Lonestar Transmissions in
Rockwall (TX)

DONT BELIEVE THE RATING! they’re not a good mechanic shop! They charge you for towing and diagnosis. A complete opposite to what they have posted on their doors! If their mechanics arent there they make you leave your car there and charge you for leaving it there. If you want to save money go to another shop. This place isnt it. Easily 0 stars.

If I could rate zero I would. Worst communication I have ever received from a place of business. Took my car in for a quote on a transmission. Took over one week. When I declined my service it took 3 days to get my vehicle back. Was charged for a battery that I did not agree to purchase and never even received a receipt for the item I purchased. Gave my credit card information to the owner. He wrote it down and took two days to charge me, which means my card info must of been laying around for who knows to see it. I am sure the company must do good work but overall I did not receive any proper communication and got terrible customer service.

My son took his truck here to have a Flowmaster put on. Fast service and a very reasonable price. The truck sounds great! I will definitely be returning here for all my vehicle repairs. Thanks Sparky!

Replaced my Trans on my 2007 F-150 3 years ago and is still running like a top. Excellent service, quality repair, and best prices all around.

Honest guys! Toyota wanted over $4000 to replace my transmission after running a full diagnostic. Lonestar said it needed a simple repair and I appreciate their honesty. UPDATE - 10/30/23 We just traded the Toyota Tacoma mentioned above. The transmission was still perfect after 240,000 miles. No problems with the repair in 8 years and 130,000 additional miles

We have had two transmissions replaced with these guys and numerous other repairs. They are honest and do quality work at great prices! I had been taking to dealer or other shops. They found things the other shop had broken. One shop located near Lavon had placed antifreeze instead of windshield wiper fluid in my vehicle during oil change apparently. Another shop in Lavon charged us over 400 for a battery replacement. We are so thankful we found Sparky.

They kept my car for 3 weeks and did nothing to it at all. My battery was dead when I went to get it back. They charged me $100 to tell me it needed a new transmission for$5,350.00. but it doesn't. It only needed more fluid. Sad that they could charge me for nothing

We have used Lonestar Transmissions for repairs for many years and have always been happy with the results. They always fix what needs to be fixed and don't try to get us to do more than needs to be done. The repairs were done right and stayed fixed. But for any adjustments that needed to be made, they were more than happy to make them. I have recently learned that they are now doing general repairs in addition to transmissions.

The owner "Sparky" stood by our side as we dealt with the problems with our warranty company. After everything was approved he completed the repairs in a timely manner. I plan to bring my van to his shop for an accesment. Thank you "Sparky for everything!

Everyone at Lone Star was awesome and very knowledgeable. They even went as far as to personally drive out to Paris TX to get eyes on a 350 transmission for my vehicle before buying. Sparky and the guys are pros, will definitely do business with them again!

Had my rear end replaced & paid in cash. I counted my cash twice, paid Sparky & left. Got a call about an hour later that I gave him an extra $100 by mistake and to come get it. Other than the fantastic work they’ve done on my truck, they’re honest. I would have never known I over paid, and he could have easily said nothing. Most places would have taken the extra money. Not Sparky.

I have to say Sparky and his crew were up front honest and down to earth people. Sparky told me the price and stuck to it with so many options out there, so glad I choose them. Will def bring all future vehicles there for the quick turn around and honest pricing!!

Sparky is a very knowledgeable man! A man with a kind and caring heart. He does a great job with honest pricing. Truly a man of Integrity! I would recommend him to anyone needing transmission work!

Sparky is one of the most honest mechanics I’ve ever met. He straight forward and truthful. He helped me resolve issues with my RV transmission. I highly recommend Sparky and this shop. Thanks Sparky!!! I really appreciate you.

So the people are nice and Sparky is the one I dealt with the most, he was always nice. The shop worked with me a lot to keep the price down as a struggling mom. I went in a slipping transmission and they replaced my computer, had to program it, a solenoid assembly, 10 hours of repair time. They had my vehicle for about a month. Car was great after the second time I picked it up after a sensor they thought was the issue ended up not being it, but was about a week later and my car started slipping once again. It DID stop after a few days though so I didn’t take it back. It’s been about two weeks now and my transmission is back to slipping every time I press the gas. Also is taking a car a very long time to accelerate. Sparky told me my car was very tricky and in the 50+ years he’s been working on cars he was very stumped on mine. I’m hoping my car can keep going and not leave me stranded until I can afford it and take it somewhere to be fixed.

I took my jeep to this transmission shop, on March 1, 2021 to have my transmission evaluated because the check engine light came on, showing gear one, incorrect ratio. Sparky told me he would scan the transmission and there would be no charge, I informed him that I had car shield auto Warranty. He then said he would notify them. They came (the car shield adjuster) came on March 4, 2021 and he evaluated the transmission and said he would get back with us in 48 hours. On March 8, 2021, the adjuster notified me that the car shield policy had been cancelled due to modification to the jeep. When I heard that, I called sparky, and told him that I needed to come pick up my jeep which was on the 8th. Sparky told me that I could not pick up my jeep until that Friday which was March 12, due to the fact that he pulled my transmission out of the jeep and that he had a tech out and said that he was not sure when I could pick it up. On Tuesday on March 13th, I showed up at his shop, and I spoke with the tech, and the tech said that the transmission was never pulled out of my jeep. Then sparky told me that I had to pay $516 in order take my jeep which included conversations with car shield and he drained my transmission fluid without my permission OR car shield's permission. When I pick up my jeep on Wednesday, on the receipt, he wrote; "it was not electrical, that I needed a new transmission because it had a bad lubricated internal part" I had to pay the money to get my jeep out. I took my jeep to another transmission shop, and found out that it was electrical and NOT an internal part. So Sparky lied to me, and was going to charge me $3,400 for a transmission that I did NOT need. All I had to replace was the cylonoids which was electrical. Now my jeep runs great. Beware of taking your jeep to this transmission shop. He misdiagnosed my jeep trying to get more money out of me for something that didn't need to be done!

Short version: Everyone hates taking vehicles in for repairs. You never know what you're going to get. But after trying Lonestar (and dealing with Mr. Sparky)... I have found my new trans shop for sure. Per above, I gave them 5-stars. Longer version: I took my F-150 to the Ford dealership, and told them the transmission pan was dripping. They looked and said "yep, and you have a leaking electrical connector as well... that'll be $1,800.00." That price seemed completely crazy to me so I checked reviews and found Lonestar Transmission. I told them what was up and they said "yep, happens all the time on the F-150's. We'll fix it all for $480.00." I picked up the truck from Ford and drove it directly Lonestar. The next day they called me and and it was ready to be picked up. I was thrilled. Also, I'm not much of a people person, so when someone says something like "talk to Sparky, he's great," that doesn't appeal to me. That being said, Sparky really was a super nice dude, and did make me feel like we were old friends after about 30 seconds of talking. Oddly enough, I now join the group that says "go talk to Sparky" haha. Anyway, they saved me a ton of money, and I am a very happy customer. Definitely worth taking the time to write the review.

Do yourself a favor and save your money and your time. There are much more valuable options out there based on what I experienced here. My transmission still doesn't function correctly. I spent almost two years trying to get my Volkswagen Jetta's transmission fully replaced here. I paid upon pick up after about 6 months. Yes, 6 months. For the past almost year and a half, it has been dropped off and picked up probably 4 to 5 different times, after the initial 6 months. It sat up there for almost 4 months at one point. The only updates I get or ever got, is if I drove up there myself, or called directly. The shop may have reached out one time on their own over this entire process. I spoke to Sparky probably a month to 6 weeks ago, as I was still trying to get this rectified. I even took the option of selling the car itself to him or another business partner to just break even and get my money back, as it still does not operate correctly and cannot drive it. He promised to call me back, which I heard countless times throughout the span of this process. Not shockingly, I haven't heard anything back in those 6 weeks. I paid way too much money, have a car that doesn't run, and a shop that cannot give me the common courtesy of a phone call. I am currently seeing what legal action I can take at this point.

They did a transmission repair in Jan 2018 in our Chevy truck. This had to be redone in Nov 2019 which they said was not covered by warranty. May 2020 the second transmission went out and they refuse to honor warranty on work done in Nov 2019 stating they go by the first service date in 2018 even though it's the second trans they put in. On initial contact "Sparky" (the owner I believe) lied to me when I asked about him working with another company this trans job was contracted through. After that company got ahold of him he never returned my calls as promised. Horrible customer service. Non existent work ethic. Unbelievably rotten repair work if you can call it that. I would never recommend and would have given zero star rating if possible. This place should be investigated. Especially since they were unwilling to go over the paperwork with me or provide me a copy of this supposed paperwork.

Sparky is one of the most unprofessional business owners I’ve ever encountered. Refused to honor a warranty from a faulty job his business performed. Lied numerous times when all he had to say was that he did not want to do the job. There’s no place for anyone that operates that way within the business sector. Save yourself the time and energy and take your vehicle elsewhere. I would have given less than a star if it was an option ??

Lonestar transmission really took care of me! I was referenced by a friend to give them a call for some pricing. I was in a very bad situation with my 2015 Silverado it wouldn't even drive! Gave sparky a call, gave him a little background on my problem. I towed it there ALL THE WAY FROM WAXAHACHIE that's how high my reference spoke about sparky! calls me the next day and was very honest with me but with horrible news that I'm going to need a new transmission! Sparky assured me that the transmission they were going to install was going to be great and would run like new! The price for me was a huge investment but one that needed to be done. Sparky was understanding when I told him was going to need another week to acquire the funds. needless to say 500 miles LATER I FEEL AS IF I HAD MORE POWER THEN BEFORE!! Sparky was very honest and took great care of me and got my truck back to me in a great timely manner! it was a well worth investment for me! will do business here again!

This is the 2nd time I've come to Sparky and his great crew. First time was my 1994 k1500 for a clutch job and some other things, and I never had a single issue with the truck after that. 2nd time around for my now 1984 k10 pick up, which I plan on restoring. Lonestar has Definitely earned a lifetime customer for any of my mechanical maintenance I might come across in the future!

Sparky and his team did a fantastic job servicing my VW! They got me in and out quickly and even helped with a few other issues I was having! The staff is friendly, honest, and reliable... I will definitely be back!!!

Merely maintenance for me today. Complete transmission service and full flush. I do a lot of commuting every week, and I knew it was about time to get my transmission serviced. I looked around at a few different places before my dad recommended Lonestar. He said they were the best, most honest guys he'd ever dealt with. Truth! I'll never go anywhere else. With so many "mechanics" out there ready to scam you out of a quick buck (or a few thousand), this whole crew is here to actually help you. As a commuting college student, the unfortunate truth is that my wallet and my car can make or break me. Today, Lonestar kept both in great condition. I can't thank you guys enough! With this crew around, no one has any reason to let their car go out. There was nothing wrong with my car today, and I will keep going to Lonestar to keep it that way!

We dealt directly with the owner. He was very easy to work with. Honest. He knew what the problem was just by the information given over the phone. Quoted me a price before we left our truck, and that is exactly what I paid when it was over...not a penny more! Hope we never have to have another transmission fixed, but if we do, we will go to Sparky.

Sparky at Lonestar Transmissions is SUPERB!!! Excellent communication, customer service and first rate workmanship!! Sparky not only replaced our transmission but also tested it "himself" to make sure it was running and shifting the correct way too. Thank you again Sparky!!! We will make sure we always recommend you to our friends and family!!!

We dealt directly with the owner, Sparky. He patiently answered all of our questions about why we needed to replace our transmission on our toyota minivan. The price was fair and the warranty was exceptional. After the work was performed he personally took the time to test drive our van and didn't return it until he felt that it was done properly. Even when we brought it back with a concern, he looked at it and stood behind his work by correcting the minor issue. We would use Sparky again (though we of course hope to never need to again) and we would recommend his place to others.
