Knowing the symptoms of transmission trouble is half the battle. Keep an eye (and ear) out for these telltale signs in your 2017 GMC Savana 2500. Pay close attention to how your vehicle behaves, especially during gear changes. One of the first signs of transmission trouble is often a noticeable change in shifting patterns. This could include delayed shifts, where the transmission takes longer than usual to engage the next gear, or erratic shifts, where the transmission seems to jump between gears without a clear pattern. Another common symptom is slipping gears, which, as mentioned earlier, can cause the engine to rev up without a corresponding increase in speed.

Unusual noises coming from the transmission can also be a warning sign. These noises may include whining, clunking, or humming sounds that are not typically present during normal operation. It's important to note when these noises occur, such as during specific gear changes or at certain speeds, as this information can help a mechanic diagnose the problem more accurately. Additionally, be aware of any changes in the way your vehicle feels when shifting gears. This could include a sudden jolt or shudder, or a feeling of hesitation or resistance. Finally, check for any leaks under your vehicle, particularly near the transmission. Transmission fluid is typically red or brown in color and has a distinct odor, so if you notice any fluid leaks that match this description, it's important to have them investigated promptly.

Diagnosing Transmission Issues in Your Savana 2500

So, you've noticed some transmission quirks in your Savana 2500? Time to play detective! A proper diagnosis is key to fixing the right problem. The first step in diagnosing transmission issues is to perform a thorough inspection of the transmission itself. This includes checking the fluid level and condition, inspecting for any signs of leaks or damage, and listening for any unusual noises. If the fluid level is low, it's important to add the correct type of transmission fluid to the proper level. However, if the fluid is dark, dirty, or smells burnt, it may indicate that the transmission needs to be serviced or repaired.

In addition to a visual inspection, a mechanic may also use diagnostic tools to gather more information about the transmission's performance. This could include using a scan tool to check for any diagnostic trouble codes (DTCs) stored in the vehicle's computer. These codes can provide valuable clues about the nature and location of the problem. A mechanic may also perform a transmission fluid pressure test to check the pressure of the fluid as it flows through the transmission. Low pressure can indicate a problem with the transmission pump or valve body, while high pressure can indicate a blockage or restriction in the system. Finally, in some cases, it may be necessary to remove the transmission pan to inspect the internal components for wear or damage. This can provide a more detailed view of the transmission's condition and help identify any underlying problems.
