GM Torque Converter 700R4 Lock- Up 2200-2800

The GM Torque Converter 700R4 Lock-Up 2200-2800 from ACC Performance is a precision-engineered transmission component purpose-built for high-performance 700R4 automatic transmissions. This lock-up torque converter is essential for operators and enthusiasts who demand seamless power delivery and fuel efficiency in vehicles equipped with General Motors' iconic 700R4 four-speed automatic, whether for tactical fleet vehicles, pursuit-rated law enforcement units, or performance restorations.

The Night Stalker lock-up design activates within the 2200–2800 RPM stall range, allowing the converter to mechanically lock the turbine to the impeller for direct engine-to-transmission engagement once optimal operating temperature is reached. This engineering reduces fluid slippage, minimizes heat generation, and improves fuel economy during highway cruising—critical factors in extended operational deployments or long-distance vehicle missions. The 10.750 inch bolt circle provides OEM-spec fitment, ensuring drop-in compatibility without modification to existing bellhousing architecture or mounting provisions.

This converter is ideal for fleet maintenance supervisors, transmission specialists, and vehicle platform custodians who need reliable, stock-footprint torque conversion technology. Installation requires professional transmission service and dynamic balancing to factory specifications. The 41.53 lb unit meets all OEM dimensional tolerances and is backed by ACC Performance's reputation for precision manufacturing in the transmission aftermarket. For vehicles relying on 700R4 transmissions in duty or performance applications, this lock-up converter delivers the mechanical synchronization and thermal management necessary for sustained reliability.
