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.

Transmission replacement
To start off with, i am a person that likes to talk to a person when dealing with parts, especially when working with major parts, Like transmissions. Quantum made this effortless, just gave them the year, VIN, and they handled everything from there. From ordering to core return, was simple as could be. Was easy, and simple, and would do it again.
Response from Quantum GearSep 6, 2026
That means a lot, Michael. A transmission is not something you want to order blind, so being able to talk it through and just hand us the year and VIN is exactly how we like to do it. Glad the core return was painless too.

I highly recommend this company
I highly recommend this company for transmissions. We installed one in my 2015 Chevy Silverado 1500 LT Z71 with the help of my dad‘s nephew after installing, took it on a test run within 5 to 10 miles of test driving the transmission was dialed in tight shifting correctly and running better than ever.
Response from Quantum GearSep 6, 2026
Running better than ever after a 5 to 10 mile shakedown is a great sign, Edward. Glad the install went smooth with your dad's nephew. Thanks for the recommendation!

The transmission was rebuilt new as expected and arrived timely. The only down side is the billing process. Once you order your locked in and then the second bill comes for shipping and core charge. It would be nice if this process was more transparent up front. Just tell people what the all in cost is!
Response from Quantum GearSep 6, 2026
Thank you for the honest feedback, Jeff, and glad the unit was right and arrived on time. You are right about the billing, that is how our older system worked. We have since automated it, so the full cost including shipping and the core charge is calculated and shown at checkout up front. No more second bill. Appreciate you pointing it out.

The whole process was smooth
The whole process was smooth. Received my transmission a week after ordering, and called for pickup of my core within 4 days. Pickup was just as smooth, and I've already received the core return. Highly recommend!
Response from Quantum GearSep 6, 2026
A week to your door and the core refund already back in your hands, that is how it should run every time. Thanks Amanda, appreciate the recommendation.

Quantum Gear was easy to work with the whole way through. The pricing was as good or better than any other rebuilt options available, and they program the transmission before shipping so my car (2013 GMC Yukon XL) started up and drove great right after the installation. They handled the delivery and core return without any issues. Good company to work with.
Response from Quantum GearSep 6, 2026
Thank you Jonathan! Glad the pricing worked out and that the Yukon XL fired up and drove great right after the install. Delivery and the core return going without a hitch is what we aim for every time. Good working with you too.
