6R80/10R80 to NP205 Adapter

NP205 to 6R80/10R80 Transmission Adapter Housing

Modernize your drivetrain while retaining the strength of a Ford NP205 transfer case with this NP205 to 6R80/10R80 Transmission Adapter Housing. Designed to connect a Ford-style left-hand drop NP205 transfer case with a 31-spline input to 4WD versions of the 6R80 and 10R80 automatic transmissions, this adapter provides a straightforward solution for drivetrain upgrades and engine swap projects.

Engineered for proper fitment and drivetrain geometry, this adapter housing bolts directly to the transfer case without modification and is pre-clearanced for NP205 applications. Its compact 3-5/8-inch thickness helps minimize drivetrain length while allowing builders to take advantage of modern transmission technology, including the 6R80's deep 4.17:1 first gear ratio. This adapter is ideal for Coyote-powered builds, late-model transmission swaps, and upgraded drivetrains in classic Ford trucks and Broncos.
