Another happy customer:
"I went to 3A transmission and Diesel to see if they could fix my abs and hill assent lights on. Edgar the manager said he doesn’t work on F53 RV, but he would take a look, and he was able to fix the sensors and pack the wheel bearings, and get my air conditioner cold. I highly recommend this awesome business. Everyone is so nice starting from Marisol their front line receptionist, all the workers there and of course Edgar. Thank you so much."

A lot of diesel owners grew up hearing that long idling is “good for the engine.”
In reality, excessive idling can contribute to carbon buildup, unnecessary fuel consumption, and additional wear, especially in modern diesel systems.
Proper warm-up is important, but long idle times usually provide little benefit once the engine is ready to drive.
Understanding how modern diesel systems operate helps protect long-term performance. 🚛

Your brakes are one of your vehicle’s most important safety systems, so warning signs should never be ignored. Squealing, grinding, vibrations, pulling, or a brake pedal that feels different can indicate that your braking system needs attention. 3A Automotive & Diesel offers brake inspections, pad and rotor replacement, caliper service, and brake flushes to help keep your vehicle stopping safely.

🚨 The cheapest brake job can become the most expensive one.
Choosing the lowest price might save you money today, but low-quality parts can wear faster, create more noise, or simply not perform the way your vehicle needs them to.
When it comes to brakes, the goal isn't just to spend less. It's to get the right parts, proper installation, and reliable stopping power.
Your brakes are one place where quality matters. 🔧
