Customer came in worried his truck was headed for transmission problems after it went into limp mode.

After diagnosis, we found the fuel filter was way past due for replacement & restricting fuel flow. While it’s in the shop, we’re also taking care of some maintenance items to keep this truck running strong:👏🏼

✔️ New fuel filter
✔️ New air filter
✔️ Fresh oil change
✔️ Transmission filter & fluid service

Regular maintenance saves big repairs. Don’t wait until your truck leaves you stranded!

Quick reminder: air filters aren’t lifetime memberships.😐

When an air filter gets packed full of dirt, dust, bugs, & debris like this, your engine has to work harder to pull in clean air.

A clean air filter helps your truck breathe easier, run smoother, & stay protected for the long haul. Simple maintenance now can save big repairs later. 💁🏼‍♀️

Preventative maintenance goes a long way when it comes to keeping your diesel on the road & out of the shop for major repairs. This 2017 Ram 3500 came in for a full maintenance service including new fuel filters, fresh oil change, a brake flush, air filters, & front brake pads. 🔥

Brake flushes are important & are commonly overlooked. Over time, brake fluid absorbs moisture which can lead to corrosion, soft brake pedal feel, & premature brake component failure. Fresh fluid helps protect the braking system & keeps stopping power where it needs to be.

Staying on top of routine maintenance like this helps extend the life of the truck, improves reliability, & can save thousands by preventing bigger issues down the road.👏🏼

At Grayson County Diesel, our customers come first & our techs stay on top of their game to make sure your truck is getting the attention it deserves. Come see us or give us a call!📞

🛠️ Full service day here at Grayson County Diesel LLC!
This Ford Super Duty came in needing some serious attention and we’re giving it exactly that. Here’s what we’ve got going on:
🔩 Upper oil pan & front cover resealed — both were leaking. You can see the parts getting cleaned up in the washer before everything goes back together the RIGHT way.
💨 Crankcase reroute being installed — excess crankcase pressure is one of the biggest causes of repeat leaks on these engines. We’re fixing the root cause, not just the symptom.
🚛 Rotted cab mounts replaced — out with the junk, in with solid mounts. Safety and ride quality matter.
🏋️ Leveling bags going on the rear — this customer tows hard and their truck needs to be ready for it. No more squatting under load.
We don’t do band-aid fixes. We do it right the first time. 💪
