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 Walt's Service Inc. in Columbia, MO. 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 573-449-4171 to talk to the mechanics of Walt's Service Inc. 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 573-449-4171 to talk to the mechanics of Walt's Service Inc. 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 573-449-4171 or visit Walt's Service Inc. 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 Walt's Service Inc. 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 Walt's Service Inc.'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 573-449-4171 to talk to the mechanics of Walt's Service Inc. 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 Walt's Service Inc. can drop in a completely remanufactured JASPER gas or diesel engine, transmission or differential and get you back on the road again quickly! Call Walt's Service Inc. at 573-449-4171 to schedule an appointment. Proudly remanufactured in the U.S.A.


What Our Customers Are Saying

Was driving from NY to LA when my Bus started dying on the highway. Lookup the nearest VW mechanic and come here. Walt is great! He took a look at my Bus, even though it was late and he was busy-and told me the last guy who rebuilt the engine screwed up. I trusted Walt to rebuild the engine, and he did it cheaper and quicker than the first mechanic, and much better! I now have 10-15mph higher top speed and it runs a lot smoother. Driving from MO to LA I went from losing 1qt/1000 miles to losing no oil! Superb job, honest guy, nobody knows more about air-cooled VWs than he.


-Brandon C.

My daughter, a MU student, and her used 2007 high mileage Audi A4 broke down, the car was towed to Walt's. Walt called me the next day and went over his diagnostics and recommendations. He only recommended what needed to be done and did not recommend useless/costly repairs. When the car was complete, he called me with the final bill which was totally reasonable. He was timely and great to work with! I highly recommend this repair shop, it is so hard to find honest and qualified technicians and mechanics these days and Walt is truly one of the best I have ever worked with. I will definitely be back, thank you so much!


-Robert H.

I have an old (2001) high mileage (155k+) VW Golf, and I only take it to Walt's. The staff is friendly, honest, fair, and fairly quick with repairs. They give you options and explain the pros and cons of optional repairs. They keep my old Golf running well, with fair costs for repairs. I would (and have) recommended to anyone with a VW or similar German car.


-Noel B.

I had my MINI Cooper serviced here. These guys are great. They showed me everything about my car (as I know nothing about cars). The Baron MINI in Kansas City told me I needed new front and back brakes and rotors. After showing me how much brake pad I had left on the back brakes, the guy at Walt's said "that's nuts and these should last at least another year". They also did quality work and cost a couple hundred bucks less! I am very pleased!


-Grant V.

I would not take my car anywhere else. They are honest, friendly and work with you to make the best/most cost effective repair solutions.


-Shannon W.

Great people and service. They went above and beyond in order to help me resolve a problem with my 2011 Audi S5. Definitely plan on going back.


-Austin B.

Staff is very friendly and helpful. Also very knowledgeable.

-Sammi T.

Friendly honest shop. Best place to get European cars worked on in Columbia.


-Scott W.

I have seen the work they do on Porsche 911's, many times, first hand. They are friendly and helpful. Very knowledgeable staff. If they tell you something, listen to them. The best Porsche service in MO.


-Three Hour Tour Official

To say that Walt is honest would be the understatement of the century! As a female, I'm always nervous about being taken advantage of. And with a 2005 BMW Z4, sometimes work needs to be done!Thank you Walt. You have created a loyal customer.


-Jami C.

Would not take my Passat Wagon anywhere else! They have always finished my repairs in a very timely manner and at the most reasonable rates. They are truly professional in all areas of service. Thanks again, guys, for taking care of me and my vehicle.


-Pamela W.

This place is trustworthy, dependable and communicates everything to you very well. I graduated from MU and now drive all the way from Saint Louis so that I can get my car serviced at this location. No other service center can compare to these guys.


-Ryan P.

A good shop with experienced techs and good labor rate compared to larger places. They know what they are doing!


-Anthony V.

Walt's shop has worked on three of my vehicles during the past couple of years. Results were excellent, and I found their prices competitive with other shops in the area. Everyone there is helpful and courteous. My vehicles include domestic brand trucks and SUV's so be aware Walt's work is not limited to just imported models.


-John M.

This shop has been consistently top notch for service, honesty, and pricing. Although the specialize in foreign cars, I also take my other vehicles to them, as well. I highly recommend them.
