Valley Truck Parts is a authorized Allison warranty center. If Allison can trust us you can to!

Valley’s Rebuild departments have developed a thorough and consistent approach to customer satisfaction based on the following process:

Core exchanges or returns are first identified by model, part, and serial numbers, which are documented on a work order along with the name and account number of the customer. The information is entered into a database and is cross referenced to the original unit purchased. This process insures a “like for like” match. If there are discrepancies the customer is notified of the concern: (Mismatched units can affect the overall life of the transmission).

All core returns are completely disassembled and issued a “Cause of Failure” document. This is a very important process. If the Cause of Failure is externally related: (Shock Load, Driveline vibration, engine or abusive operation), we disclose to the customer the Cause of Failure. Upon request the old parts and cause of failure document is sent to the customer.

After Disassembly, all parts are thoroughly cleaned in the state of the art sonic cleaner. All Seals, Gaskets, Bearings, Bushings, and Friction clutches are disposed of and the remaining qualified parts are instrumented to meet Allison Transmissions rebuilt specifications and updated needs. Replacement parts are OEM certified and the original core retains its identity: (assuring no mass teardowns and units rebuilt from left over’s)

All rebuilt units are thoroughly tested for pressure flow, leaks and gauged to Allison testing specifications. The results are documented and available upon request from the customer purchasing the rebuilt unit. Only after successfully passing the Quality Assurance Testing process is the unit added to inventory for sale.

      
All of Valley Truck Parts rebuilt Allison Transmission are dyno tested to insure quality.
