Additional Notes

  • The PAZ 3237-01, 3237-03, and 3237-09 variants share an automatic transmission fluid capacity of 14 liters, applying equally to both preferred and acceptable fluid grades.
  • The 3237-05 carries a notably larger automatic transmission fluid capacity of 17 liters, which is 3 liters more than the figure listed for the 3237-01, 3237-03, and 3237-09 configurations.
  • For the 3237-05 under normal use conditions, the automatic transmission fluid change interval is set at 120,000 km, 36 months, or 3,000 hours, whichever comes first.
  • The 3,000-hour threshold in the 3237-05 service interval reflects an operating-hours metric, which is typically applied to vehicles used in continuous or commercial duty cycles where mileage alone does not capture actual drivetrain load.
  • The 36-month time-based interval for the 3237-05 means fluid replacement is due after three years regardless of whether the distance or hour limits have been reached, making calendar time an independent trigger.
  • The 3237-05 variant entered the specification set starting from 2013, one year after the 3237-01, 3237-03, and 3237-09 configurations, which are listed from 2012.
