PARTS INFORMATION

NOTE:
Reference the Tool Catalog Price List in ASIST. Pro-rate the individual connectors, terminals, retainers and/or seals used per this list, then multiply that pro-rated amount by 40% (dealer mark-up) to arrive at the claimable amount for the repair component(s) actually used. On your warranty claim, use Part Category 791 ("Body Electrical") to claim the derived amount.

CLAIMS INFORMATION





If only the connector is repaired or if the connector is repaired and the valve body is replaced (including Transmission Control Unit Reprogramming and initialization), submit a Primary Failed Part (PP) line claim using the claims coding table.
