Auto Transmiss Parts 759033 Automatic Transmission Extension Housing Seal

The Auto Transmiss Parts 759033 is an automatic transmission extension housing seal, also called a rear output shaft seal or tailshaft seal. It fits where the output shaft leaves the transmission housing. It keeps transmission fluid inside the case and keeps dirt and contaminants out.

Key Features:

• Automatic transmission extension housing seal (A/T seal) for the rear output shaft area
• Helps prevent transmission fluid leaks at the tailshaft and driveshaft connection
• Metal-and-rubber construction, as is typical for extension housing seals, for a press-fit installation
• Replaces a worn or leaking seal, helping maintain proper fluid level and smooth shifting

Replacement usually means removing the driveshaft, pulling the old seal, and driving the new seal in evenly with an appropriate seal driver. Replace this seal if you see fluid dripping from the rear of the transmission, or if you smell burnt fluid.
