Additional Notes

  • The Renault 21 1.7 TL-GTL, TS-GTS-TSE (1986-1994) carries an automatic transmission fluid capacity of 3.5 liters, placing it between the smaller transaxle unit and the larger transmission assemblies found in other 21 variants.
  • The 21 2.0 RX, GTX (1989-1992) and the 21 2.2 (1986-1995) share an identical automatic transmission fluid capacity of 4 liters, representing the highest fill volume across all four configurations listed.
  • The 21 2.0 RX, TXE (1986-1989) is noted as a transaxle rather than a standalone transmission, and its automatic fluid capacity of 2.5 liters is the lowest among all listed configurations, consistent with the more compact integrated drivetrain layout a transaxle represents.
  • All four configurations share a uniform check interval of 10,000 km or 12 months under normal use conditions, indicating a consistent monitoring schedule regardless of engine displacement or transmission type.
  • The fluid change interval of 60,000 km or 36 months applies uniformly across all listed configurations under normal use, meaning the longest permissible service gap before a full fluid replacement is three years or 60,000 km, whichever comes first.
  • The 21 2.0 RX, TXE (1986-1989) and the 21 2.0 RX, GTX (1989-1992) represent successive model year ranges for 2.0-liter RX variants, yet the transaxle unit of the earlier 1986-1989 period holds 1.5 liters less fluid than the conventional automatic transmission of the 1989-1992 period.
