Review us on:



Shawn was a huge help on getting our vehicle running right! There was a lot of work that needed to be done and he was great at calling & keeping us updated. He is also very respectful and professional! Our vehicle is now running like it’s brand new and it was all done at a great reasonable price! Highly recommend Professional Auto Engines!

I called with starter problems, Shawn sent the wrecker out immediately! Offered a free 60 point inspection and did an amazing job communicating on all the issues his crew was able to find. Got my truck back and the difference in performance is incredible. Won't be taking another vehicle anywhere but here from now on...THANK YOU!!

-Jay V.

Definitely was a great experience with this repair shot! They were fair in their prices and did a awesome job on my Jeep! They even made sure to call and see how it was running a week or so afterwards! I’ve been spreading the word about them! Thank you Shawn for taking GREAT care of us!

Shawn made sure my truck was completely road ready when I was in a real bind for time. My limited time frame was met and the work exceeded my expectations. When I need some work done and I'm nearby, I will definitely be back. Not to mention, if I need some major done, I will be doing my best to get it done here. Can't recommend them enough.

A disabled mechanic myself it is hard to find a knowledgeable and honest shop. Shawn actually diagnosed the problem with parts and labor just over $1200. A very fair price consideting the dealership could not pinpoint the issue and wanted to replace $4000 in parts "to fix the truck". I will definitely use Professional Auto and Engine for any future work needed. #Duramax #Diesel life

I'm Very satisfied. My AC wasn't working because of electrical issues and my car was running pretty rough. I used the night drop off the next morning I was contacted with the services they wanted to provide for me and I gave them the go ahead. The following day I got my car back cold AC and it drove like a brand new car I highly recommend professional auto engines of Slidell.

-Chris S.

Stopping through New Orleans on my way to Fla. my maintenance light goes off...the guy at pro auto let me know they were slammed as I was on a long road trip & needed quick service. He was gracious enough to take a look under my hood & suggest a more rapid solution, point me in the right direction free of charge !!

-Kashi B.

I am from out of town, and my a/c was broken. These folks promised and delivered great service for a reasonable price. If I didn't live 3 hours away, I would bring my car to them for everything!

I was traveling from Baton Rouge to Alabama when my car started running hot. I Took my car to them they found out what the problem was ordered the part and put it on and I am totally satisfied with my first time experience.

-LDE JR

I took my Mom's 06 Honda Accord or a check up. It has 86,000 miles and original starter, alternator, etc... Shawn was completely honest and found nothing wrong with the car. I refer people to him with no worries.

-Norman Slade

Mr. Shawn is a very professional mechanic who knows what he is doing! He took my truck in, diagnosed it and finished it all in the same day. My truck runs very smoothly and it’s backed up by a 36,000 mile warranty. I would recommend him

-Henry J Calamari

I previously went to a mechanic shop and was told my AC compressor (an expensive part) was bad. I went to professional auto engines and I was told it was actually only an inexpensive part that was wrong. It was fixed instantly and saved me hundreds of dollars. If you want honesty, great service and low prices this is a great place for your vehicle needs. All around great people and great service!!

-Kelsey Dauzat

The owner Shawn was very friendly and helpful in resolving my air conditioning issue. Fair pricing and good work with a quick turn around. I would highly recommend this shop for your automotive needs.

-Mike Treadway

Highly recommended , I brought the truck in on a Friday with a blown engine. Shawn was on top with finding and replacing and I was able to pick up the truck on Thursday. Very easy and quick to work with. No throw in charges, they call when the motor is out and advises you of what parts is no more good and will advise of older parts that should be changed while the engine is being replaced.Only charge for parts and no labor. Great service!

-Karen Imbraguglio

Truck broke down on I-12 on my way home to Houston from Florida. Called Shawn who coordinated tow to shop. Had a fuel line issue diagnosed and replaced in quick-time and got me back on the road home. Great job, great service! Thank you!!!

-Bill Winney

We were traveling from Saint Augustine, Florida to Houston, Texas pulling a 28ft RV. Our check engine light came on and Pro-Auto were the first people we called who told us they could work on our disel. We were in a huge rush as we are traveling half way across the country to adopt a baby. Pro-Auto helped us immediately and we were back on the road in no time! Thank you so much Pro-Auto for treating us like family!

-Sarah Ann Fahed

Sean and his crew did a great job on our Subaru. The work was done in a timely, manner and we knew upfront what we needed repaired. It was a welcome relief on price and repair time. Thanks again Sean. Calvin and Nga
