Over Quantum Gear
Geschreven door het bedrijf
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.

Pre flashed made it easy
Shipping was fast and simple with the core return being just as simple. Transmission was in good shape and seems to be working great. Really liked the fact that t was flashed already and as easy as plug and play.

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.

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.

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!

Antwoord van Quantum Gear
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.
Shipping and all that was great
Shipping and all that was great, but my transmission still down shifts pretty hard, I’ve put 15k miles on the replaced 6l80

Antwoord van Quantum Gear
Thanks for the kind words on the shipping, Bodie. On the hard downshifts, your transmission is under warranty, so no need to worry there. Our manager has already reached out to you, please check your email so we can help get this sorted. It matters to us that you end up happy with the unit.

Thank you Kaitlyn! Delivery, communication and the product itself, that is the whole job. Appreciate you taking a minute to say so.
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!

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.

Antwoord van Quantum Gear
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.

Sorry about the fluids missing on that shipment, Tony, that one is on us. Glad we could get you taken care of quickly on the reimbursement. Appreciate you still giving us a shout out, and we will be here next time.
Worth the money
I bought a 6L80 around a year ago and it runs perfectly, I have had no problems with the transmission and would 100% buy another one from here for the price they were offering.

A year in and still running perfectly, that is exactly what we like to hear Eduardo. Thanks a lot, and we will be here when you need another one.

Three months and 2,500 miles with no complaints, good to hear Michael. Thanks for circling back with an update.
My 6L90E tranny
The delivery company was awesome, drop off and core pick up was great. My 6L90E transmission pulls strong and runs real smooth. I recommend using Quantum Gear to anyone needing a good transmission. I would definitely use them again and will. Next will be my 4L60E in my 1/2 ton chevy.

Love hearing the 6L90E pulls strong and runs smooth. And we will be ready when it is time for the 4L60E in the half ton. Thanks a lot!

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.
