BCHD PT4765 Automatic Transmission Extension Housing Seal

Overview

PT4765 is an automatic transmission extension housing seal for Ford, Lincoln, and Mercury applications with booted or boot-type fitments. It is listed across a wide range of rear-wheel-drive vehicles, including Ford F-150, Ford E-Series vans, and Lincoln Town Car applications.

Key Features

• Automatic transmission extension housing seal for sealing the extension housing area.
• Fitment covers booted and boot-type applications across multiple Ford, Lincoln, and Mercury platforms.
• Compatible with long-running service applications on Ford F-150, Ford Explorer, and Ford E-Series models.
• Part number PT4765 for catalog lookup and service matching.

Detailed Description

PT4765 is a transmission sealing component used in extension housing service where the output area requires a precise seal. The fitment data includes Ford F-150, Ford E-150, Ford E-250, Ford E-350 Super Duty, Ford Explorer, Ford Mustang, Lincoln Town Car, Mercury Grand Marquis, and related applications, with notes that distinguish booted, with boot, and boot type configurations. This makes PT4765 a relevant replacement when servicing the transmission tail housing on supported Ford, Lincoln, and Mercury vehicles. Use PT4765 when the application calls for the listed extension housing seal configuration and the vehicle-specific boot note matches the catalog entry.

Common Issues Addressed

• Transmission fluid seepage at the extension housing area.
• Seal wear from age, heat, and drivetrain movement.
• Leak concerns during transmission service or rebuild work.
• Fitment mismatch when the boot style does not match the original application.

Installation Notes

Confirm the exact year, make, model, and boot note before installation. Match the catalog note carefully, since the fitment includes multiple booted and boot-type variations. Inspect the extension housing surface and surrounding components for wear or damage before installing the new seal. PT4765 should be installed only on applications that match the listed fitment details.
