About Our Remanufactured 6L90 Transmission
At Reman-Transmission we understand that replacing your 6L90 transmission can be a confusing mess. You may be wondering if you should go with a rebuilt 6L90 transmission, a used 6L90 transmission, or a new crate 6L90 transmission replacement. If you are looking for a quality and affordability in your replacement, consider going with a remanufactured 6L90 transmission, as this option is quickly rising to be the top choice in the industry.
If you find that you need a new 6L90 transmission, it is important to trust a trained professional who can maximize the performance of your transmission which is where a transmission that is compatible with your vehicle’s powertrain is critical. With a remanufactured 6L90 transmission, all components are tested to ensure they meet or exceed the specifications of the manufacturer. If a part is faulty, a swap occurs, and it is replaced with new ones as well, optimizing the condition of your transmission. Then, they are tested to make sure that they meet the specification of the original equipment manufacturer (OEM). Beyond that, each and every component is replaced with new or rebuilt parts and all of the possible defects from the factory will be amended, thus giving you a 6L90 transmission that will actually go the distance.
If you look at the prices of our remanufactured 6L90 transmissions and need something a little cheaper, we carry a full selection of quality used 6L90 transmissions in our online catalog. Using our unique VIN search system, we can help you find the right transmission for an American or import car at the best price possible.
At Reman-Transmission, we are here to help you if you are looking for a “6L90 transmission near me”.

6L90 Transmission Remanufacturing Process
Our 6L90 Transmission Upgrades
Fluid pump is fully detailed with resurfaced pump rotor mating surfaces and machined pump body mating surfaces to maintain correct fluid pressures.
Late style stator support shaft with updated seal rings used exclusively in all units to eliminate seal leakage.
Upgraded 38-element low sprag installed in all units to increase holding capacity.
All-new custom-spec bushings to improve internal fluid flow control and pressures.
Fully remanufactured torque converter is tested for leaks, lockup, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibility of front seal leaks, premature bushing wear, and vibration.
Boost sleeves and planetary covers are replaced.
Updated drums are used to prevent cracking at the welds.
Bushings and machined surfaces polished to a mirror-like OE finish of 15 RA or less.
Tru-Flat qualification process applied to transmission case, valve body, pump, and channel plate prevent cross leaks and pressure losses.
Every transmission is cold-and hot-tested using a proprietary dynamometer testing program that includes fully synthetic automatic transmission fluid and a filtration system.
6L90 Frequently Asked Questions
Is the 6L90 a good transmission?
Yes, the 6L90 transmission is a good transmission but every transmission has issues from time to time. If you want a quality transmission, go with a remanufactured 6L90 transmission. A remanufactured transmission has had all parts replaced with new or rebuilt parts set to factory specs along with any factory defects amended.
How much HP can a 6L90E handle?
The 6L90E can handle up to 700 hp in its stock application from the factory. Our remanufactured 6L90 is rebuilt to factory specifications so it will be able to handle the same or more since it also has factory defects fixed from the start.
What is the difference between a 6L80 and a 6L90?
The 6L90 transmission is a heavy-duty version of the 6L80E automatic. The 6L90 transmission also has a strengthened input gear set. It also has two additional pinion gears, giving it six in total. The 6L90 transmission has won more clutch plates in each clutch, when compared to the 6L80-E.
How do I identify a 6L90 transmission?
If you are looking for a way to identify your transmission, you should take a look at the 4-digit designation on the transmission tag. The first digit usually designates the model year and the 2nd digit designates the transmission. B is a 6L50, C is a 6L80, and D is a 6L90. Look for the D to identify your transmission.
6L90 History & Information
Produced by General Motors (GM), the 6L90 transmission is known to be a workhorse of a transmission that is commonly found in light-duty and medium-duty truck applications. Prior to the development of the 6L90, GM produced a number of good predecessors leading up to it that became the basis of what the 6L90 would be. Prior to the 6L90 transmission, GM and Turbo-Hydramatic put into production the 4L60E, 4L65E, 4L70E, 4L80E, and 4L85E transmissions. Those series of transmissions were all inspired by the famous Turbo-Hydramatic 700R4 transmission. The 4-speed 4L60 and beyond series Turbo-Hydramatic transmissions were so groundbreaking when they came out in 1982 that they remained in production throughout GM’s lineup for nearly 3 decades, however; General Motors soon decided it was time to introduce a new 6-speed transmission that would ultimately replace its predecessors to keep up with the fastly innovating automotive industry.
The 6L80, which was the 6L90’s older brother, was first introduced in 2005 and remains popular in numerous models today. General Motors (GM) used the 6L90 transmission in numerous domestic auto manufacturers like Chevrolet, GMC, and Cadillac. including the Cadillac CTS-V, GMC Yukon, Chevrolet Suburban, GMC Savana, GMC Sierra, Express Van, and Chevrolet Silverado. Found today in American and import cars, the transmission is able to shift flawlessly, making it a great option for numerous vehicle classes, including several truck brands. For the 4x4 applications of the 6L90 transmission, it was primarily mated with an MP3024HD or MP1226XHD transfer case. Regardless, always check your VIN to make sure.
Regarding the technical information, there are 3 gear sets for the 6L90 transmission. There is a simple input planetary gear set and two output gear sets. One output gearset is a compound gearset that comes with three pairs of pinion gears. The 6L90 transmission also comes with an advanced transmission control system (TCS) which allows the modules to sit reliably inside the transmission itself. Because the module and transmission are assembled with each other, the 6L90 transmission is relatively easy to take apart and put together. Finally, there is also a performance algorithm shifting and braking feature available on many 6L90 transmissions. This monitors how the driver upshifts or downshifts, adjusting the engine output accordingly.
