ATF
 

Description

PSO Automatic Transmission Fluid is blended with high quality base oils and selective additive system to meet General Motor’s transmission performance category Type-A Suffix-A. The fluid is suitable for use in transmission systems of off-road vehicles and power steering where TASA specification is recommended.
 

Applications

  • PSO ATF automatic transmission fluid is suitable for transmission system of heavy duty truck and power steering where manufacturers specify an oil meeting GM Type-A/Suffix-A specifications.
     

Benefits

  • Protects gear components from deposit and corrosion and facilitates easy gear shifting.
  • Good oxidation and thermal stability, high viscosity index and low pour point enhance the performance of transmission system for longer period of time.
  • It also performs as hydraulic oil where suitable.
