A/C Repair

Driving in Texas heat without a working A/C is miserable. Hot air blowing from the vents makes every trip uncomfortable. It is hard to focus on the road when you are sweating through your seat.

A failing A/C can point to deeper problems. A refrigerant leak, a bad compressor, or a clogged condenser can all cause your system to quit. Left alone, these issues only get worse and cost more to fix down the road.

Our technicians diagnose and repair all A/C problems fast. We use advanced tools to find the exact cause and fix it right the first time. Common issues we handle include low refrigerant, compressor failure, condenser problems, blower motor faults, and cabin filter blockages. You will stay cool all summer long.

Beat the Texas heat. Call (903) 892-4767 to schedule your A/C repair today.

Air Filter Replacement

Your engine needs clean air to run well. A clogged air filter chokes your engine and hurts fuel economy. Most drivers never think about it until the damage is already done and the costs start to add up.

A dirty filter forces your engine to work harder than it should. Over time, that extra strain wears down parts faster. You end up paying more at the pump and more at the shop. It is an easy and affordable problem to prevent.

At Alpha Transmissions & Automotive, we inspect both your engine air filter and cabin air filter. We replace them quickly using quality parts. It is one of the simplest ways to protect your vehicle, improve performance, and keep the air inside your car clean and fresh.

  • Engine air filter inspection and replacement
  • Cabin air filter replacement for cleaner interior air
  • Fuel filter checks and replacement
  • Fast service with quality parts at competitive prices

Keep your engine breathing clean. Call (903) 892-4767 to schedule an air filter check.

Battery Repair

Few things are more frustrating than a car that will not start. A dead battery leaves you stranded at the worst possible moment. It disrupts your whole day and can leave you in a tough spot.

Battery problems sneak up on you. Slow starts, dim headlights, and dashboard warning lights are all early signs. Ignore them and you risk getting stuck far from home with no help in sight.

Our team tests your battery quickly and tells you exactly what it needs. If a replacement is necessary, we install a quality battery and make sure every connection is clean and secure.

We also check your alternator and charging system to make sure everything is working together properly.

  • Battery voltage and load testing
  • Terminal cleaning and corrosion removal
  • Battery replacement with quality brands
  • Alternator and charging system inspection

Do not get stranded. Call (903) 892-4767 to have your battery tested today.

Brakes & Brake Repair

Your brakes are the most important safety system on your vehicle. When they start to fail, every drive becomes a risk. Squealing, grinding, or a soft pedal are signs you simply cannot afford to ignore.

Worn brake pads do not stop wearing on their own. They damage rotors, calipers, and brake lines over time. What starts as a simple pad replacement can turn into a much larger and costlier repair if you wait too long.

Alpha Transmissions & Automotive provides complete brake services for all vehicles. We inspect every part of your brake system and only recommend what you truly need. Your safety is always our top priority, and we stand behind every repair we make.

  • Brake pad and shoe replacement
  • Rotor resurfacing and replacement
  • Brake fluid flush and refill
  • Caliper inspection and replacement
  • Anti-lock brake system (ABS) diagnostics
  • Brake hose inspection and replacement

Do not risk your safety. Call (903) 892-4767 for a full brake inspection today.

Check Engine Light

That little orange light on your dashboard can mean dozens of things. Most drivers feel a knot in their stomach the moment it comes on. Not knowing what is wrong is stressful and unsettling.

Driving with the check engine light on is a gamble. It could be something as simple as a loose gas cap or something serious like a failing catalytic converter. Putting it off can turn a small, inexpensive fix into a very costly repair.

We use advanced OBD-II scanners to pinpoint the exact problem fast. Our technicians do not guess. They find the root cause and fix it properly. We explain everything in plain language before we start, and we give you upfront pricing so there are no surprises.

  • Advanced OBD-II diagnostic scanning
  • Oxygen sensor testing and replacement
  • Catalytic converter inspection and repair
  • Spark plug and ignition system service
  • Emissions system diagnosis and repair

Check engine light on? Call (903) 892-4767 to get it diagnosed right away.

Electronics Repair

Modern vehicles rely on complex electronics to operate properly. When sensors, modules, or wiring fail, your car behaves unpredictably. Warning lights appear, systems stop working, and every drive becomes uncertain.

Electrical problems are tricky to diagnose without the right tools and training. Many shops guess and replace parts that do not solve the real problem. That wastes your time and your money and leaves you right back where you started.

Our technicians use the latest diagnostic equipment to trace electrical faults with precision. We service computer systems, sensors, engine controls, and wiring.  We find the real problem and fix it right the first time, saving you both time and frustration.

  • Engine control module (ECM) diagnosis and repair
  • Sensor testing and replacement
  • Wiring and electrical fault diagnosis
  • Drivability and performance diagnostics
  • Power window, lock, and accessory repair

Electrical issues slowing you down? Call (903) 892-4767 to book a diagnostic today.

Engine Rebuild

Engine trouble is one of the most stressful things a car owner can face. Knocking sounds, burning oil, or a sudden loss of power are serious warning signs. When your engine starts to fail, it can feel like your vehicle is done for good.

Replacing an engine outright is very expensive. But continuing to drive a failing engine only makes things worse. Every mile adds more damage and drives the final repair cost higher and higher.

A professional engine rebuild from Alpha Transmissions & Automotive can restore your vehicle to peak performance. We disassemble the engine completely, inspect every part, replace what is worn, and reassemble everything to factory specifications. The result is an engine that runs like new at a fraction of the full replacement cost.

  • Full engine disassembly and component inspection
  • Replacement of worn gaskets, seals, and bearings
  • Valve and timing system service
  • Engine balancing and precision reassembly
  • Post-rebuild performance testing and verification

Fuel System Repair

Hard starts, stalling, and poor fuel economy are signs your fuel system may be struggling. These problems make your vehicle unreliable and unpredictable. You never quite know when it might leave you stranded on the side of the road.

Fuel system problems compound quickly when ignored. A clogged filter stresses the fuel pump. A failing pump damages the injectors. What begins as one small issue can turn into several costly repairs if left unaddressed for too long.

We diagnose and repair all fuel system problems at Alpha Transmissions & Automotive. From fuel filters and pumps to injectors and fuel lines, we handle everything. We use quality parts and provide honest pricing before any work begins so you always know what to expect.

  • Fuel filter replacement
  • Fuel pump diagnosis and replacement
  • Fuel line inspection and repair
  • Fuel system leak detection
  • Full fuel system performance testing

Fuel system problems? Call (903) 892-4767 and let our team fix it right.

Oil Change

An oil change is the simplest thing you can do to protect your engine. Yet many drivers put it off for far too long. Old oil loses its ability to lubricate, and engine damage builds up silently over time.

Skipping oil changes causes friction and heat to build up inside your engine. Parts wear down faster than they should. Eventually, the engine seizes up. What could have been a routine service call turns into a very costly engine repair.

We make oil changes fast and affordable at Alpha Transmissions & Automotive. We also inspect your filters, fluids, belts, hoses, and tire pressure while we are at it. It is a full vehicle check, not just a simple drain and fill.

  • Conventional, synthetic blend, and full synthetic oil options
  • Oil filter replacement with every service
  • Full fluid top-off and underhood inspection
  • Belt and hose condition check
  • Tire pressure inspection

Protect your engine. Call (903) 892-4767 to schedule a quick oil change today.

Preventative Auto Maintenance 

Most car problems do not happen overnight. They develop slowly and quietly over time. Drivers who skip routine maintenance often face sudden and expensive breakdowns that could have been avoided entirely with simple upkeep.

Waiting until something breaks always costs more. A worn belt that snaps can destroy your engine in seconds. Low coolant can cause your car to overheat on the highway. Small issues become big emergencies faster than most people expect.

Our preventative maintenance program keeps your vehicle ahead of problems. We inspect the systems most likely to fail and catch issues before they get worse. Think of it as regular health care for your car. A small investment now saves you significantly later.

  • Comprehensive safety inspection
  • Oil and filter service
  • Coolant system check and flush
  • Brake system inspection
  • Battery health check
  • Belt and hose replacement at recommended intervals
  • Transmission fluid inspection
  • Tire inspection for wear and pressure

Stay ahead of breakdowns. Call (903) 892-4767 to schedule a full maintenance check.

Tune-Up Service 

A car that struggles to start, idles rough, or burns more gas than usual is telling you something important. These are classic signs your vehicle needs a tune-up. Ignoring them leads to more fuel costs and more wear on your engine every single day.

Worn spark plugs, dirty filters, and aging ignition parts make your engine work harder than it needs to. Over time, this leads to misfires, sluggish performance, and unexpected breakdowns at the worst possible moments.

A tune-up at Alpha Transmissions & Automotive covers everything your engine needs to perform at its best. We inspect and replace the components that directly affect performance and fuel efficiency. After a proper tune-up, your car will feel noticeably smoother, more responsive, and more fuel-efficient.

  • Spark plug inspection and replacement
  • Air and fuel filter replacement
  • Distributor cap and rotor check
  • Ignition wire inspection and replacement
  • PCV valve replacement
  • Timing and idle speed adjustment
  • Full fluid and belt inspection

Is your car due for a tune-up? Call (903) 892-4767 to schedule yours today.

Transmission Service

Your transmission is one of the hardest-working parts of your vehicle. It shifts through gears hundreds of times on every single drive. Without proper maintenance, it wears down over time and can eventually fail completely.

Transmission failure is one of the most expensive repairs any driver can face. Dirty or low fluid speeds up wear on internal components. Many drivers do not notice a problem until serious damage is already done and repair costs have gone through the roof.

Regular transmission service at Alpha Transmissions & Automotive keeps your transmission healthy and shifting smoothly mile after mile. We flush old fluid, replace filters, inspect seals, and look for early signs of wear. Catching problems early can save you thousands of dollars in the long run.

  • Transmission fluid flush and refill
  • Transmission filter replacement
  • Seal and gasket inspection
  • Transmission diagnostic check
  • Repair and full replacement services available

Protect your transmission. Call (903) 892-4767 to schedule a transmission service today.

Frequently Asked Questions About Auto Repair Services

  • How do I know when my car needs to be serviced?

    Warning lights, unusual noises, rough idling, poor fuel economy, or difficulty starting are all signs your car needs attention. When in doubt, bring it in for a quick diagnostic check.

  • How often should I get an oil change?

    Most vehicles need an oil change every 3,000 to 5,000 miles. Vehicles using full synthetic oil may go up to 7,500 miles. Always check your owner's manual for your specific interval.

  • What does a tune-up include?

    A tune-up typically includes replacing spark plugs, air and fuel filters, and ignition components. It also covers a full inspection of belts, fluids, and engine performance systems.

  • Is it safe to drive with the check engine light on?

    If the light is steady, schedule a diagnostic soon. If it is flashing, stop driving as soon as it is safe and call us right away at (903) 892-4767.

  • How often should my transmission be serviced?

    Most vehicles need transmission service every 30,000 to 60,000 miles. Towing, driving conditions, and vehicle age can all affect that interval.

  • Can I skip tire rotation if my tires look fine?

    Tires can look fine on the surface while wearing unevenly underneath in ways that affect handling and safety. Rotating every 6,000 to 8,000 miles is the best way to get the most life out of them.

  • Does a weak battery affect other systems in my car?

    Yes. A failing battery can strain the alternator and cause electrical issues throughout the vehicle. A simple battery test can catch problems before they leave you stranded.
