LS and LT Transmission Mount Adapter for Cadillac CTS-V 6L90E
Swapping a GM LS or LT engine into a 2009 to 2014 Cadillac CTS V chassis quickly runs into the challenge of matching the 6L90E transmission tailshaft housing to stock mounting points with consistent alignment. The Cadillac CTS V 6L90E Transmission Mount Adapter solves this by using precision CNC machined interfaces that bolt directly to original crossmember rails and hold the transmission centerline under high torque loads. Installers avoid time consuming modifications by using existing bolt holes and alignment bosses that lock the adapter into place without cutting or extra brackets reducing vibration and maintaining factory geometry. Plus compatibility with both LS and LT powerplants offers flexible sourcing for any engine swap plan.
Precision CNC Machined Surfaces for Consistent 6L90E Alignment
The Transmission Mount Adapter features interfaces cut with CNC accuracy, ensuring the 6L90E tailshaft housing seats exactly on the stock crossmember rails of a 2009 to 2014 Cadillac CTS V chassis. By holding alignment within thousandths of an inch, this piece preserves original chassis geometry under heavy torque conditions. The precise fit prevents drift that leads to driveline vibration or unwanted noise and helps maintain steady power delivery. Installers skip trial and error adjustments since alignment bosses lock the adapter in place without the need for temporary supports. This method sustains consistent handling balance from routine driving to spirited track use.
Robust Aluminum Alloy Construction for Enduring Strength
Constructed from a premium grade aluminum alloy selected for its high tensile strength and fatigue endurance, the adapter endures repeated torque loads and temperature cycling without distortion. The material also transfers heat away from the tailshaft housing, protecting both adapter and transmission seals from premature wear. Unlike generic cast parts, this alloy resists cracking and provides tight tolerance retention over extended service life. Builders benefit from a component that will not bend under stress or change shape after thousands of miles. Confidence in the mount's integrity lets drivers focus on performance rather than worrying about mechanical failure.
Streamlined Installation Using Factory Bolt Patterns
The adapter bolts directly to existing crossmember holes on the CTS V chassis without cutting or welding, so even complex transmission swaps can be completed with basic hand tools. Integrated alignment bosses guide the adapter into perfect position while detailed instructions walk installers through each step. This approach eliminates the need for extra brackets or custom fabrication, cutting overall labor time and reducing the risk of misalignment mistakes. Technicians of any skill level gain a repeatable process that delivers precise results on every install. The simplified fitment greatly reduces downtime for both professional shops and dedicated enthusiasts alike.
Unified Compatibility with LS and LT Engine Platforms
By bridging the dimensional differences between Gen III and Gen V powerplants, the adapter works seamlessly with both LS and LT engine families when using a 6L90E transmission. It accounts for variations in bell housing depth and flange orientation without requiring additional parts or modifications. Swap planners can consolidate parts lists and avoid ordering errors thanks to a single adapter solution that spans multiple engine architectures. This flexibility shortens project timelines, cuts build costs and allows quick transitions between different engine configurations. With one mount adapter covering a range of Chevy V8 platforms, focus shifts from part sourcing to tuning and driving.
A reliable solution for LS and LT transmission swaps with precise alignment and durable construction.
