The Pioneer Automotive Automatic Transmission Output Shaft Seal is a replacement transmission seal. It sits at the output end of the automatic transmission, around the output shaft. It keeps transmission fluid in the case while the shaft turns. This part is also called an A/T output shaft seal, rear transmission seal, or driveshaft seal.

Key Features:

• Seals around the transmission output shaft to help prevent automatic transmission fluid leaks
• Pioneer describes its transmission components as exact fit, no-compromise replacement parts
• Gaskets and sealing systems part type, made for automatic transmission service
• Backed by Pioneer, a name in the automotive aftermarket for over half a century

A worn or brittle output shaft seal can leak fluid. This can lead to low fluid levels and extra wear on internal transmission parts. Replacing the seal restores the fluid barrier at the output shaft. It helps protect the transmission and keeps it properly lubricated. Pioneer offers this line in several part numbers to cover different applications.
