These guys are really helpful. They were too busy to do my job, but they were willing to help do everything else possible with the time they had. I definitely would have had them do the job if I had more time!

Transmission

At Ponci's Diesel Center in Fortuna, CA, we know that transmissions are witchcraft to most people. More often than not, if major damage has occurred, it’s a lot more time and cost effective to just replace the entire unit and get a fresh start. Here’s what to look out for, from Ponci's Diesel Center in Fortuna, CA.

quality car parked

If you drive a Mercedes, Porsche, Subaru, BMW, Jaguar, or other performance and luxury vehicle, you’re a person who appreciates the value of quality. At Ponci's Diesel Center, we share that appreciation - that’s why we specialize in quality cars and take pride in quality work.

Transmission

Automatic transmissions aren’t easily understood outside of specialists like those at Ponci's Diesel Center in Fortuna, CA. While it would be impossible to teach you enough to make you a transmission expert in a series of articles, what we can do is give you the fundamental knowledge you need to have a good idea of what your transmission is doing, and how it works.

Torque converter

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.

Engine Maintenance

Once your engine is installed, you’ll want to keep it running right. Ponci's Diesel Center in Fortuna, CA has you covered. Sometimes, engines just wear out - however, most of the time they meet an early demise as a result of improper maintenance. Keep your engine running like new by maintaining it the way your technician recommends.

battery warning light

It doesn't matter if you are driving a car or truck, jeep or SUV, a diesel 4x4 or a classic when those dash warning lights go off the first thing you do is think "how bad is it?" and "how much will it cost me?" followed quickly by "when was my last service visit?"!!  Driving your vehicle longer safely is all about getting it serviced based on what your vehicle manual recommends and these warning lights are alerting you to a situation that requires your attention. 

While not all warning lights are a sign that disaster is imminent, no warning indicator light should ever be ignored!
