I know of a customer running a fleet of over 50 c500s 24/7 and won't trade them in, (Clark [within the last 2 years] made them an offer I could not have refused) and while I can not say the name of the company I bet over 1/2 of the people reading this forum have some of their products in your shop. They took the inching control off this truck when they got them, so have never had the trans oil contaminated by brake fluid.
