Dartco Transmission

I had the misfortune of experiencing Allison transmission problems with my truck over the last month or so. It was shifting erratically and the Check engine light came on so I read the codes and tried two or three fixes suggested by a mechanic friend. Thought I fixed it til the light came back. Twice. My friend referred me to Dartco so I called them and was treated so well I took it in. Michael (I think he’s The Mgr, and if he isn’t he should be) couldn’t have been more helpful. He and one of their techs plugged my truck into their laptop and we drove around a bit. The tech determined that a speed sensor was bad so they plugged one in and now it’s shifting and running like it should. These two pros helped me for over an hour with the most professionalism I’ve seen in far too long. The sign on their wall reads «We Sell Service» and I received just that. I’ve heard from two friends recently about problems with their Allison Transmissions at low mileage so I think it must be a common problem for many people. If you’re one of them take it to Dartco in Anaheim, they’re The Best! Thanks again Mike!!!
