There is a high demand for 4L80 transmissions. This case is because the technically savvy crown understands its real powers. The 4L60 transmission is the follow up of the TH400, and typically services heavy vehicles. 4l80e-transmissions/”>GearStar has transmissions of levels two, three, and four.
Why did 4L80 replace TH400?
This device has the same makings as the 4L60. The difference is that it works best with heavy loads. The first construction from General Motors was in 1991. The first version proved useful and sturdy up to 2013, before getting a replacement upgrade.
The increased popularity and favored strength were due to the notable duration of service, better consumption of fuel, and the capability to handle more torque. These settings made it possible for the transmission to fit perfectly in a high-powered engine.
Why is 4L80 better than 4L60?
The gear ratio makes the most significant difference between the two transmissions. The first gear of the 4L60E has a ratio of 3.059 to 1, while the first gear of the 4L80 has a ratio of 2.48 to 1. These details are critically important in establishing the performance of the car. People swap from the last of the 4L60 transmissions because they expect better functionality. The difference in the ratio has compensation from the rear axle differential.
The 4l80E has an oval shape while the 4L60E has a rectangular one. The designs mean that the 4L80E will utilize more bolts for installation than the comparison. The bigger and better size of the 4L80E adds to its durability capability.
The apparent difference is that the 4L60E is cheaper. This case is because of the better power support, which goes into supporting high-powered engines. The high price also corresponds with the strength of the device. The 4L60E breaks easily when swapped to replace a 4L80 transmission.
Should you buy the new or the old 4L80s?
The choice between the two depends on the functionality required. It is, therefore, necessary for you to consult the construction team of Gearstar for more specific recommendations.
- The difference between the new and old versions is they have different bolt hole locations for bell housing.
- The oil lines of the older models are nearer to the front
- The old models of 1992 to 1993 have wiring that follows the old style
Construction of the 4L80 transmission
The device handles up to 8000 pounds of GVWR, which is one of the most massive heavy-duty settings. The transmission has an extra load of 254 pounds, which is heavier than the 460LE, which applies to lighter applications.
The overdrive ratio of 0.75 to 1 provides a reduction in RPM. The setup then has a ripple effect on performance, which has significantly better efficiency. The 4L80E has a lock-up torque converter with a high stall speed and maximum multiplication of the torque. The combination complements the internal clutch. High cruising speed will not cause exceedingly high heat; hence, the efficiency is excellent for overdrive transmissions such as the following:
The Hughes performance has a transmission of 4L80E, which uses a variety of combinations for the engine and the power levels. The option is perfect for the horsepower of 850 and more.
