​​From the very beginning in 2001 the Duramax engine has proved to be not only pull anything you put behind it, but to also be a great use for daily driving and comfort. At Neal's Repair Service we have years of experience with these engines along with the Allison transmissions. ​​We see all the common problems and have implemented practices and procedures to ensure longevity out of your vehicle. NRS also offers a full line of performance options to optimize performance and fuel mileage from the Duramax engines. Don't waste your time and money with mechanics who have no experience with these vehicles and want to "try" parts. Spend a few minutes with our staff and you will see the true difference between our services and others sacrifices.
