Low Transmission Fluid Level: Check the transmission fluid level and condition. If the fluid level is low, add the recommended fluid and check for any leaks.
Faulty Transmission Solenoids: Solenoids are responsible for controlling the flow of transmission fluid, which engages and disengages the gears. If a solenoid is faulty, it can cause shifting problems.
Worn-Out Clutch Packs: Clutch packs are responsible for transferring power from the engine to the transmission. Over time, clutch packs can wear out and cause slipping, leading to delayed or harsh shifting.
Faulty Torque Converter: The torque converter is responsible for transferring power from the engine to the transmission. If the torque converter is faulty, it can cause vibration during acceleration.
Mechanical Issues within the Transmission: There could be internal mechanical issues within the transmission, such as worn gears or damaged components.
It's recommended that you take your car to a qualified mechanic for proper diagnosis and repair of the transmission problems. They will be able to identify the exact cause and perform the necessary repairs or replacements.
Please note that driving with a faulty transmission can cause further damage and safety risks, so it's important to address the issue promptly.
