What does "transmission slip" refer to?

"Transmission slip" refers to the condition where the engine revs higher than the vehicle speed, indicating a loss of power transfer. This phenomenon usually occurs due to various issues within the transmission, such as worn clutch plates or low transmission fluid levels. When slip happens, the engine may continue to accelerate, but the vehicle does not gain corresponding speed, which can lead to inefficient vehicle operation and may signal a need for maintenance or repairs. Understanding this concept is essential for diagnosing transmission problems effectively, as it highlights the importance of the connection between the engine and the wheels in a vehicle.
