About Hixson Transmission
Hixson Transmission is more than just a transmission shop. We also offer total car care for your vehicles. Here is a description of some of the services we offer. Please select a service from the dropdown menu or browse the entire list.

Oil Change – In about 12 minutes you will have your oil and filter changed.  We will also do a 21 point inspection on your car. 

Tire Rotation – You should have your tires rotated every 6,00 to 10,000 miles.  Properly rotated tires will ensure safe driving and extend the life of your tires.  A good way to remember to have your tires rotated is to rotate them every other oil change.

Brakes - Brake Inspection includes checking your brake:

  • pads (and/or shoes)
  • calipers
  • rotors (and/or drums)
  • wheel cylinders
  • hardware (springs and adjusters)
  • hoses
  • parking brake cables
  • fluid condition
  • wheel bearings and grease seals
  • master cylinder fluid exchange

Be smart about your brakes.  Have them checked once a year.  It will give you the confidence of being safe and the best opportunity to spot the necessary smaller repairs and avoid a bigger more expensive repair.  If you apply your brakes and are not stopping firmly, have your brakes checked immediately. 
Factory Scheduled Maintenance - Keeping up the maintenance on your car or truck? Fill in the form below to see the Manufacturer's Recommended Maintenance Schedule plus any available Recall or Technical Service Bulletin information for your vehicle.

Alignments -  Consists of adjusting the angles of the wheels so that they are perpendicular to the ground and parallel to each other. The purpose of these adjustments is maximum tire life and a vehicle that tracks straight and true when driving along a straight and level road. The symptoms of a car out of alignment are:  uneven or rapid tire wear, pulling or drifting away from a straight line, wandering on a straight level road or spokes of the steering wheel off to one side while driving on a straight and level road.

Wheel Balancing - Allows the tires and wheels to spin without causing any vibrations.  This is accomplished by checking for any heavy spots on the wheel-tire combination and compensating for it by placing a measured lead weight on the opposite site of the wheel from where the heavy spot is.  The symptoms of a car out of balance are: vibration in the steering wheel at certain highway speeds, vibration in the seat or floorboard at certain highway speeds and schalloped or cupped wear pattern on the tires.

Fuel System Cleaning - Over time, carbon deposits and tarnish can build up in the intake system causing parts to stick and prevent full range of motion. This can lead to performance problems, degraded throttle response, decreased fuel efficiency, rough idle, engine knocks and pings or even harmful emissions.  Poor engine performance can often be tracked back to the quality of fuel you purchase that could lead to fuel tarnish buildup and gumming in the fuel delivery system.  Benefits of fuel system cleaning are:  cleans fuel varnish, tarnish and gumming as you drive, improves performance on fuel injectors, carburetors, intake valves, manifolds, combustion chambers, fuel pumps and fuel lines, restores power and helps improve fuel economy, prevents engine knocks and pings, rough idle, and harmful emissions.

Headlight Restoration – If your headlights are yellow, scratchy or dull we can restore them to look like new again.  You will save a lot of money by restoring your headlights instead of replacing them.

Fuel Pump - When one or both fuel pumps (in the case of vehicles with two fuel pumps) stop working, fuel does not reach the injectors and the car will stall, just as if you ran out of gas. Electrical fuel pumps also use a relay and a fuse. If either the relay or the fuse blows, the car will stall as if it has run out of gas. Occasionally, a fuel pump will warn you that it needs to be replaced. It will overheat and stop working for 20 minutes or so. If you let the car sit for a half hour (more or less), it will start again, as the fuel pump cools off and begins working again. If you encounter this symptom, have the fuel system diagnosed to be sure it is the fuel pump and not the relay or wiring causing the problem, and have the offending part replaced.

Engines – Depending on the severity of the problem we can replace or repair the engine.  It can be something as simple has a gasket, O ring to total overhaul.  The engine is the heart of the car and just like your body, you have to make sure it is functioning properly.

Emissions Repair – EGR valve is part of the exhaust emission control system of the car. This car piece is very intricate and specific but it has a very important function that makes the car engine work with a much higher efficiency as well as helps avoiding that car gases affect the environment. EGR stands for Exhaust Gas Recirculation and this name directly refers to its function. This valve sends exhaust gases back into the combustion chamber by redistributing them through the intake manifold air stream. This way, this valve mainly works by taking exhaust gases to the best place. Besides the way in which it helps the car engine to work more efficiently, the EGR also contributes to the environment since it prevents car gases from causing smog.

Starters - Without a starter, a car will not be able to start. A car starter is found near the transmission, as it must extend the starter gear into the flywheel (flex plate for automatic transmissions). The flywheel or flex plate is a toothed gear that is attached to the back of the engine, between the engine and transmission. When the key is turned to the start position, an electrical signal is sent through the microchipped key (if applicable). The signal is then sent to the body ride control module or the computer (depending on the year, make and model of the car). The signal must then go through the burglar alarm, then through neutral safety switch, (if the car is a manual, through the clutch switch) to the solenoid, which pushes the bendix out, engaging the starter gear with the flywheel or flex plate and turning the gear. The starter gear turns the flywheel or flex plate, which in turn turns the engine over.  If the microchipped key does not give the proper signal, the car will not start. If there is a problem with the neutral safety switch (this switch does not allow the car to start unless it is in neutral or park), it will not allow the power to finish the circuit, and you have a no-start situation. If the burglar alarm is malfunctioning, or if the car was stolen without a key (hot wired), the power will not complete the circuit through to the starter and the car will not start.

Air Conditioning - The function of an air conditioner is to help remove the heat and humidity from inside the passenger compartment of the vehicle. Powered by a belt, the air conditioning compressor compresses the refrigerant to pressurize it and pump it through the system. The refrigerant is pushed through a valve where pressure and temperature are reduced. The now-cool refrigerant travels through the evaporator in the passenger compartment. As a result, cooled air is blown into your vehicle. This refrigerant returns to the compressor, where the cycle begins once again.  We will inspect the compressor drive belt, components, compressor, evacuate refrigerant, vacuum test the system and recharge the system.

Differentials – Helps cars make turns with ease.  The differential has three jobs: to aim the engine power at the wheels, to act as the final gear reduction in the vehicle, slowing the rotational speed of the transmission one final time before it hits the wheels and to transmit the power to the wheels while allowing them to rotate at different speeds.

Clutches – The clutch allows the transmission to power up.  A classic clutch symptom is slippage. Engine revolutions are not fully transferred to the transmission. Power is not fully transmitted to the drive wheels. The engine seems to race but the vehicle does not keep up! Slippage is most often caused by a worn clutch disc. Or, the clutch pressure plate may be weakened by heat, age, or abuse. In either case, it means the vehicle needs a new clutch. Worn or damaged clutches must be replaced.

Engine Diagnostics – If your check engine light is on, it’s time to bring it into the shop to have a computer hooked up to the car.  We will pull a report of codes to determine why the light has been engaged.  Often your car will let you know ahead of time when something is amiss by turning on the Check Engine Light. Unfortunately there are dozens of reasons for the light to come on. But checking the code will give you the answers as to why the light is on.

Radiator - A radiator is a type of heat exchanger. It is designed to transfer heat from the hot coolant that flows through it to the air blown through it by the fan. If your vehicle is more than five or six years old, you may notice that your engine is running a little hotter that it used to, you may have radiator problems or be in need of a dreaded radiator repair. You might even find at the end of the day you are in need of a complete radiator replacement. You should expect to start having radiator problems by the time your car enters its sixth year of life. It doesn't matter whether the odometer reads 500 miles or 50,000. The fact is that over time, environmental factors such as humidity, road salts and debris, hard water and chemical reactions will take a toll on the metal from which your radiator is constructed giving you radiator problems. Eventually, corrosion and rust sets in, and/or mineral deposits build up inside the narrow tubing in the core, constricting the flow of coolant. The epoxy that is used to join many seams also typically wears out after four or five years, these are all typical radiator problems, leading to a need of radiator repair.

Timing Belts – Timing belt breakage is the common reason for cars breaking down.  A timing belt, timing chain or cam belt is part of an internal combustion engine. It connects the crankshaft to the camshaft(s), which control the opening and closing of the engine's valves.  A timing belt will usually last anywhere from 60,000 to 150,000 miles.  While having the timing belt replaced, you should also consider replacing the water pump, belt tensioner, thermostat and camshaft seals. They'll probably already be worn or about to wear out. Replacing them at the same time as your timing belt can save you money on labor and save you extra trips to the mechanic.

CV Axles - Your vehicle’s axle delivers power from the transmission to the drive wheels. The axle has only one weak point: the CV joints. The CV joints, or constant velocity joints, allow the axle to flex while the vehicle turns left or right. The joint is covered by a boot, called a CV boot. When this boot rips, axle grease leaks out of the joint and the joint dries out and grinds on itself. At this point, the axle will fail.

Suspension - Your car's suspension system is an intricate network of cooperating (usually, anyway) components designed to give you a smooth, even, stable ride. Since the suspension is ground zero when it comes to road abuse, the parts wear out, and even break. If your car doesn't seem to ride like it used to, you may have a problem. Symptoms may include: hear a rattling noise on a bumpy road, abnormal tire wear, your car may feel like you are floating or your car pulls to the right or left when braking.

Shocks/Struts - Short of its wheels and tires, a car’s struts are the single largest and most important part of its suspension system. The struts are essentially combination shock absorber and spring packages (also called a coil-over strut) with a large leg on the bottom connected to the wheels' steering hub. Struts act as the upper control arm in the car's suspension system. You may feel like the car is floating, or you have uncontrolled wheel movement or even by bottoming out.

Coolant System Flush - Performing a coolant flush and fill will prevent overheating - the most common cause of breakdowns and internal engine damage.  We recommend flushing your coolant system every 30,000 miles.  Of course, follow your manufacturer’s guidelines.

Transmissions - The transmission is a critical part of your vehicle’s drive system. Transmission failure typically means the car can't be driven until the transmission is fixed or replaced. Both manual and automatic transmissions share many of the same trouble signs that signal transmission problems or failure. Being alert to early warning signs may help you avoid costly repair bills and significant safety issues.  Rough shifting abrupt or hard shifting between gears is the most common sign of transmission problems. Fluid is dark or dirty is another key to potential transmission problems, but it doesn't necessarily signal imminent doom. Small stains or drops of fluid beneath the vehicle may not be a problem, but wet spots and puddles deserve immediate attention. Running your vehicle with low or no transmission fluid is a sure way to end up with a new transmission. A rhythmic, heavy-knocking sound can indicate transmission problems. Grinding when shifting gears is another indication of problems. "Slippage" is when the engine speeds up but the vehicle doesn't respond accordingly. It is a sign of a failing transmission. A delayed or missing response when shifting gears is a sure sign that your transmission has failed or is failing. If you are experiencing any of these symptoms, you need immediate repair. 

Tune ups - Regularly scheduled opportunity, usually once a year, to do all of the preventative maintenance that needs to be done. Ensuring that your car gets a tune up regularly will help maintain the performance of your car and extend its life.  A tune up generally includes replacement of several parts on your car. These parts may seem superficial, but failing to replace them regularly can cause decreased performance in your car, and may even lead to other problems. For example, an air filter should be replaced at least once a year; failing to replace it when it's dirty will cause your engine to get less and less of the air it needs to run properly. If the problem is left unattended, the air-fuel mixture will continue to run richer and richer —- meaning that there will be too much fuel and not enough air in the mixture —- and eventually cause other parts to fail.

A tune up should involve replacing the air filter, replacing or cleaning the spark plugs, and replacing the distributor cap and rotor. A tune up can also include replacement of the spark plug wires, fuel filter, PCV valve and oxygen sensor.  Of course, always check what’s recommended by the manufacture. 

Tires – The way your tires wear is a good indicator of other parts of your car.  Abnormal wear patterns are often caused by the need for simple tire maintenance, or for front end alignment.  Tires should be inspected at every opportunity. 

Water pumps - All-important water pump, shoots coolant through the your car's cooling system. It's driven by a belt and operates only when the engine is running. Water pumps fail with some regularity--you can expect to replace yours sometime before 100,000 miles.  

Alternators - The electrical system is one of the most important components; critical to the proper operation of various electrical devices and the smooth operation of the engine. The alternator is an integral part of the electrical system, and its failure can stop the operation of the entire vehicle. Understanding the warning signs of car alternator problems will help to avoid expensive repairs and inconvenient breakdowns. One of the symptoms first noticed when an alternator is failing is dimming or flickering headlights, which could indicate that alternator is not generating enough electricity to power the vehicle’s electrical system. As engine speed is increased or decreased, the headlights will brighten and dim as a weakened alternator's current output rises and falls. A healthy alternator will keep headlights bright regardless of engine speed.  Electric clocks, tape players, power windows, power seats and other electrical accessories within a vehicle depend upon a steady supply of electrical current to operate correctly. A failing alternator will cause windows to open and close slowly, clocks to slow down or lose their settings and power seats to operate slowly. The car's battery relies on the alternator to keep it fully charged at all times. Each time the vehicle is started, the battery uses some of its charge to turn the engine over. That charge is replaced by the alternator when the engine is running. An incorrectly operating alternator will not be able to keep the battery fully charged, resulting in hard starting or a dead battery. Alternators have several important moving parts. Inside an alternator are bearings critical to the alternator's smooth operation. Squealing, howling or grinding noises coming from the alternator are indicators of bearing failure and eventual failure of the entire alternator unit. Modern cars require a steady electrical current of specific voltage in order to run properly. The engine's computer, ignition system, fuel system and emissions system all rely on electricity supplied by the alternator to operate correctly. Drops in electrical output from a failing alternator can cause these systems to malfunction, leading to a poorly running engine. Symptoms will be rough idle, misfires, poor acceleration, hesitation and stalling.
