About Quantum Gear

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.

Almost too good to be true
Prior to completing my order, the order system requested all information pertinent to supplying the exact equipment for a turn key repair of my vehicle. The requested info allowed Quantum techs to pre program my transmission so that there was no need to go to a dealership for the service. Shipping was all prearranged. Fluids to fill the unit was included along with installation instructions. A simple email sets up the return freight for the core. A very pleasant experience start to finish.

Thank you so much, Gary! We're really glad the whole process went smoothly for you — getting the right fit for your vehicle and having everything prearranged is exactly what we aim for. We appreciate you taking the time to share your experience, and we're always here if you ever need anything!

I don’t do reviews
I don’t do reviews, but seriously I’m super happy with you guys, not one complaint, saved me probably about $4k, though I did the work myself (back yard mechanic)2012 gmc van, the transmission has been perfect, fluid is clean after probably 30k miles hasn’t lowered level at all. Shifts like butter. Thank you guys!
Response from Quantum GearAug 17, 2026
Jason, this made our day! Coming from someone who "doesn't do reviews," that means a lot. So glad your GMC van is shifting like butter and the fluid's still clean after 30k — that's exactly what a proper rebuild should do. Thanks for trusting us with it, and happy driving!
