If you notice any of these symptoms, it is likely that your transmission bearings are bad and may need to be replaced.

In most cases, a transmission bearing can be replaced. However, this will require the removal of the transmission. It is generally more cost-effective to replace a bearing rather than the entire transmission. The cost of the replacement will depend on which bearing needs to be replaced, as there are several bearings inside the transmission.

Transmission bearing failure can be caused by various factors. Excessive wear of the bearing is often the result of long and regular journeys with maximum load and without proper monitoring of the transmission fluid level. It is important to maintain the transmission and ensure that the fluid level is at the appropriate level to prevent bearing failure.
