• Slipping Gears – Occurs when the transmission unexpectedly changes gears, often due to worn clutches or low transmission fluid levels.
• Delayed Shifting – A noticeable lag when shifting gears, typically caused by faulty solenoids or low hydraulic pressure.
• Transmission Overheating – Excessive heat can damage components, often resulting from low fluid levels or a failing torque converter.
• Fluid Leaks – Leaks can lead to low fluid levels, often caused by damaged seals or gaskets within the transmission.
• Harsh Shifting – Rough or jerky gear changes, usually due to worn clutches or incorrect transmission fluid type.
• Torque Converter Issues – Problems with the torque converter can cause shuddering or slipping, often due to worn bearings or seals.
• Check Engine Light – A warning light may indicate transmission issues, often related to sensor or electronic control module faults.
• Unusual Noises – Grinding or whining sounds can indicate internal damage, often due to worn gears or bearings.
