• Improper sealing after transmission service
• Drips or seepage around the housing bore and shaft interface
• Maintenance needs on Hyundai, Kia, Mitsubishi, Chrysler, and Dodge automatic transmissions

Installation Notes and Tips

Verify the transmission code before installation, since fitment varies by engine and gearbox family. Confirm the shaft and housing bore dimensions match the service opening, and inspect the sealing surface for scoring or contamination before installing the new seal. Clean the bore thoroughly and lubricate the lip with clean transmission fluid during assembly.
