GM Torque Converter TH400 2800 - 3200

The GM Torque Converter TH400 2800 - 3200 by ACC PERFORMANCE is a purpose-built fluid coupling designed for street and light-duty performance applications using the Turbo 400 transmission platform. This torque converter bridges engine output and transmission input, allowing the engine to idle independently while the transmission remains engaged—a critical function in both stock and modified vehicle builds. Field-proven by mechanics and performance enthusiasts, this unit delivers controlled power transfer at its specified 2800–3200 RPM stall range, making it ideal for vehicles requiring responsive launch characteristics without excessive parasitic loss during cruising.

The GM Torque Converter TH400 2800 - 3200 features an 11.500-inch bolt circle that mates directly to standard TH400 bellhousings and crankshaft flanges, ensuring drop-in compatibility with OEM and aftermarket applications. The 2800–3200 RPM stall specification means the converter locks at engine speed within this band, optimizing throttle response and fuel efficiency under normal driving conditions while providing adequate slip for controlled acceleration. Weighing 22.1 pounds, the unit is engineered with premium internals to withstand repeated thermal cycling and high-torque inputs typical of street performance duty.

The GM Torque Converter TH400 2800 - 3200 is best suited for street-driven vehicles with mild to moderate engine modifications seeking improved acceleration feel without excessive slip heat or transmission stress. Installation requires removal of the transmission and torque converter assembly; professional installation is recommended to ensure proper balancing and bolt torque specifications. Verify your vehicle's crankshaft flange and bellhousing configuration before purchase to guarantee fitment with your specific TH400 application.
