My nephew took his truck here after being in three other shops not being able to find the problem with his 6.0 and his oil leak. After one week Dakota was able to help navigate the issue and he was on the road days later. Just like anybody else short on staff time was an issue, but all in all I’m glad we waited and got the job done right! I would’ve waited two more weeks just to know the issue was fixed.Services: Transmission

Had all my fluids and filters changed in our Class A RV. When we got to Kerrvile the Jeep intow was covered with oil.I slid underneither and found the Oil and Transmission filter with areas around them cover in fluid. Both filters were do tight I could barely get them loose. Made them hand tight and when we got to Carlsbad all was good.

Thought with all the good reviews, this would be a good place to take my truck for some basic maintenance and troubleshooting. Tried to make an appointment for them to look at it. They said drop it off on Monday and we'll get it in early in the week. Great done deal. However a week went by so I called to check up. They had no clue and told me they would call back after they spoke with a tech. "I" called back shortly before 5:00 and it was as if they never knew the truck was there or that I called earlier. Waited another week and called back figuring they are pretty busy. Again it was if they had no clue. They said they would call back. Big surprise... they never did. I called again Friday evening and left a message of my unsatisfactory customer service. Finally I went in the following Monday afternoon and they had no clue still. Told them I was just going to pick up my truck at this point and move on. The receptionist told me that she was going to get her dad to talk to me. Three minutes later she said he went to go test drive a red car. Didn't need to talk to him anyway. Come to find out my wife spotted a guy leaving (peeled out) as I was in the office right before I came out. In summary, this place is extremely unprofessional and doesn't deserve people's hard earned money.

Sean really knows diesels! Took my motorhome to him with a check engine light. He quickly diagnosed the problem and repaired it for a very good price. I will be bringing all my diesel work to Tomball Diesel!Service: Engine repair

Been here several times to get glow plugs, injectors, belt and tensioner work done. They always get the job done and the prices are fair. Most times repairs are done same day or the next morning.

Great service, Sean the owner is on the ball to get you back on the road. Will help out with vendor warranty problems when he can.

Very friendly and helpful staff. They seemed more concerned with helping me and my truck to pass inspection than they did selling me on something I didn’t need. Highly recommended and I will be back for my maintenance needs!
