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.

The easiest way to maintain peak performance and fuel economy is to provide regular transmission maintenance for your vehicle.

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 Slone's Automotive Service in Moraine, OH. 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 937-294-6653 to talk to the mechanics of Slone's Automotive Service 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 937-294-6653 to talk to the mechanics of Slone's Automotive 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 937-294-6653 or visit Slone's Automotive 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 Slone's Automotive 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 Slone's Automotive 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 937-294-6653 to talk to the mechanics of Slone's Automotive 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 Slone's Automotive 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 Slone's Automotive Service at 937-294-6653 to schedule an appointment. Proudly remanufactured in the U.S.A.


What Our Customers Are Saying

Nice, honest guy that did great work. Just as I was told by a friend. 5 stars!

Very experienced with diagnosing difficult problems. Very fair pricing and honest. Diagnosed our family's Suzuki drive belt issue that another shop couldn't figure out. Properly troubleshooted a backup light issue on our Tahoe. Highly recommended!

This has to be the best auto repair shop on earth. These guys are friendly, do great work, and they charge reasonable prices. I highly recommend them.


-K. W.

Fair and friendy. Has handled my company business for years...and for years to come.


-Alan Z.

Slone's Automotive is one of two mechanics in Dayton that I trust without a doubt to do great service at a fair price. I have taken my car here twice for service and have been blown away every single time with their service. I know a lot about cars and can tell immediately when someone is trying to pull a fast one. This has never been the case with Slone's. I walk in with a price estimate in my head, and they match it every time. Slone's is the best small business in Dayton, IMO.


-R. P.

Can't say enough great things about Mick Slone and crew! Business has been around for a long time, I've used them since the 80s, and they did a great job fixing my Truck a few months ago. Always reasonable prices and up front about telling you what's wrong with your car. Total auto care that's just about as good as it gets.


-Gary R.

Slone's have been my "go to guys" since I started driving. Some 30 years later, I would not go anywhere else. I now live over an hour away, but well worth the drive for this level of service from someone I can trust.


-Thomas L.

Really helpful staff, including clean & new U-Haul trucks. A multi-generation family business.
