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.

Sobre Quantum Gear
Escrito por la empresa
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.

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.

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!

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

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!

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.

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.

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.

Would highly recommend this company
I talked to an individual there to figure out exactly what I needed gave them my information like vin# and what I was wanting out of my new transmission I went with the upgraded transmission for I don't remember a couple hundred more. It arrived at my house on time and beautifully packaged it was preprogrammed so I didn't have to worry about getting it to a shop or buying expensive programming tools like another company I checked into first. I did a road trip after I installed it and did the 500 mile break in which I will say felt weird the computer has to go through a programming process and sometimes it just felt weird but that was 7000 miles ago I have pulled my 3500lb boat through the mountains here in Arkansas numerous times and made a few road trips I am very happy with the product and the company would recommend them

Respuesta de Quantum Gear
Man, appreciate you writing all that out, Jeff. Pulling a 3,500lb boat through the mountains in Arkansas at 7,000 miles is exactly what these are built to do. Really glad we could get you dialed in from the VIN and that it showed up on time. Thanks for recommending us!
AMAZING COMPANY TO WORK WITH
