ENGINE MAINTENANCE

Engine maintenance is vital to keep your car or truck operating at peak performance. It also impacts the longevity of your vehicle's engine. Trust the experts at AASTRO Transmission & Auto Repair to help you protect your investment. Call us or visit us at one of our convenient locations in Tucson, AZ.

These are some of the engine maintenance services we offer.

Diesel
Although diesel engines don't require tune-ups and tend to last longer than gasoline engines, they do require regular maintenance. Typical maintenance tasks include:

  • Changing the oil & filter
  • Changing the air filter
  • Changing the fuel filter
  • Bleeding the fuel system
  • Draining the water separators
  • Refilling the urea injection system

You can count on the experts at AASTRO Transmission & Auto Repair to help your diesel engine last a long time.

Fuel Injection
Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injector atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the engine. Make sure your vehicle's fuel injection system is maintained properly. For all your fuel injection maintenance and replacement needs, call or visit AASTRO Transmission & Auto Repair at one of our convenient locations today.

Ignition
An ignition system is a system for igniting (using an electric spark) a mixture of fuel and air in a gasoline engine. A properly working ignition system means a properly starting engine and high performance from your car. For all your ignition system maintenance and replacement needs, call or visit AASTRO Transmission & Auto Repair today.

Ignition Wires & Cables
Ignition cables also known as spark plug wires are an important part of your car's ignition system. They transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. The car will eventually fail to start. If it does start, it will run poorly. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine may vibrate. If your car needs new ignition cables and wires, call or visit AASTRO Transmission & Auto Repair in Tucson, AZ. Here, you will have the wires and cables changed by a top-rated mechanic.

Spark Plugs
A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven't been changed for a long time can cause ignition problems. At AASTRO Transmission & Auto Repair, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call or visit AASTRO Transmission & Auto Repair at one of our convenient locations today.

Oil, Lube, and Filter
To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles). When it is time for a lube, oil, or filter change, take your vehicle to AASTRO Transmission & Auto Repair in Tucson, AZ.

Check Engine Light
No one likes to see their car's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At AASTRO Transmission & Auto Repair, we can pull the code and diagnose the problem for you. Give us a call at one of our convenient locations or stop by the shop for our expert assistance.


What Our Customers Are Saying

Have used this location for years I had not been in in a long time then I got a call from Jimmy I had lost my keys about a month earlier with 2 key fobs for the handicap ramp about 200 dollars to replace. Someone brought them to him and he called me. The saved me a lot of money and have always been fair and honest. You have to remember if it sounds to high or you think it's not fair talk t them ask for options or get another opinion. But it does no good to complain afterwards never have they done anything without calling me ahead of time and getting approval. There is value in using the same garage they appreciate customer loyalty and get to know your vehicle better.

-Robert Crowl - Tucson,AZ.

I was impressed with the patience and time Jimmy showed in explaining the work my car needed. He walked me to my car and took the time to explain the part it needed and why. I was convinced I was at the right repair shop in AASTRO Transmission central location and highly recommend as conscientious and trust worthy.


-Jose Martinez - Tucson

After a vet appointment my dog and I were stranged on the west side after my SUV would not start. We were towed to AASTRO on Speedway and then shuttled home. By 4:00 I was home after getting a new Starter put in. Super quick same day service and hopefully over a year with this starting problem will be gone!! Yippee!


-duane gibson - Tucson

Great service


-Cesar Villarreal - San Antonio

George really took the time to explain my best options and the work was exceptional. They have followed up with me on the repairs several times. Great place to have any work done.


-James Hamblin - Tucson

I don't normally go out of my way to write reviews but the team James has built over at your Speedway location has always treated me very well, seriously knowledgeable and honest on whether a repair needs to be done immediately or can wait...it's honesty and service like that, that has made me tell my friends and family to get all repairs done there! Thanks for taking care of my car quickly and at a good price !!


-Zachary Anderson - Tucson, Az

My friend advised that I go the AASTRO Transmission on East Broadway and ask for John. He is a Master Mechanic and I was told he would run a diagnostic on my 2004 Lexus 330ES. I have 108K miles on it. When I brought it in I was thinking my transmission might be the problem (Sluggish, skipping during acceleration). Gloria was the gal at the front desk and actually asked John to come up front to meet me. She is an excellent representative and face for the business in meeting with the customers. I use Lexus of Tucson and also used a Mom and Pop shop for my 3K oil change. When I asked them about the sluggish performance they recommended that I use Premium gas. So, I have been doing that for a year but still couldn't out run my girlfriend's Prius. John has the capability and owns his own very expensive equipment to diagnose just about any car and along with that a very large TV screen to view the results. To make a long story short, John ran the diagnostics. He said I had a very well-maintained car but made a couple of changes and recommendations: He put back standard motor oil, he said based on the schematics and OEM recommendations of the 2004 Lexus to not use synthetic. In looking at my invoice the services provided: Motor Vac Fuel Injection & Decarb, which included: clean fuel injector, fuel rail, throttle body, combustion chamber and exhaust system all in compliance with OEM recommended maintenance. AASTRO did the 3K mile maintenance and I believe this shop automatically does a 41-point Inspection. I personally went back to see John's work station, tools and diagnostics area. Very impressive and clean. My invoice was around $300. So, now my car performs like never before, I find myself getting to the speed limit faster and getting to that speed without it skipping and not sluggish. I am so happy with my car and will continue to use AASTRO. I live by Ina Road and knew they had a shop there but my friend insisted I see John. My 3K mile oil changes will be done at this company but I will go to the Ina Rd shop. Anything major? Back to John. Oh, and on that note John also advised me that I could use regular as opposed to premium gasoline as per the Manufacturers' recommendation. I will save at the pump and I am grateful to my friend for the recommendation and appreciate John's incredible knowledge and passion for wanting to get things done correctly.


-PJ - Tucson AZ

Patrick and his team jumped on an unexpected problem with our Chrysler 300. The radiator cracked and we had just enough time to get it replaced. Between price, service and attitude I can't say which was better.
