David at Sonny's Transmission is a true hero. He was able to fix my son's Hyundai Tiburon Automatic Transmission for a 1/3 of what the Hyundai dealership or AAMCO quoted me. He even warrentied it for 50,000 miles, something the above two laughed at when I asked if they could offer it. Sonny's Transmission is a small family owed business with heart and soul. Keep up the good work. read more

Ok..This place can really be good..my transmission was in need of major work...mind you this was two years ago..When it was done I had to put my car up due to money problems...over 1700 bucks in repair and that was all I could do at the time. It sat for the next two years .. Finally raised enough money to get my tags and new plates..drove the car to the tax office and what happens..the tranny goes out..Im really freaking now..took it back and found out that the service advisor was ripping this place off...that didnt fix my problem..found that he forged false paperwork for my car and more than likely pocketed the money.... I came in with hell fire in my heart and my boots for kicking..but the owner was there..I told them how the hell can my trany break again just sitting there...now the warranty was expired...It never had been driven more that 25 miles before I was stuck again....they took a look and found the problem...speed sensor..easy fix. I also had leaking lines..both uper and lower trans lines..which i payed for them to fix before and they never did but said they did..bunch of b.s..also when they removed the trany i had a skid plate that was taken off and never replaced..there were so many other parts that were missing on my car that it was a wonder my car still held itself together....brackets screws and a lot of little things...they replaced motor mounts which was a needed thing but all the wire harnesses were replaced wrong and torn from the black wire cases...sloppy sloppy work..but this was done by an idiot two years ago....I had to replace the tranny lines myself because it wasnt done the first time I payed for it..so more money out of pocket.....and I wasnt about to let them work on my car ever again. If your looking for transmission service...well dont be me...go else where....I wasnt treaded any better by the owners...more like they didnt want me there...of course not...who wants someone there whos car they screwed up.... All repairs that were made were made by my hands...these guys may be nice in your face but...they'll stickcit too you when you turn your back....buyer beware.... The owners. Well they try to help but what can you do...this can be a good place..just watch who your dealing with there. read more

My Mazda Miata would not shift into 3rd gear. I visited two other major transmission shops where they quoted me $2800-$3000 without even test driving or opening the hood. Anthony at Sunny's Transmission took the time to test drive my car while I waited and performed a diagnostics check. The repair to my transmission came to a total of $1900. I appreciate the time taken to diagnose the extent of the problem before quoting me a price. It is refreshing to find a business like Sunny's that actually respects the customer and provides honest and dependable service. read more

Good work overrall. The only problem I have is with the customer service. We arrived to pickup vehicle and it was dirty on the inside. My bf simply asked about the cleanliness of the vehicle and the employee said "what do they expect ...their cars to look perfect." No, but as a paying customer I expect that you at least wipe off whatever you greased up. I totally understand that mechanics get greasy, but wear gloves and place some protective paper on mats on floorboards. read more

I brought my van in for a quote to repair transmission. Still working when I stopped. It did have issues. David took it for a test drive. Left, and got less than 1 mile from shop, transmission totally out. Towed in and told 3 or 4 business days, it took a week. Said was ready, picked up, grease all over seats, carpeting door panels, and car body. Got home, transmission not shifting right. Brought right back, transmission was not bolted in properly. Sheared new power steering lines ( less than 2 weeks old). Also making squealing noise from wheel. They bent a piece of metal and was rubbing on my rotor. NOT HAPPY! Said was fixed, picked up. Still not shifting right. Took 8 days to get back. Said they were ordering parts for it. When picked up, said mechanic said nothing wrong with it. Still not shifting right. At my mechanics shop today checking it out, and he agrees still not shifting right. I asked for a list of parts installed in transmission and got nothing from Elizabeth. Not done with this yet. Hello BBB! I would save yourself the frustration and stay away from this shop! I have a warranty, but what good is it if they can not fix it right the first time! read more

DO NOT take your vehicle to these people; they do not honor or stand by their "warranty". They fixed our transmission and less than 45 days later, while traveling through San Antonio we had problems with the first gear slipping. We took it in to a mechanic and our transmission was burnt; all gears burnt and was beyond repair. We called Sunny to report the problem. Per David, "can't do nothing for you because you're out of town, only guarantee if you break down in Dallas". This is bad business on part of their poor workmanship. Don't go these rip off artists, unless you only drive your vehicle in the city of Dallas. read more

My car needed the clutch replaced and Anthony at Sunnys quoted $800, much better than $1450 another shop quoted, so I agreed and left my car. But the next day he asked for $400 in cash up-front so he could order the parts, which was pretty worying. A few days later he added $400 to the price because he also had to replace some hydraulics. When the work was completed I asked to see the old parts, but Anthony wouldn't show them to me because they were needed for core charge reimbursement. In the end, the price was $1197, still cheaper than the other shop. The car is running fine so far, but the entire time I felt I couldn't trust him. read more

To whom ever live In the DFW area im warning DO NOT take your car to this shop for any repairs. I have a 2006 Mercedes E350 that I took to this shop November 17, 2014 to be place on their diagnosis machine to tell me why my Check Engine light was on. After having my car which was drive able and running at the time the guy Allen called me to inform that a Valve in my transmission was bad and they could rebuild my transmission for 3785. After giving them the okay to do the work on my car they tagged me along 4 whole months before telling me to come get my car then couldn't fix. I went and had my took to the dealer where they have shown me more then enough proof where this shop basically thru my transmission back in my car placed parts off of another Class Mercedes on my car an everything and the shop is not willing to own up to their mistakes so Please Run As Fast As You Can from Sunnys Transmission 9811 Ferguson Rd Dallas Tx. If I could give a (-0) I would be more then happy too. read more
