Timken SL260123 Automatic Transmission Output Shaft Seal - Left

Timken SL260123 Output Shaft Seal

Timken SL260123 is an automatic transmission output shaft seal built to help retain lubricant and block contaminants at the transmission exit point. It is a direct-fit sealing component for select Hyundai and Kia vehicles, including Hyundai Palisade, Santa Fe, Sonata, Accent, and Elantra, plus Kia Sedona, Sorento, Telluride, Cadenza, and related applications.

Key Features

• Precision sealing design helps control oil and grease leakage at the output shaft
• Reinforced outer case resists installation damage and adds durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections and supports positive seating
• Internal contamination exclusion system helps keep debris out of the seal area
• Vent holes promote lubricant flow around the seal lip to reduce heat buildup
• Cross-references National 710997 and SKF 14452A for the same application

Detailed Description

This Timken transmission seal is engineered for the output shaft location where consistent sealing is critical to transmission performance. The SL260123 uses a reinforced case and a ribbed inner diameter to improve fit at the shaft surface, while its contamination-control features help reduce the risk of leakage caused by debris intrusion. It is a practical replacement for vehicles such as the Hyundai Sonata and Kia Sorento when the original seal shows wear, hardening, or seepage.

What It Helps Address

• Transmission fluid seepage at the output shaft
• Contamination entering the seal area
• Seal wear from heat buildup
• Poor sealing from minor shaft surface imperfections
• Leak-related drivability concerns tied to low lubricant level

Installation Notes

Inspect the shaft surface, seal bore, and surrounding components before installation. Clean the sealing area thoroughly and verify the seal is seated evenly to avoid distortion. For Hyundai Palisade, Santa Fe, Sonata, Accent, Elantra, and Kia Sorento, Telluride, Sedona, and Cadenza applications, confirm left-side placement before installation.
