Engine Replacement
The engine converts energy into useful mechanical motion. This amazing machine is what keeps your vehicle moving. Although generally reliable, a car engine is susceptible to damage and breakdown.

Engine Repair and Rebuild

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 JayBees Auto Service.

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 JayBees Auto Service in Tucson, AZ. Our experienced service technicians can help you make the best decision for your vehicle and your wallet.

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 520-790-6035 or visit JayBees Auto Service 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 JayBees Auto Service 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 JayBees Auto Service'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 520-790-6035 to talk to the mechanics of JayBees Auto Service 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 JayBees Auto Service can drop in a completely remanufactured JASPER gas or diesel engine, transmission or differential and get you back on the road again quickly! Call JayBees Auto Service at 520-790-6035 to schedule an appointment. Proudly remanufactured in the U.S.A.


What Our Customers Are Saying

My family has been going to JayBees for decades (yes, decades), and we trust them implicitly. (Woman owned and operated if that makes a difference to you.)


-Jonathan F.

Great people here...!!! With the best customer service. Always a pleasure seeing them.


-Peggy R.

The people at JayBees are incredibly helpful and honest. As a woman, I'm used to being talked down to because it's assumed I won't understand. Shelly specifically always makes sure I understand the problems and the options for repair. They also have a courtesy shuttle so I can get a ride to my friend's house and don't have to pay for another ride option. I will never go anywhere else to get my car fixed.


-Sara T.

Love JayBees! Honest and reliable. Highly recommend.


-Michele T.

Shelly, Jacqui, and Doug....you're the BEST!!


-Eddie C.

Skilled mechanics, courteous.


-Thom M.

Jacqui and Doug are both amazing. Most trustworthy auto mechanic I've found. Time and time again they prove this to me.


-Joe F.

The people I've had contact with are very friendly, and my husband trusts their work.


-Lynn C.

Great service and honest prices.


-Quinny M.

Fair prices, and they do the little extra things to make sure your car or truck is fixed and safe.


-Bill G.

Great service and an amazing staff. They very patiently walked me through the steps they took to diagnose, troubleshoot and resolve my car's issues.


-Todd M.

Very happy. Came in for oil change. They checked over the whole vehicle for me and found a couple of minor repairs needed so I had them do a couple of them, and will return for the others in the near future. My second visit to them. Last fall they repaired a faulty engine control computer for me, but this was a difficult undertaking because Chrysler-Fiat (Dodge Owners) don't make that computer anymore. They found a company back east that remanufactures old out-of-production car computers and got the job done.


-Ken

My car wouldn't start and had to be towed to JayBees. I feared it was something like an alternator or battery problem but was surprised to learn it was a defective key. The courteous and knowledgeable staff always make me feel I am in good hands. Everyone I have referred to JayBees has thanked me. Wow, 30 years in the business. That says a lot.


-Patty D.

Jacqui and Shelly are such experts with car service, and I trust them completely. They have proven to go above and beyond to explain their findings about the work needed and not needed for my car. I am so appreciative of all of their time and effort to explain and assess everything for me. They are honest, do quality work, and are reliable - what more do you need?


-Michele J.

I love JayBees! The staff is so friendly and honest. I always feel comfortable spending money on the repairs that they recommend, because I know that they have my best interest in mind. We had quite a few repairs this visit and Shelly went through every single thing with me to make sure that I knew what I was paying for. I am super happy with the work. Thank you!


-Amy C.

Very thorough and honest place. Will be the place we are going to in Tucson for any problems with our cars from now on.


-Terry & Thomas

Routine oil change and recommended maintenance items. Friendly and knowledgeable staff and technicians. To be in business 30+ years means they are doing things RIGHT. Everyone I have referred to Jaybees has thanked me.


-Patrice P.

Replaced the broken driver's inside door handle, plus had an oil change/service & vehicle inspection/evaluation. Have gone to JayBees for years. Excellent service. Ultra-competent. Super honest. Really good people to do business with!


-J L

The personnel and mechanics at JayBees are very efficient and work in a timely manner. I was able to get an oil change and have the car travel-ready within a matter of hours. The mechanics are very thorough and check all the little details to make the car roadworthy. If they find a detail that needs extra work, they immediately contact you to let you know and have you give them the okay. I appreciate this extra effort.


-Judith S.

JayBees is always friendly, courteous and they do an excellent job. I've been going to them for 25 years, and I don?t trust anyone else.


-Cindy F.

Jacqui and Shelly and all the people here are awesome. I'd never go anywhere else.


-Anita R.

We were recommended to JayBees by some friends, and we were not disappointed. Not only did they expertly repair the problem, but they also gave the vehicle an overall service inspection at no extra charge. Their mechanics gave us several recommendations for future service needs, but no one pressured us into having things fixed right then and there. We will definitely take our vehicles back to JayBees for maintenance and repairs.


-Nancy B.

By taking the wife's Murano to JayBees instead of the dealer, we saved well over $1000.00 in parts. They fixed the electric system and also got the electric motor to work, which we had been quoted almost a thousand dollars parts and labor. Plus the fix on the electric system that had caused the car not to start saved us another several hundred. Plus they treated my wife like a person instead of like a dummy and making her call and ask her husband. They explained and showed her what was needed to be done.


-Bill G.

Great central location. Good people who want the best for your automobile!


-TK H.

Completely trust JayBees. They have serviced my car many times and have even left with no bill two times! Turns out it was not an issue, and they never tried to pull anything on me. Great customer service, knowledgeable and have a really cute office cat.


-Kelly Anne M.

This is a shop that has a passion to fix the root problem, not simply pull things off and replace them until they happen upon a solution. Don't hesitate to take your car to JayBees. I had been to three shops, spent thousands of dollars on repairs, and the folks at JayBees sorted through all the potential issues and solved the problem. I have a lot of confidence in their work.


-Byron B.

If you need your car repaired use JayBees. Their staff is friendly and treated me well. When you need a repair done quickly AND fixed right the first time, they are the shop to use. I love that they have women in their shop who actually know cars and how to explain my situation to me.
