Many modern cars don’t have a transmission fluid dipstick, so the only person who can check it is a pro.īut if your car does have a dipstick, here are a few things to keep in mind. The first thing to determine is whether you’re able to check the fluid at all. In a practical sense, the most important reason to perform preventive maintenance on your transmission comes down to dollars and cents: getting a transmission fluid flush might cost you a few hundred dollars, but a new transmission will cost thousands. Unlike other fluids, however, transmission fluid doesn’t just lubricate the transmission parts, it also acts as hydraulic fluid, helping keep the transmission cooler and helping with shifts. Stop-and-go driving, towing or other high-stress conditions can shorten its life even further. Like any other fluid such as engine oil, transmission fluid becomes less effective over time. The top reason to change it is to keep your transmission operating at its best.

Unless there’s a leak or a problem, some newer transmissions are designed to never need a fluid change.īut let’s say your car does need a transmission fluid flush as part of preventive maintenance. However, it may take up to 300 miles (480 km) for the new fluid to fully saturate the clutch plates.Actually, the first question is “Do I need to change my transmission fluid at all?” For the answer, consult your chevrolet Owner’s Manual. A 2018 Chevy Silverado transmission flush also uses about 10 quarts of fluid to completely clean and flush out the system. Adjust the fluid level following the instructions in the appropriate Service Information.Īfter replacing the fluid, the shudder should be noticeably improved within 100 miles (160 km). Reinstall the cooler return line and add two quarts of CVT fluid to the transmission. If necessary, run the engine again, but for no more than 20 seconds. It will take 3–4 quarts (2.8–3.8 L) to flush the torque converter and discharge clean fluid from the return line. The flow rate should be approximately one quart per 10 seconds. Run the engine for 30 seconds and then check the amount of fluid in the container. The cooler return line connects at the lower port at the transmission. Filled with five quarts, the transmission will be over full.ĭisconnect only the transmission cooler return line from the transmission and route it into a suitable container.

Do not replace the transmission if metal chips cannot be felt in the magnetic sludge. 13) If the magnets show only normal magnetic sludge, reinstall the pan using a new gasket, if needed. 12) It is normal to have some metallic build-up on the magnets. An abnormal amount of debris will be noticeable. Start the procedure by first removing the fluid pan and inspecting the magnets for metal debris. TIP: It’s normal for the transmission to remain in high range under medium to hard braking and may only make the high/low range shift on acceleration after the braking maneuver.ĭrain and replace the fluid to reduce the shudder condition. The shudder is a momentary condition and may only occur under certain rates of braking and accelerating.ĭegradation of the CVT transmission fluid may alter the friction characteristics of the transmission and lead to shudder concerns during a shift from high or low range. 11) may have a short duration shudder on launch from a stop or on acceleration from a low speed, such as when turning a corner. Some Jatco CVTs (continuously variable-ratio automatic transmissions) (RPOs M4M, MR8) available in the 2014-2019 Spark (Fig.
