Many of these problems can stem from low or inconsistent transmission fluid pressures. Transmission fluid pressure is closely tied to fluid temperature: as temperature rises, fluid viscosity decreases, requiring the oil pump to work harder to maintain the desired pressure. However, if the transmission fluid viscosity becomes too
