Dual LS and LT 6L90E Transmission Mount Adapter for Cadillac CTS-V
When fitting an LS or LT powerplant into a 2009 to 2014 CTS-V chassis, installers often struggle with aligning the 6L90E transmission tailshaft housing to the stock crossmember. The Cadillac CTS-V 6L90E Transmission Mount Adapter provides CNC machined interfaces that match the tailshaft housing to factory rails within thousandths of an inch. It secures directly to existing crossmember bolt holes and preserves chassis geometry under torque loads, which reduces vibration and maintains predictable handling. By accommodating both LS and LT engine families in a single unit, this adapter simplifies parts inventory and cuts installation time without extra brackets or cutting operations.
CNC Machined Alignment for Precise Crossmember Fit
The adapter's CNC machined interface delivers alignment accuracy within thousandths of an inch, ensuring the 6L90E tailshaft housing sits perfectly on the factory crossmember rails of your 2009 to 2014 CTS V chassis. This level of precision preserves the original chassis geometry under heavy torque loads, preventing distortion that can lead to driveline vibration or unwanted noise. By holding the transmission in true centerline position, throttle response remains crisp and handling balance is maintained from street cruising to track sessions. Installers appreciate how this approach removes the need for makeshift supports or trial-and-error adjustments, streamlining the engine swap process and boosting overall reliability.
Premium Materials for Durability Under Load
Constructed from a high grade aluminum alloy selected for its excellent tensile strength and fatigue resistance, this transmission mount adapter stands up to repeated torque spikes and thermal cycling without deforming. The material's inherent ability to dissipate heat helps protect surrounding components while preserving dimensional stability over time. Unlike generic cast parts that can develop stress cracks, this alloy blend resists bending and maintains snug fitment even after thousands of miles. Builders gain confidence knowing the adapter will endure the most rigorous driving conditions, whether climbing steep grades, launching from a dig, or enduring track laps at sustained RPM.
Effortless Fitment Using Factory Mount Points
By utilizing the stock bolt locations on the original crossmember, the adapter eliminates any requirement for cutting, welding, or aftermarket brackets. Integrated alignment bosses and clear step-by-step instructions guide the part into perfect position, allowing technicians to complete the installation with common hand tools in minimal time. This streamlined process reduces the likelihood of errors that can cause misalignment or introduce vibration. Whether you’re a professional shop or a dedicated enthusiast, the straightforward design minimizes downtime and avoids the frustration associated with custom fabrication, making the LS or LT swap far more accessible.
Versatile Compatibility Across LS and LT Powerplants
Designed to bridge the dimensional differences between LS and LT engine families, this adapter accommodates variations in bellhousing depth and flange orientation without any additional modifications. Swap planners benefit from a single solution that works with small block Chevy and newer Gen V architectures alike, cutting parts inventory and reducing the potential for ordering mistakes. This versatility allows quick transitions between engine platforms, whether you’re testing blend ratios or finalizing a performance build. With one adapter covering multiple configurations, project timelines shrink and budget predictability improves, giving builders more time to focus on tuning and driving.
Engineered for precise alignment and lasting reliability in LS or LT swaps, this adapter ensures smooth drivetrain integration and consistent chassis geometry.
