A rebuilt transmission can breathe new life into your vehicle. For the 4L60E transmission, a comprehensive rebuild kit is essential. This article explores the components of a master rebuild kit for the 4L60E, highlighting its features and benefits, particularly focusing on the Alto Red Eagle clutch kit.
The master rebuild kit for the 4L60E typically includes:
- New 4L60E Overhaul Kit: This comprehensive kit provides all the necessary seals, gaskets, and small parts required for a complete rebuild.
- Alto Red Eagle Clutch Kit with Powerpacks: This high-performance clutch kit is designed for enhanced durability and performance, featuring friction plates with superior wear characteristics.
- High Performance Kolene Steel Kit: This kit includes hardened steel components for increased strength and longevity in high-stress applications.
- New 4L60E Filter: A new filter ensures clean transmission fluid for optimal performance and extended transmission life.
- New 4L60E Bushing Kit: Replacing worn bushings ensures proper alignment and smooth operation of internal components.
- New 4L60E Thrust Washer Kit: New thrust washers maintain proper clearances within the transmission, preventing premature wear.
This complete 4L60E master rebuild kit includes the Alto Red Eagle clutches with a 3/4 clutch pack containing eight clutches. It includes everything necessary for a thorough transmission rebuild, from the filter and bushing kit to the thrust washer kit and a high-performance Red Eagle band.
Alto Red Eagle Clutches: The Heart of the Kit
The Alto Red Eagle friction material provides a consistent mid-point coefficient even under high horsepower conditions. Importantly, it offers superior friction wear characteristics compared to other brands, especially during high-energy engagements. Competitors’ materials can degrade thermally and physically at higher horsepower per square inch.
Performance Testing: Alto Red Eagle vs. the Competition
Rigorous testing demonstrates the superior performance of Alto Red Eagle clutches. A six-level high-energy test measured the pressure required to stop a flywheel in one second, comparing Alto Red Eagle to two OEM manufacturers (A and B). The lower the pressure required, the higher the frictional properties and performance of the clutch.
Six-Level High Energy Test Results
| Levels | Cycles | OEM A (lbs./sq.in.) | OEM B (lbs./sq.in.) | Alto Red Eagle (lbs./sq.in.) |
|---|---|---|---|---|
| 1 | 10 | 64 | 70 | 66 |
| 1 | 100 | 65 | 71 | 65 |
| 2 | 10 | 72 | 84 | 74 |
| 2 | 100 | 73 | 84 | 74 |
| 3 | 10 | 85 | 96 | 86 |
| 3 | 100 | 92 | 101 | 93 |
| 4 | 10 | 102 | 116 | 104 |
| 4 | 100 | 110 | 122 | 108 |
| 5 | 10 | 118 | 133 | 117 |
| 5 | 100 | 124 | 135 | 118 |
| 6 | 10 | 136 | 148 | 131 |
| 6 | 100 | 143 | 152 | 134 |
Consistently, Alto Red Eagle required less pressure, demonstrating superior frictional properties and outperforming both OEM manufacturers. This translates to better performance and longer life for your rebuilt 4L60E transmission.
Kinetic Energy and Inertia Levels in Testing
| Levels | Inertia (lb.-ft.²) | Kinetic Energy (lb.-ft.) |
|---|---|---|
| 1 | .261 | 30,232 |
| 2 | .302 | 35,048 |
| 3 | .344 | 39,865 |
| 4 | .385 | 44,681 |
| 5 | .426 | 49,498 |
| 6 | .510 | 59,131 |
The test involved six energy levels, each with 100 clutch engagements at 60-second intervals from 4600 RPM with a one-second lockup time. This rigorous testing ensures the Alto Red Eagle clutches can handle demanding conditions.
Investing in a master rebuild kit for your 4L60E transmission ensures a complete and high-quality rebuild. The inclusion of the Alto Red Eagle clutch kit guarantees superior performance, durability, and longevity for your transmission. This comprehensive kit provides peace of mind and ensures your vehicle is back on the road with a reliable and powerful transmission.
