What issue can low fluid levels in the transmission cause?

Low fluid levels in the transmission can lead to slipping or delays in shifting gears because the transmission fluid serves several critical functions. It lubricates the moving parts within the transmission, ensuring smooth operation. Additionally, transmission fluid helps to create hydraulic pressure necessary for the engagement of gears. When fluid levels are low, there isn't enough hydraulic pressure to facilitate proper gear engagement.

As a result, the vehicle may experience symptoms like slipping—where the engine revs higher without a corresponding increase in vehicle speed—or delayed engagement when trying to shift gears. This can lead to poor performance, increased wear and tear on the transmission components, and ultimately, potential transmission failure if not addressed promptly. It's vital for the transmission fluid to be maintained at the optimal level to ensure effective shifting and overall transmission health.
