A shift kit can help your 4l60e transmission run more smoothly, but there are a few things to think about before doing so. When most individuals think of installing a shift kit in their automobile, they picture sudden and jarring gear shifts. While this is possible if you want it, the truth is that a 4l60e shift kit will not only benefit you but also improve the function of your transmission.
What Does A Shift Kit Do For A 4l60e?
Adding a shift kit to your 4l60e-equipped truck, vehicle, or SUV will cure and enhance the sluggish shifting that the 4l60e is recognized for in factory form. Shifts that are correctly installed will be more solid and quick without making it seem like you’ve been hit by a locomotive. This, like a corvette servo upgrade, may help extend the life of your transmission by decreasing slip between shifts. This is especially beneficial in applications that require performance or towing.
A side-by-side comparison of the 4L80E and 4L80E transmissions performances shows that they are distinct from one another. These gearboxes have various characteristics that distinguish them even though they be similar in some regard. Examples can include being produced by the populous General Motors Company. Alternatively, they can also be employing a 4-speed automated overdrive.
The 4L60E was initially utilized in vehicles with rear-wheel drive and appeared in these trucks from 1993 onwards. The 4L80E, on the other hand, was popular among diesel and big block vehicles. The 4L80E is also a more powerful transmission than the 4L60E. Let’s compare the performance of the 4
The 4L60E and 4L80E performance transmissions have many distinctions, including origin, size design, and weight, gear ratios, power, price, and so on. However, it’s worth noting that the letter in either name stands for four speeds.
The 80 in the 4L80E indicates that the engine may handle 8000 pounds of GVWR, whereas the 60 in the 4L60E implies that the gearbox can handle 6000 pounds of GVW. Furthermore, both names end with E, which means they are electronically managed transmissions. Here’s a detailed look at how they differ:
The 4L60E and 4L80E have the same model names. However, these transmissions were produced differently. The 4L80E is an electronic overdrive that succeeded the Turbo 400, which was a drag racing and hot-rodding transmission.
The 4L60E is a computerized transmission, taking the position of the 700R4. Starting from 1982, the 700R4 was the standard gearbox in Chevrolet and GMC automobiles.
By looking at the transmission fluid pan of a 4L80E and a 4L60E, you can tell them apart. The 4L80E has an oval-shaped pan, whereas the 4L60E has a rectangular one.
The number of bolts used to attach the transmission to the engine is also an issue. Because of its larger size, the 4L80E requires more bolts than the 4L60E. The 4L80E has a gasket with 17 bolts, while the 4L60E’s pan has 16.
Size & Weight
The 4L80E and the 4L60E are not identical, despite their similar names. The overall size and weight of each unit are quite different. The 4L80E is heavier and larger than the 4L60E (236 lbs versus 212 lbs). The 4L60E, on the other hand, weighs 150 pounds (without fluid) and has a length of 23.5 inches.
The 4L80E is considerably larger and heavier than the M90, which should come as no surprise. The amount of fluid these systems can handle is determined by the torque converter that will be used with the transmission.
The 4L60E is less powerful than the 4L80E, of course. To that end, this gearbox is frequently used in cars with strong engines. These are essentially the kind of vehicles that are utilized in demanding applications such as racing or towing.
If the 4L60E automatic transmission is employed in these power plants, the engine may only wear down the transmission largely because of its internal power. A stock 4L60E transmission, on the other hand, may sometimes support an engine.
Because the 4L80E is the more powerful of the two and can handle more demanding applications, it is more expensive than the 4L60E. Its higher price may be attributed to its bigger size and application in larger-displacement engines with greater horsepower.
The 4L80E is a popular choice for heavy trucks and high-speed vehicles because it’s durable and can handle a lot of stress. If you choose the 4L60E for an engine with significant horsepower, it may break.
The 4L80E is more costly because it is less popular than the 4L60E. With the 4L60E, locating parts and full transmissions is simpler than with the 4L80E. Whatever the case may be, you can get components for your 4L60E from an online source or a junkyard.
The duration of each transmission also varies. In terms of performance, their durability is proportional to the size of the internal components that they contain.
The maximum torque that the 4L80E and 4L60E are capable of handling is 450nm and 350nm, respectively. Nonetheless, these figures are not set in stone and may vary somewhat. In addition, because new transmissions tend to last longer than ones that have been in use for 30 years,
Wiring, Sensors, and Controller
The electrical systems of the 4L80E and 4L60E are also distinct. In this case, there is a difference in the wiring harnesses for the transmissions and the transmission control unit. When these components are mixed with each other in another gearbox, they are incompatible.
Another distinction is that the 4L80E incorporates two different types of sensors, whereas the 4L60E has only one. When swapping one transmission for another, it’s also a good idea to get a harness and control unit.
