    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 Expert 4WD & Auto in Loveland, CO. 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 970-278-9119 to talk to the mechanics of Expert 4WD & Auto 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 970-278-9119 to talk to the mechanics of Expert 4WD & Auto 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 970-278-9119 or visit Expert 4WD & Auto 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 Expert 4WD & Auto'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 Expert 4WD & Auto 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 970-278-9119 to talk to the mechanics of Expert 4WD & Auto about your cylinder block problems.

    I am fairly selective in giving out positive reviews online but Larry and his team have earned it for repeated positive experiences in fixing my vehicles. All I can say is that this team does everything in its power to make sure you are taken care of in an industry know for the opposite. What else is there to say. They deserve your business.


  • -Adam W.

    Quoted me considerably less than other shops (30-40% less) for a clutch replacement. The turnaround was wasn't the quickest, but were willing work around my schedule and meet me on a day they were closed to get my car back before a holiday weekend. Would highly recommend; great experience working with this shop.

  • -Erik N.

    My wife and I took our honeymoon in Estes Park, CO and our transmission went out in our suv. We took the truck to Expert 4wd in Loveland, CO and after talking with Joe I knew our truck was in good hands. The transmission we needed was not going to get there before we were heading back so Joe called enterprise and gave us a ride to get a rented car, We enjoyed the rest of our honeymoon and took the rental back to our home state. After the repairs were complete I flew to Denver and to my surprise Joe was willing to pick me up at the airport on a Sat to pick up the suv. The amount of customer service, hospitality and honesty was amazing, I would highly recommend these guys to work on your vehicle. Thank you Joe!!!! I can not say that enough for everything you did for my wife and I
