This shop is bar none the best shop around. After my 2020 Sierra AT4 started shuttering and slipping at 126,000 miles, two other transmission shops told me I needed a new transmission. Both quotes were right around 9 grand. I brought it to New Fenton Holly Transmission and Gear. The owner recommended doing a fluid flush with anti slip fluid. I was a little skeptical at first but $689.00 vs $9,000.00 seemed like a no brainer. 50,000 miles later and my transmission is still going strong. No issues whatsoever. I just took it back to do another flush and fill to keep the fluid new and clean. The guys here are very friendly, they do great work, and are definitely looking out for the customer.
Thanks again, For a job well done.
