Transmissions are complicated and intricate pieces of equipment. Many general mechanic shops won’t touch a transmission, if it’s anything more than simply installing a new one. Transmissions are one aspect of a vehicle that even experienced mechanics often don’t dare delve into, and is easily the most mysterious and misunderstood system in the automotive world. You need a shop that you can trust to perform the best work on whatever your transmission may be in need of.

If you drive a lightweight car, truck, or SUV, the torque converter you have installed is probably just fine. For those of you with more heavy-duty applications, like high horsepower setups or towing rigs, the stock converter may not be enough. At Ponci's Diesel Center in Fortuna, CA, we can help with that.

When driving around town, your vehicle's engine needs clean air to burn the fuel – and it needs a lot. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas. All that air passes through a filter that catches the dust and dirt. Eventually, the filter gets completely full, and because the filter can only hold so much, dirt starts getting through. At Ponci's Diesel Center in Fortuna, we want to help you get the best air quality in your vehicle, but first, we want to explain the process of where this dirty air is going.
