TH400 To 82-93 S10 Transmission Mount

The TH400 to 82-93 S10 transmission mount by TRANS-DAPT is purpose-built for mechanics and enthusiasts performing serious drivetrain swaps on second-generation Chevrolet S-10 compact trucks. This solid steel mount bridges the gap between the legendary TH400 three-speed automatic transmission and the original mounting points of 1982–1993 S10 chassis, enabling a robust upgrade path for those seeking increased towing capacity, durability, and torque handling. Whether you're building a street machine, restoring a classic compact truck, or upgrading from a weaker original transmission, this adapter mount delivers the structural foundation your swap demands.

Machined from solid steel and finished in durable black paint, the TH400 to 82-93 S10 transmission mount eliminates flex and vibration that compromise drivetrain longevity. The TH400 is legendary for its ability to absorb punishment—rated for over 450 lb-ft of torque in stock form and scalable far beyond with proper tuning—yet its original mounting footprint differs significantly from the S10's compact design. This TRANS-DAPT adapter resolves that mismatch with precision engineering, ensuring perfect alignment between the transmission's bell housing and the engine block while maintaining proper ride height and driveline geometry. The solid construction prevents the harmonics and NVH (noise, vibration, harshness) that rubber isolation mounts introduce under load, critical for high-horsepower builds where transmission creep can cause misalignment and premature wear.

S10 owners pursuing big-block swaps, fuel injection conversions, or transmission upgrades will find this mount indispensable for maintaining stock appearance while gaining performance. Installation requires standard hand tools and basic mechanical competency; the mount bolts directly to both the original S10 crossmember provisions and the TH400 case without cutting or welding. Proper torque sequencing and alignment checks ensure maximum service life and eliminate clunk or movement during gear changes and hard acceleration. This is a critical component—not a convenience item—that separates amateur builds from professional-grade conversions.
