Transmission Maintenance
Any car part manufacturer will tell you that preventive maintenance is critical to the part's lifespan. Like other auto parts, car transmissions aren't built to last forever. However, you can increase the transmission's lifespan by performing regular preventive maintenance. The easiest way to maintain peak performance and fuel economy is to provide regular transmission maintenance for your vehicle. To have your transmission maintained by experts, visit A&B Car Experts.

Transmission Replacement
In motor vehicles, the transmission usually refers to the gear box, which uses gears and gear trains to transmit speed and torque from a rotating power source to another device. You can have your car's transmission replaced with a new, rebuilt, remanufactured, repaired or used transmission. For more information contact A&B Car Experts in Round Rock, TX. Our experienced service technicians can help you make the best decision for your vehicle and your wallet.

Transmission Repair
Our services include transmission repair on both manual and automatic transmissions. The first step in getting you back on the road is assessing your transmission to accurately determine the source of the problem. In some cases, we are able to repair your transmission simply with adjustments, replacing external seals, or replacing accessible parts. To have this done by specialists, call 512-326-1085 to talk to the mechanics of A&B Car Experts today.

Transmission Repair and Rebuild
When it comes to automatic transmission repair, there are several options: buying a new one, buying a remanufactured one or having yours rebuilt. Each of the above options has its own share of advantages and disadvantages. Of the three options, rebuilt transmissions are the most economical. A rebuilt transmission involves removing the transmission from the car, disassembling it, replacing worn out parts, reassembling it, and then reinstalling it. To have this done by specialists, call 512-326-1085 to talk to the mechanics of A&B Car Experts today.

Transmission Flush
Although most manufacturers recommend a transmission flush every 30,000 miles or every two years, some symptoms may indicate that you need a transmission flush sooner. Some of the symptoms that indicate that your car needs a transmission flush sooner are: transmission grinding or strange noises, problems shifting gears, slipping gears, surging of the car, and delay in vehicle movement. Flushing the used fluid from the transmission washes away tiny particles of dirt, clutch material, and metal shavings. For all your transmission flush needs, call 512-326-1085 or visit A&B Car Experts today - we are transmission experts.

Timing Belt
A timing belt is a part of your car's internal combustion engine. The belt synchronizes the camshaft and the crankshaft rotation so that the engine valves open and close at the correct timings. Also, the belt prevents the piston from striking the valves in an interference engine. A timing Belt is a rubber belt that usually features teeth on the inside surface, while a timing chain is a metal roller chain. Most cars we drive now have timing belts instead of timing chains and gears. Although different manufacturers have their recommended mileage, you need to have your car's timing belt checked regularly. To have it checked by experts, contact A&B Car Experts today.

Cylinder Head
A cylinder head is the closed end of a cylinder (located in a car's engine block). It sits above the cylinder block, closing the top of the cylinder and forming the combustion chamber. The cylinder head coordinates airflow in and out of the engine. Since the cylinder head's chief function is to seal the cylinders properly, insufficient compression results in the car being difficult to drive. To have your cylinder head checked and repaired, talk to A&B Car Experts's cylinder head repair and reconditioning specialists today.

Cylinder Block
A cylinder block is the powerhouse for the motor vehicle. The solid cast car part houses the cylinders and their components (gaskets, valves, and seals) inside a lubricated and cooled crankcase. Since it is one of the most important parts of your car, the block is designed to be extremely strong and sturdy. Although strong and sturdy, the block is susceptible to failure resulting in a vehicle that won't start. Cracked blocks, porous blocks, core plug, or freeze plug failure are some of the problems facing cylinder blocks. Call 512-326-1085 to talk to the mechanics of A&B Car Experts about your cylinder block problems.

Authorized Jasper Dealer
Give Your Vehicle a New Lease on Life with JASPER. That big oil slick in your driveway or those strange noises from under your hood don't have to mean you'll be saddled with a new car payment soon. Instead, your trusted installer at A&B Car Experts can drop in a completely remanufactured JASPER gas or diesel engine, transmission or differential and get you back on the road again quickly! Call A&B Car Experts at 512-326-1085 to schedule an appointment. Proudly remanufactured in the U.S.A.

They even offered me a plate of food while I waited to check out when I went to pick it up. I'll definitely be back.

    Had my truck towed to their shop Monday night, and my truck was repaired and ready to go Tuesday afternoon. Great customer service.


  • -Dale S.

    Brought my 2003 Ford Mustang in for power steering leak and loud screeching noise. They tried four different power steering pumps to replace it, but they didn't charge me extra. They actually gave me a discount for the inconvenience.


  • -Lisa F.

    These guys are so awesome! I refuse to go anywhere else to have my car fixed.


  • -Monad

    Had a very pleasant experience. AC was not blowing, so I was given an estimate to change the fan. When the problem was fixed, I was told the fan is fine, and it was another minor problem and was charged a lot less! Thank you for your honesty. Excellent business.


  • -Monther A.

    Honest mechanic. Will only fix what's bad and not over charge or fix something that doesn't need fixing.


  • -Jay B.

    Ashraf is the best. I needed a quote for two older model Camrys, and he helped me get a quick estimate for cheap! I would highly recommend this place to all of my friends and family for their auto repair needs.


  • -Dorthey H.

    I was a little nervous about going to a new shop, but once I got there the guys were super nice. They were upfront and honest. I will go back if I ever need service again.


  • -Jay K.

    Very honest reviews. I came from dealer who told me my Prius need brake replacement and oil leak. Ashraf inspected it very carefully and told me there is nothing wrong with my car and did not charge me anything. He taught me how to replace cabin air filter, and I did it myself to save lots of money by buying parts from Auto Zone. I trust Ashra, and I will bring all my cars.


  • -P. S. E.

    A&B has always been super helpful and friendly even on short notice in their late working hours. So far I have been there a few times. I believe the staff (today I worked with Ashraf) truly care about their business' reputation and in turn offer honest, fast, and good work. Also, the lobby is comfortable with snacks, couches and phone chargers.


  • -Joe A.

    Don't judge a book by its cover. A&B may look like a busy, overcrowded neighborhood repair garage. However, the true judging of this facility is not based on curb appeal, but on their ability to perform a multitude of complex repair issues including exceptional body repair. A&B may be a neighborhood repair facility, but their capabilities and customer-focused service raise them above other shops where you are just a number and an invoice.


  • -Chris C.

    Ashraf and his guys take care of me every time. I trust him 100% with his recommendations. A&B changed the tires on my Hyundai Sonata, and they've been great. They've fixed the A/C in my Hyundai after taking it to another garage where they only temporarily fixed the issue. Needless to say I go to Ashraf and his team. I've also serviced my mother's Ford Fusion Hybrid and my good old Astro Van. Thank you for the great service.


  • -Bill R.

    These guy were great every step of the way. My car was towed to them and it fixed itself on the way!! They didn't charge me anything and still gave me advice and local places to buy parts. They do the right thing every time! Thank you.


  • -Austin K.

    I enjoy doing my own car work, however sometimes things don't go quite right, and I end up needing someone more experienced. Such was the case when the bolt on my catalytic converter broke. As the bolt is pressed in, it was much more difficult to work with. After several hours of using a punch on the bolt, drilling, and using torches, I decided it was time to give up and call a professional. I showed up early next morning at A&B, a recommendation from a friend, and Ashraf got my car up and immediately started work on it. In less than an hour he was done. He had a great attitude, was easy to work with, and had a reasonable rate. I am very happy with A&B Car Experts.


  • -Saad T.

    I've known Ashraf for over five years, and he is as honest a person as I've ever met. He takes pride in his work and provides excellent automotive advice. He only performs what is necessary, and you never have to worry about the workmanship. High quality service from a high integrity individual...what more could you ask for?


  • -Jordan H.

    Joe was great. I called one afternoon, and he was able to see my car the next morning and was done about an hour later. He replaced the motor so the window would work again. I couldn't pick the car up until later that day, and they didn't mind me leaving it there until I could get there. I highly recommend him as he does his work efficiently and at a great price.


  • -Shani S.

    Joe is a doll. I am sure he doesn't want to be called that, being a mechanic and all, but it's the truth. These guys are friendly, helpful, and their prices are more than fair. Need a used tire? Go here first. Need some auto work? Go here - these guys won't steer you wrong! We were stranded in Round Rock with a flat tire, they were right around the corner, and we scored a tire for a Jeep for just $35 that was in awesome shape. Thanks, A&B!!!


  • -Jessie T.

    I was very impressed with the service I got at A&B. I went in for a routine oil change and tire rotation and was helped quickly. The service took about an hour. The best part was that I wasn't bullied into any extra services. I told them what I wanted, and they gave me just that. When a problem arose with my car, they took me into the garage to show me the problem, but let me decide how to handle it without pressuring me into one decision or the other. At $45, the oil change and tire rotation was a bit more expensive than going to Jiffy Lube or another chain mechanic, but getting honest and courteous treatment is worth it to me.


  • -Melissa R.

    These guys are great! I don't feel pressured or like I'm minutes away from burning a hole in my wallet. They really value your loyalty, which means they will be honest! I came in a few months ago just for an oil change. Little did I know, I had a plethora of other issues. There was a rat nest that caused issues with my engine, there was a nail in my tire, and I had a dying battery. All of these issues weren't really a surprise, but I'm glad A&B looked at it. They even patched my tire for free! Again, great service...I will be back again!


  • -Amm W.

    After several visits, I actually feel comfortable trusting these guys with my car. I'm not easily impressed, especially when it comes to auto repair shops, but I have to admit these guys know what they're doing. I find their prices very reasonable & their work is professional and honest. They do get really busy sometimes so try calling them before you show up. They've always managed to repair my car in a timely manner. I hope it stays like this because the location is also very convenient to me.


  • -Abe S.

    Excellent knowledge about cars, honest at a very reasonable price, you can't possibly have it any better. A friend of mine told me about this place and that I should check it out, so I took my son's 2006 Dodge Charger to have front end work and alignment. Friendly guys, honest, they showed me what was wrong with the car. So, I got the best type of parts, which are made by MOOG, and they have a life time warranty and their prices are good. I am extremely happy with the service I got and definitely will go back. I would recommend giving them a shot and trying it for yourself. I promise you will not regret it.


  • -Amy T.

    BEST AUTO CARE PLACE IN ROUND ROCK!!! Everytime I have an issue, I call around to get quotes & I always end up here. They have saved me so much money! Not to mention the quality of work is the same or even better than the bigger places. I have decided this is the only place I will take my car. The guys are very friendly & tell you if they find something else wrong, but without pressuring you. Very professional service!
