Description

Swapping a Ford Modular engine into your 4WD truck demands a transmission that handles modern power while fitting the unique packaging requirements of a divorced transfer case setup. This customizable TKX package solves the challenge by positioning the front-shift TKX so both the transmission and transfer case shifters land nearly side-by-side—critical for 4WD trucks where bench seat clearance and dual-shifter ergonomics matter.

The TREMEC TKX delivers 600 lb-ft of torque capacity with 7,500 RPM shift capability, making it ideally suited for the high-torque output of Ford's 4.6L and 5.4L Modular engines. TREMEC designed the TKX case specifically for tight tunnel clearances, and the compact end-loaded design provides clearance in most transmission tunnels without floor modifications. Multi-cone synchronizers and hybrid synchronizer rings made of sintered bronze and carbon deliver smooth shifts at high RPMs, while the ribbed 3-piece aluminum housing optimizes NVH control with outstanding structural stiffness.

The front-shift configuration is specifically recommended for trucks with bench seats, positioning the shifter forward where your hand naturally falls. Available gear ratios let you match the transmission to your engine's power band and intended use—wide ratio (3.27 first gear) for towing and low-speed grunt, or close ratio (2.87 first gear) for highway cruising and better gear spacing. The single overdrive (0.72, 0.81, or 0.68 depending on ratio selection) reduces cruising RPMs, improving fuel mileage and making highway miles far more enjoyable.

This guided package includes everything for a complete conversion: transmission, Ford bellhousing, transfer case bracket, crossmember, transmission mount, hydraulic master cylinder kit, hydraulic release bearing, and all supporting hardware. The Ford wide pattern compatibility works with adapter plates for narrow pattern applications, ensuring proper fitment across Ford Modular engine swaps. All TREMEC transmissions are built from 100% brand-new OEM-quality components and backed by MDL's lifetime technical support.
