Our competitively priced truck services include:


A clutch is an element of the drive train, in the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). One shaft is usually attached to the engine (the driving member) while the other (the driven member) is attached to the axel to provide power for turning the wheels.

The clutch is located between the gearbox and the engine. During a gear change, disengaging is required of the two shafts mentioned above, and the clutch facilitates this. Clutches need periodic servicing and replacing. When it comes to clutch repairs and replacements, you can count on Vernell’s Interstate Service in Marion, IL. We have expert mechanics that will ensure all your truck’s clutch issues are addressed.


The differential is another element of your truck’s drive train. The differential lets your truck make maneuvers with ease. The differential should be serviced on a regular basis. Your truck requires periodic differential repairs and replacement. At Vernell’s Interstate Service of Marion, IL, we offer differential maintenance services for trucks.


A driveline is made up of all the parts of the powertrain (the main components that generate power and drive your truck) excluding the transmission and engine. The driveline set-up can change depending on whether the vehicle is rear-wheel, front-wheel, or four-wheel drive.

With time, moisture, pressure, heat and load, the gear oil starts to breakdown leading to lubrication failure and worn out gears. This will result in a noisy engine and poor truck performance. To solve driveline problems, you need to have the worn-out lubricant and engine parts replaced. To have this done by experts, call us at (618) 993-6250 or visit Vernell’s Interstate Service of Marion, IL today. We will ensure that you experience smoother gear shifting.


A truck’s transmission adjusts the production of mechanical power from the engine to drive the wheels. The main purpose is to reduce the number of turns made by the crankshaft by use of interlocking gears. The common types of transmissions include manual transmission, automatic transmission, semi-automatic transmission, direct shift gearbox (DSG), TipTronic gearbox, and continuous variable transmission (CVT).

With time, a truck’s transmission wears out and starts developing problems. Transmission problems are known to cause mechanical breakdowns. When this happens, you need to have the transmission repaired, rebuilt, or replaced. For everything from transmission rebuilding to transmission repair and transmission replacement, trust Vernell’s Interstate Service. Call us at (618) 993-6250 or visit us today.
