4L60E PERFORMANCE TRANSMISSION OVERVIEW

The 4L60E represents GM's evolution of the legendary 700R4, introducing electronic control to enhance shift quality and power management. This transmission, while often criticized in stock form for its limitations, becomes a formidable performance unit when properly built. Our experience spans thousands of builds, from mild street performance to full competition applications.

COMMON FAILURE POINTS (STOCK):
• 3-4 Clutch Pack
• Input Shaft
• Sun Shell
• Forward Drum
• Servo Assembly

PERFORMANCE SOLUTIONS:
Through extensive testing and track validation, we've developed three distinct build levels addressing these weaknesses. Each stage incorporates progressively stronger components, with our Stage 3 builds capable of handling 800+ horsepower when properly supported.

KEY IMPROVEMENTS:
• Billet input shafts eliminate twist under load
• Carbon fiber bands provide superior holding power
• Updated valve body calibration for crisp shifts
• Heavy-duty servo assemblies prevent band failure
• Monster sun shell design prevents planetary failure
