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. Donald Collins

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.

⭐⭐⭐⭐⭐
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! ⭐⭐⭐⭐⭐

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!

Great communication
Great communication, Transmission (6l80e) works great. Only complaint is that the shipping charge was $650, when it was estimated at $450.
13 augustus 2026
Antwoord van Quantum Gear
Thank you for the kind words on the communication, and glad the 6L80e is running great! You're absolutely right about the shipping, and we apologize for the difference. Previously our system calculated the exact freight after the order was placed, which is what caused the gap between the estimate and the final $650. We've since updated and reconfigured that system, so customers now see the exact shipping cost up front — no more surprises. We really appreciate your patience and your feedback; it genuinely helped.
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.

They were very responsive to questions before the purchase. All communication was very clear amd punctual. Shipping was quick. Trans actually shipped the day it was ordered. It was packaged very well. It included everything but the tools. Install was straight forward. Had instructions on how to program the shift module all without needing any computers of any sort. Gm 6L80 trans in a 2017 suburban. Put around 3000 miles on it so far and it drives better then it ever has for me. Would not hesitate to do business with them again
