3-4 Speed Auto Shifter

The MR. GASKET 3-4 Speed Auto Shifter (SKU MRG7668) is a floor-mount automatic transmission shifter engineered for vehicles equipped with 3 or 4-speed automatic gearboxes. Built for enthusiasts and performance shops seeking precise shift control without the complexity of aftermarket electronic systems, this shifter transforms the stock driving experience by delivering crisp, direct engagement at the transmission lever. Whether you're building a street machine, resto-mod, or upgrading a classic muscle car, this unit provides the mechanical feedback and reliability that serious automotive technicians trust.

The 3-4 Speed Auto Shifter utilizes a robust floor-mount design that integrates seamlessly with your vehicle's transmission crossmember and drivetrain architecture. This mechanical linkage system eliminates unnecessary play and reduces response lag compared to worn OEM shifters, allowing drivers to feel and control each gear selection with confidence. The shifter's steel construction and precision tolerances ensure years of dependable service, while the compact footprint—measuring 8 x 4 x 20.4 inches and weighing just 7.45 lbs—fits within most transmission tunnels without intrusive modifications. The kit includes all necessary hardware and mounting provisions for straightforward installation on compatible 3 and 4-speed automatic platforms.

This shifter is ideal for hot rod builders, vintage car restorers, and mechanics upgrading vehicles with older automatic transmissions including Turbo 350, Turbo 400, and comparable gearboxes. Installation requires basic mechanical knowledge and standard hand tools; proper alignment of the transmission kickdown linkage and column cross-shaft ensures optimal shift quality and prevents binding. The MR. GASKET 3-4 Speed Auto Shifter excels in applications where stock shifters have worn, or where aftermarket refinement enhances both functionality and aesthetic appeal. Verify your transmission type and vehicle year before ordering to confirm compatibility with your specific floor pan and transmission tunnel geometry.
