The whole process was great with the exception of one thing. Once the transmission had been installed, we had to get the codes reset. Has been running with no issues since. Donald Collins

À propos de Quantum Gear
Écrit par l'entreprise
At Quantum Gear, we understand that a failing transmission is stressful — and that trusting someone with a repair this important isn't an easy decision. That's why we focus on doing things the right way, from the first click to the day your unit arrives.
We specialize in remanufactured GM automatic transmissions, with our core lineup built around the 6L80 and 6L90. Every unit goes through a complete remanufacturing process, where worn and failure-prone components are replaced and restored. Before anything ships, each transmission is tested on a dynamometer, so we know it performs the way it should — not just on paper, but under real load.
We ship nationwide. Ordering is done online, and your unit is delivered by freight straight to you, wherever you are in the country.
Whether you're a repair shop, a mechanic, or a driver simply trying to get your vehicle back on the road, our goal is the same: make the process clear and straightforward, and hand you a unit you can rely on. No guesswork, no runaround — just a properly remanufactured transmission and people who are ready to help when you have questions.

Transmission is operating perfectly.
Overall, a very good experience, the transmission is operating quite nicely, only minor issue, i was shorted about 3 quarts of trans. fluid, but honestly no complaints.
