Cadillac CTS-V 6L90E Transmission Mount Adapter for LS and LT Engines
The Cadillac CTS-V 6L90E Transmission Mount Adapter solves the challenge of mating the 6L90E tailshaft housing to the standard crossmember on CTS-V models from 2009 to 2014 when swapping LS or LT powerplants. Crafted from premium materials, it maintains precise alignment under heavy loads and simplifies fitment during engine conversions. Installation follows a straightforward bolt in procedure with clear instructions for a stress free setup that delivers reliable integration across LS and LT platforms.
Engineered Precision for Crossmember Alignment
This adapter is machined to match the 6L90E tailshaft housing footprint exactly to the 2009-2014 CTS-V crossmember mount, guaranteeing true centerline alignment under load. Tight tolerances minimize drivetrain lash and vibration by eliminating any offset that can lead to shifting under torque. With an accurate fit between transmission and chassis, gear engagement feels sharper and throttle response is more consistent. The precise interface also reduces stress on surrounding mount points, preserving the integrity of the factory crossmember.
Premium Materials Ensuring Lasting Durability
Constructed from durable, high-strength alloy, this adapter stands up to the elevated torque and heat cycles typical of LS and LT swaps. The material's yield strength and tensile properties were selected to resist deformation and fatigue over repeated power applications. Its robust design maintains mounting geometry even under extreme driving conditions, preventing warping or loosening that can plague lesser components. As a result, you gain a wear-resistant mount that delivers reliable performance throughout the life of your build.
Flexible Integration with LS and LT Platforms
Designed to accommodate both LS and LT small-block Chevrolet powerplants, this adapter handles variations in bellhousing depth and tailshaft flange orientation without extra machining. You can move between LS and LT engines without concern for clearance conflicts in the engine bay. This versatility lets builders explore different power configurations while maintaining a clean installation. By covering multiple engine families in one piece, it reduces the need for custom brackets and saves valuable workshop time.
Bolt On Installation for Stress Free Setup
The bolt on design uses existing CTS-V crossmember holes and 6L90E mounting points, requiring only common hand tools for assembly. Clear instructions guide you through each step, and no cutting or drilling is needed on the transmission housing or frame. All hardware aligns without force, offering a stress free process even for first time installers. Once the adapter is secured, you can move directly to plumbing and wiring, streamlining the entire swap timeline.
Engineered for precise alignment and lasting reliability in your LS or LT swap.
