Update: 2 years later and car is still running like a top. Just wanted to update status in case anyone was curious. These guys really are the best and I am SO glad my transmission failed me in Corpus. I had the transmission go on my Lexus and with the good reviews I had it towed there for an estimate. Not only did they fix it perfectly but they offer a 3yr 75000 warranty (including parts and labor) which is much longer and better than most. The Lexus dealer was going to be more expensive and have a shorter warranty. They put it all back together and its running like a top! Plus I LOVE that the do all the rebuild work onsite... buying a rebuilt transmission from an unknown source is not a good idea and brand new OEM ones are very expensive. These guys seemed very honest and great to work with! read more

If you have money to throw away. It will cost $200 to get a diagnosis. When I asked what is wrong with it he said it needs to be redone for $3800. I knew that that's why I went there. ‍ and left. A n E would be the desired place. Didn't charge for diagnosis, fixing it for a lot less and was very detailed and kind about showing me what needs to be done. read more

Well my son had a new transmission installed a year ago and he lives near San Antonio, it has been giving him some problems lately. When he had it installed they said he could take it to a couple of shops in New Braunfels and they would honor the warranty. While he was here in Corpus for Christmas he took it in and they said he had to leave it for atleast a week and they would check it then. When he asked about the other shops in New Braunsfel they told him they dont do that, that only they could make the repairs and they were pretty rude and smart asses to him. I wouldn't recommend this shop to anyone. read more

Took my jeep in for what I thought was a transmission issue and it ended up being something completely different. They got my jeep fixed within a day. Very very thankful!!! Runs so much better now read more

An honest business. 5 stars all the way around. They stand by their word; so important these days. Jimmy and Luis are the men to see for virtually all of your auto repair issues. Please give them a call. You won't regret it. read more

This place is honest! They do good work and you can rest at ease knowing that they won't cheat you. They restored my transmission with a little TLC/maintenance and didn't charge me a dime since I didn't need a new transmission like I thought. I highly recommend this place! read more

Nice people; they helped us tremendously, at no profit to themselves. While on vacation from Mo., we had a blazer towed in; the problem was thought to be the tranny. We had to drive a rental car back to Missouri, and when Tracy told us over the phone that the transmission was NOT the problem - but a completely blown engine - we had to come back 800 miles w/ a car hauler to fetch the blazer. Greatstate kept the truck on their lot for nearly 2 weeks without charging us. They could have charged us hundreds for diagnostics and storage. Thank God we found these very nice people (this "vacation" cost a bundle) and you can certainly trust them with your cherished ride. read more

My car had a strange intermittent issue that was hard to diagnose. The repair was done and paid for and the car picked up in the morning several days later (part had to be ordered over the holidays). Later that night the issue came back. I took the car back in the next morning and they put it back in the shop immediately. Additional part was ordered and replaced at no additional charge, even though this part replacement would have cost more than what was done initially. The car has been driven over 1000 miles since with absolutely no hint of trouble. The manager Don was super friendly and understanding of my frustration - this was my 30mpg work car and while it was down I had to take my 15mpg SUV instead at 300-500 miles a day. My time, expense, and frustation and their integrity and quality service were obviously more important to them than the almighty dollar. Hats off to you, guys! read more

4th time using their service. Honest Folks. Told me once what everyone thought was a transmission issue - turned out to be faulty sparkplug wires. Rebuilt the automatic tranny in a 99 Mustang and I still drive it daily (191,100+ miles) Replaced the manual tranny on a 2003 Jeep - daughter still drives it. Offered advice on pulling driveshaft on a 2000 Jeep and refurbished the centering yoke (and saved me tons of $$$). read more

This is the SECOND time this company has saved me - thank you! Have a 2006 Jeep Cherokee that had all the warning lights on the dash 'on', the cruise-control not working, and 15 - 25% of the time the transmission would not shift from 2nd to 3rd +. Unless I stopped the car, placed in 'park', turned key 'off', and then re-start it and proceed again. Again 15 - 25% of the time it would continue to act up. (Note: at no time did it ever shift normally and 'then' start acting up while driving.). I had the vehicle towed to Aransas Autoplex in hopes they could diagnosis the issue (hoping it was caused by a wheel sensor). After Aransas Autoplex was NOT able to fix it, claiming "internal transmission issues and right-rear wheel/ABS sensor codes" - "which they said would 'NOT' contribute to transmission issue", and a $125. bill. I then had the vehicle towed to Greatstate Trans., told them what Aransas Autoplex told me, and asked them to diagnosed the issue. Terry assured me that the wheel/ABS sensor(s) very well could cause the transmission issues. So I ask them to replace the sensor(s). 30 hours later the car is fixed - bill, under $90. - AGAIN - GOD BLESS THESE PEOPLE - such a wonder company. "They even prayed for me and with me in hopes I would find peace with all the issues I have been having lately" - May God shine his light on all of you and your family's! {Come fall, I promise I will bring y'all a large pot of Cajun Chicken & Sausage Gumbo for lunch} *As far as the issue with Aransas Autoplex, be looking for my review in the future. I did stop by there and talked to the Serv. Manager as well as the General Manager about this story - leaving the conclusion up to them, and then walked out. - I will give them ample time to respond before posting the out come. ** Also see my review about Allen Samuel Dodge in AP *** I highly advice EVERYONE to post Reviews (good or bad) on YELP.COM, so we can find business (like Greatstate) we can still trust. read more

We were visiting from out of town and Don and the crew at Greatstate did everything they could to help us out and help us fast. They did a great job, at a great price and in speedy time so we wouldn't have to be in a hotel an additional night! Don and the team were honest, courteous and helpful, to be from out of town and receive this type of service was a Godsend! read more

(We've since moved from Corpus but I've been meaning to write this review for a long time now.) Anyway... how in the world does this place not have any Yelp reviews yet?? One would think that after witnessing the tremendous amount of thank-you letters pinned to their walls, that one could find the same outstanding reviews online. Hmmmm We've had the unfortunate misfortune of needing work done on our 2003 F150 on several occasions... but FORTUNATELY, we discovered Greatstate Transmissions. Everyone knows how difficult it is to find a dependable, honest mechanic who doesn't prey on people and won't take advantage of customers. If I had to choose one word to describe this place, it would be "trustworthy". Very long story short, Ford wanted to charge us an excess of $5,000 for a new transmission (with labor of course) yet Greatstate was able to complete the very same job for a fraction of that price at just under $2,000. We've had several other small issues with the truck's drivetrain and this quickly became the first place to call. I will say though, that my favorite part about visiting here isn't the service, it's the waiting room. The most sweetest dog and cat pair were always around to greet me... If you're not a pet person, don't worry, they're not "in-your-face" pets (is that even a good term for that? haha) so they won't bother you. If you're new to the area and/or are looking for a trustworthy place to have your vehicle serviced, I highly recommend Greatstate. They're friendly and truly do live up to their slogan: "Where Honesty and Integrity Still Matter." -Probably the very reason they've been in business for 35 years! read more

On november 2nd, i took my truck here to get my transmission worked on. My wife called them on november 6th to see what the status was on it and they told her that the receptionist was out for a couple of days so they didn't give us a courtesy call to let us know, and stated that they would get the part for my transmission until November 9th. They gave us a call on november 10th stating that it was ready. When we went to pick up my truck, I noticed ants in my center console and told them. The guy working stated that they had some "crazy ants" in the shop, but offered nothing to help get the ants out of my truck. By this time it was already 5:30 pm so I came home to try and get rid of the ants. I went on some errands the next day and noticed that there was a punch hole that left a small divet in my driver side rear on the body that was not there when we dropped it off. The truck is running well, but the customer service is way below par. read more
