machine in front of you.

A guide should help you verify, not simply repeat a claim.
When a detail depends on a specific year, transmission, market, or serial range, the guide will say so. For repair, lifting, towing, or parts work, always confirm the exact machine against the appropriate operator, service, or parts manual.
