In the latest video from the Transtar Garage Studio, Dave Hritsko, Transtar’s technical parts specialist, talks about the Ford 5R110W pump.

This pump, Hritsko says, may have been surpassed by newer equipment, but there are still a lot of trucks out there with it. The pairing of this pump with the engine, Hritsko says in the video, is a happy marriage “until a divorce happens.” What does that mean? “When a transmission gets burned up or has an issue and you have to remove it from the engine.”

So what are the issues that arise with this pump, and what can you do to resolve these issues? The video above has your answers.
