Since the early 1900s, Mack Trucks have been one of the best brands running. This American classic can be seen everywhere from big cities to the smallest towns. Tonka has even celebrated the Mack name with their own line of children's toys. These trucks are big and powerful, and unfortunately, if they break down, they're awfully difficult to shop for. Ordering a new engine or transmission for your Mack truck could end up being really expensive. To save some money, a lot of people get their Mack parts used. But the problem with used parts is that you don't know who to trust. Some companies will sell you a used Mack engine for a hefty price, and it will inevitably break down in months.
