19-25 GM 8L45/8L80/8L90 Heavy-Duty Cast Aluminum Transmission Pan-Raw Pacific Performance Engineering LB7 Duramax Agricultural and ConstructionThe GM 8 speed transmission has faced several issues, including excessive vibration and harsh or delayed shifts. 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 low due to
