• Reassembly issues when replacing the front pump assembly

Installation Notes and Tips

Clean both mating surfaces thoroughly before installation and inspect the pump and case for nicks, warpage, or old gasket material. Verify the transmission application against the vehicle year, make, and model before assembly. For front pump-to-case applications, align the gasket carefully to maintain a uniform seal.
