Additional Notes

  • The Pontiac Trans Sport 3.8 V6 automatic transaxle holds 5.7 liters of fluid, a figure that reflects a service fill level rather than a full overhaul or dry fill capacity, which would typically be higher due to fluid retained in the torque converter and passages.
  • The 5.7-liter service fill capacity applies uniformly across the 1991-1995 model years for the 3.8 V6 configuration, with no variation listed between those years.
  • The fluid check interval is set at 15,000 km or 12 months, whichever comes first, under normal use conditions, meaning the transaxle is not expected to require topping off more frequently under everyday driving circumstances.
  • The fluid change interval under normal use is 60,000 km or 48 months, placing the drain-and-fill cycle at roughly four years of standard operation, which is consistent with the longer service expectations of automatic transaxle fluid from that era.
  • The check interval of 15,000 km sits at one-quarter of the 60,000 km change interval, meaning a fluid level inspection is expected approximately four times between each scheduled fluid change under normal use conditions.
