Low transmission fluid level: Insufficient transmission fluid can cause the transmission to slip and not engage properly. Check the transmission fluid level and top it up if necessary.
Transmission filter issues: A clogged or dirty transmission filter can restrict fluid flow, leading to transmission problems. Regular transmission maintenance, including filter replacement, is recommended.
Solenoid issues: Solenoids control the flow of transmission fluid and regulate gear shifts. A faulty solenoid can prevent the transmission from shifting properly.
Mechanical problems: Internal mechanical issues within the transmission such as worn gears, broken bands, or damaged clutches can cause the transmission not to engage in gear.
Faulty sensors or wiring: Sensors provide information to the transmission control module (TCM) about gear selection and other parameters. Faulty sensors or wiring can disrupt the communication between the TCM and the transmission, causing shifting issues.
TCM issues: The transmission control module (TCM) is responsible for managing the transmission's operation. A malfunctioning TCM can affect the transmission's ability to shift gears.
Other electrical problems: Electrical issues such as loose or corroded wiring connections or problems with the ignition switch or shifter assembly can prevent the transmission from engaging in gear.
