A skipping issue while driving in overdrive can have several possible causes, and it may not necessarily be related to a timing belt or transmission problem. Here are some potential reasons for the issue you are experiencing:
1. Low Transmission Fluid: Check the fluid levels in your transmission and make sure they are within the recommended range. Low transmission fluid can cause the transmission to slip and skip gears, especially in higher gears like overdrive.
2. Faulty Transmission Solenoid: A faulty solenoid within the transmission can interfere with gear shifting and cause the transmission to skip. Solenoids are responsible for controlling the flow of transmission fluid and engaging different gears.
3. Sensor Issues: Faulty sensors related to the transmission or engine can provide incorrect information to the vehicle's computer, causing shifting problems. These sensors might include the vehicle speed sensor, input/output speed sensors, or even sensors related to the engine management system.
4. Torque Converter: The torque converter, which connects the engine to the transmission, can sometimes cause skipping issues if it is damaged or malfunctioning.
5. Transmission Mechanical Issues: If the problem persists even after addressing potential fluid-related or electrical issues, it's possible that there may be internal mechanical problems within the transmission. These could include worn gears, damaged clutches or bands, or other mechanical issues.
Timing Belt Issues: While a skipping sensation while driving can sometimes be associated with a worn or damaged timing belt, it's important to note that timing belt problems usually result in more severe symptoms, such as the engine stalling or misfiring.
It's recommended that you take your vehicle to a qualified mechanic or transmission specialist for a proper diagnosis. They can inspect the vehicle, conduct tests, and provide an accurate assessment of the issue you're experiencing.
