Transmission Maintenance

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 AASTRO Transmission & Auto Repair in Tucson, AZ. 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 520-325-5500 to talk to the mechanics of AASTRO Transmission & Auto Repair 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 one of our convenient locations to talk to the mechanics of AASTRO Transmission & Auto Repair 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 or visit AASTRO Transmission & Auto Repair at one of our convenient locations today - we are transmission experts.

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 AASTRO Transmission & Auto Repair's cylinder head repair and reconditioning specialists today.

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 AASTRO Transmission & Auto Repair 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 one of our convenient locations to talk to the mechanics of AASTRO Transmission & Auto Repair 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 AASTRO Transmission & Auto Repair can drop in a completely remanufactured JASPER gas or diesel engine, transmission or differential and get you back on the road again quickly! Call AASTRO Transmission & Auto Repair at one of our convenient locations to schedule an appointment. Proudly remanufactured in the U.S.A.


What Our Customers Are Saying

Monica and Jimmy are awesome. Very friendly easy to work with. Working with them in a car trouble situation made it so much easier!! Thank you both


-Nicole - Tucson, AZ

First time customer that is really impressed with the service and stick-to-itiveness. I brought a complex issue to Jimmy and his team and they stayed with it communicating to me their process each step of the way.


-Neal - Tucson

Excellent, knowledgeable service for a complicated mechanical problem, as well as problems with door latch mechanisms that other service centers were not willing to even take a look at.


-Troy - Tucson

Very competent team at this Broadway location. They consistently solve very difficult repair problems. They never give up. I had an intermittent electrical/computer issue that was very hard to find. George and his team found it and fixed it. They even searched for the best price on all the parts and passed on substantial savings to me. They are the "go-to" experts for vehicle repairs and always have a great positive attitude. Highly recommended.


-John Hufault - Tucson AZ

Excellent service. They solved a very difficult intermittent electrical/computer problem. This is the "go-to" team for many vehicle repairs. They never give up and have always solved the toughest problems and always have a great positive attitude. Reasonably priced. Highly recommended.


-John Hufault - Tucson, AZ

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. They saved me a lot of money and have always been fair and honest. You have to remember if it sounds too high or you think it's not fair talk to 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.


-Edward Hankins - Az

Just wanted to say how wonderful and happy I am with the service you did on my vehicle!!! George and the team are honest and trusting and do the job right!!!! THANK YOU FOR EVERYTHING!!! ALWAYS SATISFIED WITH THE WORK AND WILL ALWAYS COME BACK!!!


-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 stranded 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.
