Restore the correct operating oil level and breather before returning the unit to service. - How does Dodge warranty evaluation work if a product fails?: Failed units go to Dodge's US plants for evaluation — about a week in transit plus one to two weeks of analysis, and you get the findings either way. Warranty covers workmanship and material defects; failures caused by the application (lubrication, installation) fall to the customer, but the failure analysis tells you the root cause so it doesn't repeat. - Why do Dodge gearboxes cost more than import brands?: Reliability is the product. Dodge TXT and Torque-Arm II reducers go through 15 quality checks before shipping, and Dodge manufactures its own bearings at its North Carolina roller-bearing and Tennessee ball-bearing plants rather than buying them in. You're paying for uptime.
