Transmission Maintenance & Repair

“I didn’t know Lund Automotive before the time my car broke down and needed a tow. The tow truck driver recommended Lund. They did a good job at a reasonable price and did not push me to buy other services. They told me a squirrel got into the vehicle so instead of thousands of dollars of work they just charged me a couple hundred.”

Preventive Maintenance

Because your car’s transmission is an essential component for your car, it’s absolutely essential that it undergoes maintenance as recommended by the vehicle manufacturer. You can find recommended transmission maintenance in your owner’s manual or the manufacturer’s website.

Typical regular transmission maintenance items may include inspecting and adjusting the clutch pedal on manual transmission vehicles, and inspecting, topping off or flushing the transmission fluid in the transmission case for automatic and manual transmission vehicles. Many transmission repair specialists recommend checking your transmission fluid level at least twice each year.

Check your vehicle manufacturer’s recommended maintenance schedule to determine if and when these services should be performed and remember to follow recommendations specific to more severe driving conditions such as dusty environments or regularly towing or carrying heavy loads. If your stuck in slick weather conditions, it's best to call a tow truck. Trying to get your vehicle unstuck may cause transmission damage.


transmission fixes can be quite inexpensive, while others may end up costing more than the value of the car itself. Transmission repair costs can easily range from a few hundred dollars to many thousands of dollars. That’s one good reason to have your transmission inspected by a Lund Automotive Service and Repair if you suspect something may be amiss.

If you know something is wrong with your transmission, the causes can be numerous. A simple lack of transmission fluid level can leave important parts unprotected by lubricant and allow internal components to warp and gaskets or seals to fail. Modern transmissions also contain a number of electronic modules and controls that could fail and cause transmission problems.

Types of transmissions

The purpose of the transmission is to transfer the power generated by the engine to the drive axle and wheels by using different gears. A car’s engine rotates within a fixed range of speeds, generally from 600 to 7,000 revolutions per minute (rpm) for most passenger vehicles.  The vehicle’s wheels typically spin from 0 to 1,800 rpm, so the transmission uses different gears with specific ratios to match the most efficient use of engine power for the vehicle’s speed.

For instance, when starting from a full stop, your car’s engine is spinning much faster than the wheels so a lower-ratio gear that supplies higher amounts of torque is needed. When traveling at highway speeds, the wheels may be turning much faster than the engine, meaning a higher-ratio, low-torque gear is needed.

There are a few varieties of transmission types found in most modern vehicles:

Automatic transmissions: The most common type of vehicle transmission for cars built and sold in the United States, automatic transmissions automatically select the correct gear for the driving conditions. Beyond special circumstances like towing a trailer or extremely steep inclines or declines, most drivers simply have to put the vehicle’s gear selector into “D” for drive and the automatic transmission does the rest. Up until recent times, automatic transmission vehicles were typically less fuel efficient than their manual transmission counterparts.

Manual transmissions: Also known as a standard transmission or manual gearbox or simply “stick,” manual transmission vehicles are a relative minority in modern American vehicles. Manual transmissions rely on the driver to select and switch gears constantly. Manual transmissions are typically equipped with a clutch pedal that’s required for the driver to be able to switch between gears. Although manual transmission vehicles provide greatly improved fuel economy (and typically cost less than automatic transmission vehicles), the downside is the constant need for attention on the part of the driver.

Continuously variable transmissions (CVT): Typically found on lighter passenger vehicles, CVT transmissions are relatively new features in terms of the American automobile market, but they offer a special set of advantages. Although they employ a different technology than traditional automatic transmissions, they perform in the same manner in terms of driver experience. Moreover, they deliver increased fuel efficiency when compared to traditional automatic transmissions.

Signs of Transmission Problems

For most drivers, knowing if and when their vehicle has transmission problems can prove difficult. Other times, it’s obvious the vehicle is experiencing transmission trouble. If you experience any of the conditions noted below, it’s a good idea to have your vehicle inspected by Lund Automotive Service and Repair. These are signs of auto transmission problems that you can't ignore.  Delaying needed repairs or services will only make the problem worse.

1. Transmission no longer operates normally

Yes, this is an ambiguous description, but there are a wide range of indicators that you need an auto transmission repair. One of the most common yet subtle signs of needed transmission repair is when the transmission slips or hesitates; while driving, you press on the pedal and the engine revs up, but there’s no corresponding increase in speed or a hesitation between when you push the pedal and the vehicle speeds up. This can happen particularly when first starting the car on a colder morning for the first time.

If you drive a manual transmission vehicle, you may notice that moving the gear shift into or out of gears becomes extremely difficult. For automatic transmissions, the reverse gear may go out or the vehicle may slip out of gear while driving, causing the engine to roar.

2. Strange sensations

Along with improper operation, another indicator of a failing transmission can be strange vibrations or shimmying sensations when driving. If you notice a strange vibration, especially at one speed or speed range in particular, it can indicate the transmission or a transmission component needs to be repaired or replaced.

3. Warning lights

Transmissions in modern vehicles rely heavily on electronic controls and systems. If you notice a warning light flashing on your instrument cluster — especially a light that says “O/D,” which indicates the “overdrive” gear — the vehicle’s on-board diagnostic system has registered an error with the transmission. P0700 is a code that can indicate a general transmission problem.

4. Strange or new noises, especially grinding, clunking or thumping

If and when a noise accompanies your vehicles shifts, such as a clunk or thump, it’s a sure sign there’s a serious error with the transmission that requires immediate attention. If you drive a manual transmission vehicle and notice a grinding noise, it can indicate the clutch gear is no longer disengaging correctly.

5. Burning smells or strange smells

Like your car’s engine, the transmission operates at high temperatures and without the correct amount of transmission fluid to lubricate it; the transmission can overheat and fail. You may notice a strange chemical or burning smell when the car is operating.

6. Fluid leaks, puddles beneath the car

Transmission fluid is absolutely essential for proper transmission operation. If you notice brown, red or pink puddles or leaks under your vehicle, it could be a transmission leak from a faulty gasket or seal. Knowing when to change transmission fluid helps avoid costly repairs. Experts say to flush the fluid at 60,000 to 90,000 miles and again at 120,000 to 150,000 miles, or when the fluid changes from a pink to a dark red or brown. Auto transmission fluid exchange has been known to correct shifting problems and delayed engagements. If you didn't notice a leak, but a auto repair shop says you need a fluid change, ask them to show you and explain why.
