Take a few minutes to read this article as you wait for a tow truck. Limp mode allows you to reach up to 40 mph speeds. Limp mode reduces engine output, limits the RPMs and speed, and prevents the transmission from shifting gears. The main function of limp mode is to prevent further damage to the engine or transmission. When the On-Board Diagnostic (OBD) system detects a critical problem, cars go into limp mode. A restriction in the transmission fluid system can also cause the transmission to overheat and may cause the gears to bind or stick. Low transmission fluid levels can cause the transmission to overheat and may cause the gears to bind or stick, while a malfunctioning transmission cooler can cause the transmission fluid to overheat and may cause the transmission to enter into limp mode. Other possible causes of a transmission stuck in gear include low transmission fluid levels, a malfunctioning transmission cooler, or a restriction in the transmission fluid system. These issues can cause the transmission to become stuck in a particular gear, as the gears may not be able to engage properly or disengage.

Worn or damaged gears, worn or damaged synchronizers, or a malfunctioning clutch can cause this. In this case, the TCM may not be able to communicate properly with the transmission and may not be able to shift gears properly.Īnother common cause of a transmission stuck in gear is a mechanical issue within the transmission itself. The TCM is responsible for controlling the transmission, and it may malfunction due to a software issue, a wiring problem, or a hardware failure.

One of the most common causes of a transmission stuck in gear is a malfunctioning transmission control module (TCM). When the TCM detects a problem with the transmission, it may enter into a fail-safe mode, also known as limp mode, to protect the transmission from further damage. The TCM is a computer that controls the transmission and receives input from various sensors to determine when to shift gears. A transmission stuck in gear, also known as limp mode, is a condition where the transmission cannot shift out of a particular gear, usually a low gear, and is typically caused by an issue with the transmission control module (TCM) or the transmission itself.
