Transmission Hump - Plastic - 4-Speed - 68-72 Cutlass

Description

Transmission Hump – Plastic – 4-Speed – 1968–1972 Cutlass

The Transmission Hump – Plastic – 4-Speed is an OE-style interior and floorpan restoration component designed for 1968–1972 Oldsmobile Cutlass models equipped with a manual 4-speed transmission. This reproduction shifter hump replaces the original shifter opening section in the transmission tunnel, restoring the correct pass-through area for the shifter to extend from the transmission into the passenger compartment. It is also suitable for automatic-to-manual transmission conversion projects where a factory-style shifter opening is required.

From the factory, Oldsmobile produced the original transmission humps in stamped steel. Over time, these sections are often damaged, rusted, cut, or missing—especially on vehicles that have undergone drivetrain changes. This reproduction hump provides a clean, accurate solution for restoring or modifying the shifter opening without altering surrounding structural floorpan sections.

Manufactured as a molded plastic panel, this transmission hump is designed specifically for a non-structural area of the floor pan. The molded construction offers an ideal balance of durability, corrosion resistance, and ease of fit while maintaining the correct shape and clearance for 4-speed shifter applications. The panel follows the proper contours of the transmission tunnel and positions the shifter opening correctly within the cabin.

This part is produced by OPGI under the RESTOPARTS® brand and is offered through Auto Metal Direct as a third-party OE-style solution. It is intended for use on Cutlass models requiring a 4-speed shifter hump replacement or manual transmission conversion while preserving a factory-style appearance inside the vehicle.
