Additional Notes

  • Across all configurations of the Audi 80, 80/82 (B1), the automatic transmission holds 6 liters at dry fill, meaning a complete overhaul or initial build-up of the transmission requires the full 6-liter volume to bring the unit to its correct operating level.
  • The service fill capacity of 3 liters applies to all listed configurations, representing roughly half the dry fill volume and reflecting the amount of fluid retained in the torque converter and passages during a routine drain-and-refill service.
  • For the 80 1.5 (55 kW) in both the 1972-1976 and 1976-1978 model ranges, the 6-liter dry fill is specifically noted as applying with a towing package, indicating the towing package variant carries additional fluid volume requirements compared to a standard dry fill scenario.
  • The 80 1.5 (63 kW) and 80 1.6 (63 kW) configurations list the 6-liter dry fill without a towing package qualifier, distinguishing the capacity notation from the 55 kW variants where the towing package condition is explicitly tied to that figure.
  • Under normal use conditions, all listed configurations share a 45,000 km change interval, while severe use conditions reduce the change interval to 30,000 km across every configuration, a 33 percent reduction in service life between the two use categories.
  • The fluid check interval for the 80 1.5 (55 kW) variants remains at 15,000 km regardless of whether normal or severe use conditions apply, meaning the check frequency does not tighten under more demanding operating conditions for those configurations.
  • For the 80 1.5 (63 kW) and 80 1.6 (63 kW) variants, the check interval shortens from 15,000 km under normal use to 10,000 km under severe use, a reduction that does not appear in the 55 kW specifications.
  • The 1976-1978 model range introduces the 82 body designation alongside the 80, yet the automatic transmission fluid capacities and service intervals for the 1.5 (55 kW) and 1.6 (63 kW) pairings in that period are identical to their respective 1972-1976 predecessors.
