I can't say enough about ABM transmission /Mack's diesel. I have brought 08 duramax several times to them for various repairs and very happy with service and knowledge of vehicles. They have that old school feel with the twist of modern technology. I am very picky with my truck and who works on it besides myself , I don't trust anyone else to work on my truck but them. They r very personable easy to talk to. I am a customer for life !!!!

Literally the best place to get your car done no hassle, no gimmicks, no shady business. Will definitely be going back 100% for life

Mark and Eric fixed a fuel delivery problem on my diesel motorhome that the largest truck repair shop in Springfield couldn't resolve. And they fixed it at exactly the quoted price. I can't say enough about their commitment to get the job done right and honesty in our dealings. They've earned my business for any repair and maintenance work on this unit I need in the future.

I have had numerous problems in the past with mis-diagnosed issues and lingering problems at other businesses. Mark at ABM and more exclusively, Mack's Diesel has been phenomenal. The real deal autorepair shop. I have brought my repairs and issues to Mark and his team at ABM multiple times, all great experiences. I was in a front end accident that was improperly assessed by another company, Mark corrected all of their mistakes at a fair and concise price point. He and his team will call you ASAP, and review your best options for repair/work to be completed. He is a polite, timely business owner, with the customer's best interests, and personal time in mind. Reasonable prices, generous person. Overall great experience, will bring all my dreaded dash-light issues, and other problems to him and his business, without blinking an eye.

Mark provided me with accurate diagnostics and realistic pricing. It has been over a year since my motor swap and the car runs beautifully. I recommend everyone who asks about car repairs to him.
