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.

need to review your transportation rules
Service was good except for your insistence that my address was residential, not commercial, and the added $60 that incurred. Transmission worked as advertised. Early days to provide feedback on performance.
Response from Quantum GearAug 19, 2026
Thanks for the honest feedback, and glad the transmission worked as advertised! On the shipping side — freight carriers classify addresses using a national address database, and unfortunately yours is listed as residential there, which is where that surcharge occasionally comes from. It's out of our hands on that one, but we always try to keep things upfront. Really appreciate your business!

Very happy with the product and was…
Very happy with the product and was shipped promptly. My only critique would be if the transmission had been placed closer to my shop, because I had to get it placed into the back of my pickup for transport to another location. Otherwise, I feel I received a good deal price wise and received my core money back. Thank you
Response from Quantum GearAug 19, 2026
Really appreciate the kind words on the product and pricing, and glad the core refund went smoothly! On the delivery — you're right, and we're sorry it didn't get closer to your shop. Freight delivery can sometimes come down to the carrier and even the individual driver on the route, so it's not always as smooth as we'd like. If you order again, feel free to reach out to us before it ships and we'll do our best to help coordinate the drop-off to make it easier. Thanks for the feedback, and for your business!

If you need a transmission, don’t hesitate, go quantum gear!
⭐⭐⭐⭐⭐ I highly recommend Quantum Gear! I ordered a transmission from them with very little knowledge about who they were or how the process worked, so I honestly wasn’t sure what to expect. I couldn’t have been more pleased with how smoothly everything went. We received a great transmission, and I was especially impressed that it came with all the necessary fluids and was already programmed. That meant we didn’t have to take it to a dealership afterward just to have it programmed, which made the whole process so much easier. From start to finish, everything went smoothly, and the quality and convenience were outstanding. Highly, highly recommend Quantum Gear! I would absolutely order from them again if I ever need another transmission. I would also like to say the delivery service was great. They use ESTES and at first I didn’t think we would know the step-by-step moves on when it was going to get there, but once it started rolling with the carrier, it was seamless. Thank you, Quantum Gear, for making the entire experience so easy! ⭐⭐⭐⭐⭐
Response from Quantum GearAug 18, 2026
Adina, thank you so much for such a thoughtful review! Coming in without knowing much and having it all go this smoothly is exactly the experience we want to give people. Glad it showed up ready with everything you needed, and that the ESTES delivery worked out well too. We'd be honored to help again if you ever need another one. Thank you!
