Frequently Asked Questions (FAQs)

1. Can I drive with a bad transmission input shaft bearing?

It is not recommended to drive with a bad transmission input shaft bearing. Continuing to drive with a faulty bearing can lead to further damage as the metal particles from the worn bearing can contaminate other bearings in the transmission. It is best to replace the input bearings and input shaft seal as soon as possible to avoid more extensive repairs.

2. How do I know if my input shaft bearing is bad?

There are several signs that indicate a bad input shaft bearing in a transmission. These include strange noises in neutral, persistent noises from the gears, and sudden gear slips. If you experience any of these symptoms, it is likely that the input shaft bearing is faulty and requires attention.

3. What causes an input shaft bearing to fail?

The primary cause of input shaft bearing and seal failures is misalignment between the drive motor and the gearbox. It is crucial to ensure proper alignment to prevent damage to the input shaft bearing. Taking the time to align the components correctly can help avoid premature failure of the input shaft bearing.

4. What happens when a transmission bearing goes out?

When a transmission bearing fails, it can seize, leading to excessive wear on the pressure plate's fingers. The throw-out bearing, which is responsible for engaging and disengaging the clutch, may need to be replaced when the clutch is replaced. Regular maintenance of the throw-out bearing is not required, but replacement is necessary when clutch replacement becomes necessary.

5. What are the symptoms of automatic transmission bearings?

Defective automatic transmission bearings can cause loud gear shift sounds. These bearings may produce constant noise from the engine during gear shifting, which can put additional pressure on the transmission and load on the engine. If you notice such symptoms, it is advisable to have the automatic transmission bearings inspected and replaced if necessary.

6. What is the most common cause of worn input and output shaft bearings?

The most common cause of worn input and output shaft bearings is lubrication failure. Improper lubrication, such as insufficient lubrication, using improper lubricants, or subjecting the bearings to excessive temperatures that degrade the lubricant, can lead to up to 80% of bearing failures. It is essential to ensure proper lubrication to prevent premature wear and failure of the input and output shaft bearings.

7. How much does it cost to replace a transmission bearing?

The cost of replacing a transmission bearing can vary depending on various factors. On average, it can range from $330 to $820. The cost includes labor, which typically takes around four to six hours to complete. Labor prices can vary between $75 and $120 per hour. It is recommended to consult with a qualified mechanic for an accurate estimate based on your specific situation.

8. What are the first signs of bearing failure?

The first signs of bearing failure include issues related to lubrication, such as using the wrong type or quantity of lubricant. Other signs include contamination, vibration, excessive noise, and increased operating temperature. If you notice any of these signs, it is important to investigate and address the bearing issue promptly to prevent further damage and potential failure.
