I cannot thank Kosub Transmission enough. I recently had an intermittent rough shift issue in my 2024 GMC truck which was just past the OEM warranty. I started by taking it to a GM dealership. The dealership only offered to do a fluid flush and hope for the best. The dealer did the fluid flush and this did not fix the issue. I first called Kosub to see if they were willing to work on a newer, modern 10 speed transmission. There was no hesitation and they said to bring it on in. After the test drove the vehicle and performed diagnostics, Justin called with an update and a detailed plan. Within a few days, my truck was fixed. Justin‘s communication throughout this process is what stood out to me the most. While we were waiting for a part to be shipped, he called everyday with an update. Thank you Kosub family.

Very honest and polite staff. Went in expecting the worst and drove out with an inexpensive repair and a functioning truck. Turns out instead of a rebuild it was only filters, previous shop installed a knock off filter that was causing my issues. Gerald took the time to show me where the failure was on the filter and the reasoning as to why it was causing my shifting issues. This was my first time going to Kosub’s and they treated me like a life long customer. I cannot recommend them enough. If you’re looking for a honest shop please give them a call.

If you’re looking for transmission service, stop looking and bring your business to Kosub. Finding an honest and trustworthy shop is not easy anymore. This is the shop you can bring your diesel to and not have to worry. The help, attention, service, and education from Patrick and Justin are top notch. I appreciate you both for listening and then explaining the process, what you did, and what you found. You’ve got an easy and earned referral anytime I hear someone that needs transmission work and a lifelong customer the next time I need work or when I start my upgrades.
