Warranty
ATS LIMITED PRODUCT WARRANTY
ATS Transmission packages carry a ONE to FIVE YEAR Warranty. There are several exceptions, so refer to the Warranty’s specific terms and conditions . All labor, shipping, or any other charges associated with the product and the product’s failure are not covered under Warranty. Labor and/or shipping charges will not be refunded under any circumstance. After the one-year anniversary date of the original purchase, there is a limited parts replacement Warranty only. Transmissions that are purchased separately outside of a transmission package / stage and are installed without an ATS torque converter carry a 1 year parts only warranty and there is no labor or shipping allowance for transmission only purchases.
In the event of a product failure, the consumer must return the defective product to ATS for inspection before a replacement is sent to the consumer. After ATS inspects the product and completes the failure analysis, the inspection officer at ATS will provide written documentation stating the condition of the product and determine, to the best of his or her ability, what caused the malfunction or complaint. Based on the findings of the inspection report, ATS will determine whether there is a valid Warranty claim. Should a consumer require immediate service, and chooses not to wait for their product to be returned to ATS for inspection, service, and potential repair or replacement, the consumer can purchase a replacement product from ATS. The consumer must pay the full current MSRP, the applicable core charge, and shipping to and from ATS’ shop. When the defective product arrives, ATS will refund the core charge and inspect the product. During inspection, ATS will assess the product for warrantable damage. If the original product has indeed failed under the terms of the original Warranty, ATS will refund the full purchase price for the replacement product only. If the product has failed due to any issue not covered under the original Warranty, ATS will assess charges to the consumer based on any parts necessary to return the product to nominal ATS standards. ATS will deduct the total cost of required parts from the replacement product’s purchase price, and the consumer will be refunded the difference (if any) between the purchase price paid for the replacement product and the cost of parts.
If the consumer can wait for their product to be returned to ATS for inspection, service, and potential repair or replacement, the consumer pays shipping to and from ATS’ shop. When the defective product arrives in Colorado, ATS will inspect the product. ATS will then assess the product for warrantable damage. If the product has failed under the terms of the original Warranty contract, ATS will repair or replace the product – at ATS’s discretion. If the product has failed due to any issue not covered under the original Warranty, ATS will assess charges to the consumer based on any parts necessary to return the product to nominal ATS standards. ATS will bill the consumer for the total cost of parts required for repair of the product, and shipping to and from Colorado, prior to the repaired/replaced product being sent to the consumer.
