Trans Adapter Cummins

The Trans Adapter Cummins from G FORCE CROSSMEMBERS is a precision bellhousing adapter designed to mate modern automatic transmissions with Dodge Cummins diesel engines. This adapter solves a critical compatibility challenge for engine swaps, custom builds, and performance upgrades by bridging the gap between late-model transmission housings and Cummins engine blocks. Whether you're building a high-torque diesel platform or restoring a classic truck with modern driveline components, this adapter is essential for seamless mechanical integration.

Constructed from lightweight aluminum, the Trans Adapter Cummins reduces unsprung weight while maintaining robust structural integrity under the extreme demands of diesel powerplants. The adapter accommodates three industry-standard transmissions—the TH400, 700R4, and 4L80E—making it versatile across multiple application scenarios. A flexplate is included, eliminating the need for separate purchasing and simplifying installation. The aluminum construction resists corrosion and thermal stress, critical factors when operating in close proximity to high-heat engine components. Weighing 30.92 lbs with compact dimensions of 18.05 x 5.3 x 22.05 inches, it balances durability with practical fitment in tight engine bays.

This adapter benefits diesel enthusiasts, custom fabricators, and performance builders seeking reliable drivetrain solutions for Cummins-powered vehicles. Installation requires precise alignment and proper torque sequencing; work with experienced technicians familiar with bellhousing adapters to ensure optimal results. The included flexplate eliminates guesswork during assembly, reducing labor time and installation errors. Compatible with TH400, 700R4, and 4L80E automatic transmissions, this adapter is the foundation for bulletproof power delivery systems capable of handling modified diesel engines and demanding off-road or towing applications.
