What Causes the Abnormal Noise When Shifting Gears in a Grand Cherokee?
2 Answers
Grand Cherokee shifting gear abnormal noise reasons are as follows: 1. Normal ABS activation: The ABS working process is actually a cycle of locking-releasing-locking-releasing, keeping the vehicle in a state of near-lock rolling. When you brake hard and trigger the ABS, it will produce a clunking sound, which is normal. In this case, just press the brake pedal firmly to the end. 2. Automatic transmission vehicle makes a "clunk" sound when braking: If you hear a "clunk" sound between the transmission and the gear lever when pressing the brake pedal, the main reason for this sound may be the electronic linkage between the brake system and the automatic transmission. Pressing the brake activates the transmission solenoid valve, which produces a "clunk" sound. At this time, you need to press the gear lever lock button to shift gears, which serves as a safety reminder.
I've been driving my Grand Cherokee for over five years, and last year I also encountered the issue of clunking sounds when shifting gears. At first, I thought it was normal and didn't pay much attention, but the noise gradually got louder. When I took it to the repair shop, they found that the transmission fluid had turned black, reducing its lubrication effectiveness and causing gear friction noises. After replacing the fluid, the situation improved significantly, but the mechanic mentioned that the clutch release bearing also showed signs of wear and could damage the transmission if not replaced promptly. Another time, the issue was a loose universal joint on the driveshaft, which caused noticeable shaking in the chassis during low-speed gear shifts. Parts for the Grand Cherokee can be quite expensive, so it's really important to check any unusual noises early—don't wait until you have to repair the transmission like I did, or you'll end up paying a lot more.
