Some signs of low transmission fluid are slipping or jerking motions as the gears shift, dragging of the vehicle as it picks up speed, increase in the temperature of the transmission and failure of the transmission to engage. Low transmission fluid levels are the most common problem associated with transmissions.
Transmission fluid lubricates, cools and powers a vehicle's transmission. Over time, wear and tear can cause the seals, gaskets and valves of the transmission to leak resulting in low levels of transmission fluid. Faulty parts should be replaced as these leaks are identified. Fluid levels should be regularly checked and maintained according to vehicle specifications to ensure proper operation of the transmission.
