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 Don's Complete 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 Don's Complete Auto Service at 407-847-3427 to schedule an appointment. Proudly remanufactured in the U.S.A.

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 407-847-3427 to talk to the mechanics of Don's Complete Auto Service about your cylinder block problems.

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 Don's Complete Auto Service's cylinder head repair and reconditioning specialists today.

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 Don's Complete Auto Service to help your diesel engine last a long time.

Engine Maintenance
Any car part manufacturer will tell you that preventive maintenance is critical to the part's lifespan. Like other auto parts, car engines aren't built to last forever. However, you can increase the engine's lifespan by performing regular preventive maintenance. The easiest way to maintain peak performance and fuel economy is to provide regular engine maintenance for your vehicle. To have your engine maintained by experts, visit Don's Complete Auto Service.

Engine Repair

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. When this happens, do not sit and stress over it. Take action. Take the vehicle to a mechanic for an engine replacement. Bring it to Don's Complete Auto Service. Visit us at 508 E Vine St for quality engine replacement services.

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 Don's Complete Auto Service 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 407-847-3427 or visit Don's Complete Auto Service today - we are transmission experts.

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 Don's Complete Auto Service.

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 407-847-3427 to talk to the mechanics of Don's Complete Auto Service today.

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 Don's Complete Auto Service in Kissimmee, FL. Our experienced service technicians can help you make the best decision for your vehicle and your wallet.

Hands down the best mechanic you will find in the area! When I moved here four years ago, my Honda had just approached her midlife crisis and required numerous repairs. Finding a reliable mechanic is no easy task, and I've had to learn it the hard way. It wasn't until I discovered Don and his team that I could finally feel at ease and with confidence, knowing that my baby is in good hands every time she acts up. Don's Complete Auto Care is my go-to for everything auto related, from routine maintenance to major repairs, they had been there for me, above and beyond, all at a fair price. Thanks guys Cannot recommend highly enough!

Neal and Luis I can't thank you enough. These guys have been so helpful. Im from out of state and my son has my car and living in Florida. He was involved in an accident and had issues with the headlights not working. After spending alot at firestone and still not figuring it out, I was very nervous on who to try next. It didn't help dealing with this from out of state. Neal and Luis figured it out and found out Firestone messed up. Neal and Luis saved alot of anxiety and put my mind at ease. They will be our go to guys as long as my son is down there. I 100% recommend this place. Thanks guys.
