Popular Transmission, Competent Repair

The 6L80/90 are popular units in many top-selling brand automobiles. Like all transmissions, these need routine services such as transmission fluid checks, changes, and flushes. In addition, we often make some common repairs. Our team is competent in taking care of them all. One notable issue is metal shavings inside the transmission. These can damage the internal components, and continuing to drive can lead to pump damage. Another source of trouble may be the transmission fluid. If there’s a lack of fluid or an inappropriate type, the unit may overheat. Also, some of these transmissions appear to be prone to cracking. If you notice slipping gears and inadequate torque, be sure to let us check your vehicle as soon as possible. Our professional mechanics will make the needed transmission repairs, returning you to the road quickly.

A Brief History & Our Approach

The 6L80/6L90 Transmission was introduced in 2007, marking a significant advancement in the automatic transmission market. It succeeded the 4L60/4L60E, which had been General Motors’ standard since the late '80s. The 6-speed transmission was notable for its integrated TCM (Transmission Control Module), also known as a TECHM, which is submerged in transmission fluid and combines the Transmission Control Module with all seven solenoids into one costly unit. Due to the complexity of these TECHMs, many shops nationwide hesitated to rebuild this transmission for years. Allstar Transmissions, however, was at the forefront of repairing these transmissions. We began servicing them in 2010, often for Police Cars and Municipality Vehicles that undergo rigorous use. We also provided support for dealerships with backordered units, ensuring these critical vehicles remained operational. Our extensive experience has led us to develop a foolproof method for repairing these transmissions effectively and durably. Our enhancements include numerous pressure adjustments, shift timing corrections, modifications to the transmission cooling system, and improvements in fuel mileage. As a result, our 6L80/6L90 Transmissions are among the most reliable and enduring nationwide.
