- Low transmission fluid: Check the transmission fluid level; low fluid can cause slipping and difficulty shifting gears.
- Faulty transmission: The transmission may need to be repaired or replaced if it is damaged or worn out.
- Slipping transmission: Transmission slipping occurs when the transmission is unable to properly transfer power from the engine to the wheels. This can be caused by low transmission fluid, worn clutches or bands, or a faulty valve body.
- Clogged transmission filter: A clogged transmission filter can restrict fluid flow and cause the transmission to overheat, leading to slipping or shifting problems.
- Vacuum leak: A vacuum leak can cause the transmission to shift erratically or slip out of gear.
- Malfunctioning sensors: Faulty sensors, such as the speed sensor or the throttle position sensor, can send incorrect signals to the transmission control module, causing shifting problems.
- Computer issue: The transmission control module (TCM), which is the computer that controls the transmission, may be damaged or need to be reprogrammed.
