The vibration you experience can mean that the driveshaft has become imbalanced and this can lead to damage in the transmission and other components. Worn u-joints can create a thudding noise when changing gears and when suddenly increasing speeds, the noise can usually be heard from the center to rear of the vehicle. The u-joint compensates for motion and change in position, keeping the driveshaft, differential and transmission connected and spinning freely. Transmission fluid should always be topped up at the earliest interval to help prevent damage – it’s an easy way to ruin your transmission. When this lubricating fluid gets low the parts in your transmission system can grind together and cause vibrations. One of the simplest faults, and a common one would be low transmission fluid.
Repairs to your transmission can be one of the most expensive jobs you will come across, but finding the fault sooner can help to keep repairs simpler, and less expensive. Vibrating, shaking and grinding can indicate serious problems with your transmission so it’s important to get your vehicle checked sooner rather than later. Most of the time this car shaking is caused by the transmission, though it can sometimes be caused by a bent exhaust or one that’s different to the original. Anything like shaking, jolting or grinding is not normal and you should take notice. Vibration, when you shift gears, can be worrisome and even scary.
