3-4 Hi Perf Clutch Pack GM 4L60E & 700R4 Red Eag

The 3-4 Hi Perf Clutch Pack GM 4L60E & 700R4 is a purpose-built friction and steel assembly engineered for automatic transmission builders and performance enthusiasts who demand reliability in high-torque or modified engine applications. This clutch pack serves as a critical internal component within the third and fourth gear planetary assembly of GM's legendary 4L60E and 700R4 transmissions, handling power transfer during mid-range and highway cruising. Whether you're rebuilding a stock transmission, upgrading to handle additional engine output, or restoring a classic muscle car, this OEM-quality pack ensures consistent engagement and durability under demanding conditions.

This clutch pack assembly comprises eight steel plates and nine friction discs, a proven combination that balances apply feel with thermal capacity and longevity. The steel plates provide structural rigidity and heat dissipation, while the friction material delivers consistent torque multiplication without slippage or harshness. The 3-4 clutch pack specifically controls the transition and lock-up between third and fourth gears, where proper engagement pressure prevents tier slipping and maintains transmission efficiency. Precision engineering and OEM-grade materials ensure that gear transitions remain smooth regardless of driving conditions—from steady highway operation to aggressive acceleration or towing loads.

Transmission builders, restoration shops, and DIY mechanics working on 4L60E or 700R4 units will find this clutch pack essential for complete overhauls or performance upgrades. Compatibility spans both the GM 700R4 (found in carbureted and early fuel-injected vehicles through the 1980s) and the 4L60E (the modern electronically controlled variant used from 1993 onward). Installation requires transmission disassembly and proper torque sequencing to ensure correct pack positioning and apply pressure calibration. This kit ships at 2.9 lbs and fits within standard transmission case dimensions, making it a straightforward replacement for worn or damaged originals during any rebuild cycle.
