Product Details

The ATP CO-4 is a precision-engineered automatic transmission oil pump seal designed to prevent fluid leaks and maintain proper transmission operation. This seal creates a critical barrier between the transmission oil pump and housing, ensuring consistent hydraulic pressure for smooth gear shifts and optimal transmission performance.

Key Features:

  • Exact fit replacement for OE specifications
  • High-quality seal material resistant to transmission fluid and heat
  • Prevents oil pump leaks and maintains proper fluid pressure
  • Designed for reliable sealing in demanding transmission environments
  • Direct replacement part for worn or damaged original seals

ATP Transmission Seals and Gaskets are manufactured to meet or exceed original equipment standards, providing reliable leak protection and long service life. This seal is an essential component during transmission rebuilds or oil pump service.

Fast Shipping and the lowest price on the Husky Floor Liners. I searched all the internet and this place had the best price. Shipping was not free but it was still cheaper than anywhere else with free shipping at those sites.
