8L90E

If your vehicle's transmission has seen better days, it's time to upgrade to a new 10-speed automatic. GM uses the 8L90E and 8L45 in their midsize pickup trucks, as well as in their cars. They are known for their strange shifting tendencies and lurches when coasting or coming to a stop light. This transmission will need to be replaced soon if you want to enjoy better gas mileage.

GM has always led the way in transmission technology, and this latest addition to their lineup is no exception. Unlike previous 8-speed transmissions, these new units have extra gears, helping meet emission standards and increase fuel efficiency. The only problem is, this newer technology has also led to a rash of transmission defects, affecting millions of cars. This could make your vehicle a lemon under the federal warranty act or lemon law.  For More Information Please contact us @ (424) 449-0599

8L80E

When buying a used transmission, you should pay attention to the number of gears and torque capacity. These figures are often shown with the model number. The number of forward gears will be given with a letter T or L for transverse applications, while the torque capacity will be displayed with a number in the lower right corner. The 80 and 90 models have more gears and torque capacity than the thirty and forty rated transmissions, which means they are more powerful.

The GMC 8L80E used transmission is a six-speed automatic transmission with six forward gears and two overdrive ratios. This transmission is a significant technological advancement in the field of transmissions. Its innovative design displaced bands and over-running clutches that were used in previous automatic transmissions. In addition, the 6L80E placed a computer inside the oil pan.  For More Information Please contact us @ (424) 449-0599

10L90E

GMC's 10L90E used transmission is a great option for anyone looking to replace a worn or damaged transmission. The transmission is also available in a wide variety of models. The 10L90E is a 10-speed automatic transmission. It has an externally mounted transmission control unit (TCU) and a 260mm (10.2 inch) diameter torque converter. The transmission's torque capacity is about 460 lb-ft for the stock Tahoe, while the Chevrolet Performance 10L90E is rated at 715 lb-ft of torque. The 10L90E used transmission is compatible with both GM and GMC models, but only Gen V engines are compatible with this model. The transmission case is designed specifically for Gen V engines, which features a relocated bolt location for the top bellhousing.

The 10L90E transmission was developed in a joint venture between GM and Ford. The two companies decided to make a heavy-duty transmission to complement their lineups of vehicles. The Ford version was designed for rear-wheel-drive vehicles, while the GM version was intended for front-wheel-drive vehicles. It was later used in several 2017 models, including the GMC Suburban and the Cadillac Escalade. The 10L90E was also used in the SS ZL1 package for the Chevrolet Camaro.  For More Information Please contact us @ (424) 449-0599

6L80E

If you're looking for a GMC 6L80E used transmission, there are several options you may want to consider. For increased power and torque, you'll want to consider a higher-performance transmission. The 6L80E and 6L90E have solenoid-controlled clutch packs, meaning an electronic switch controls almost all of the functions of the transmission. This design has the benefit of being highly controllable, but it also increases the failure points.

When it comes to extending the life of your transmission, you may want to upgrade the torque converter clutch. These upgrades improve lockup and efficiency, which is essential in high-performance and heavy-duty vehicles. In addition to these improvements, you should consider changing the shift valve, which can be prone to seizure. This can lead to a code or other problem.   For More Information Please contact us @ (424) 449-0599

4L60

Whether you're looking to replace the transmission in your Chevy Tahoe, or need a used transmission for your GMC Yukon, there are several options to choose from. For example, you can use a Chevy NP231 transfer case. However, swapping parts may not be as straightforward as you may think.

The 4L60 is a three-piece cast aluminum case. It is about 21.9 inches long and features 30 splines on the input shaft. Depending on the application, it may have a different bellhousing design. Later models of this transmission have a squared-off adapter assembly. This transmission is primarily used in trucks and four-wheel-drive cars.  For More Information Please contact us @ (424) 449-0599
