Additional Notes

  • The London Taxi Company TX automatic transmission fluid capacity splits clearly between two generations. The TXI and TXII carry 7.9 liters, while all TX4 variants across every emission standard hold 9 liters, representing a notable increase of just over 1 liter between the older and newer platform designs.
  • The TXI (1997-2002) and TXII (2002-2006) share identical service intervals under normal use conditions: a fluid level check at 15,000 km and a full fluid change at 30,000 km. Intervals expressed in kilometers rather than miles reflect the measurement standard applied to those earlier models.
  • The TX4 Euro 4 (2006-2012) is the only TX4 variant with a specified fluid check interval, set at 10,000 miles under normal use. The change interval for the Euro 4 is 40,000 miles, the longest drain interval of any TX4 configuration in the specifications.
  • TX4 Euro 5 (2012-2015) and TX4 2.4 (2013-2016) both carry a 36,000-mile change interval under normal use conditions, with no separate check interval listed for either. The overlapping production years of these two variants indicate they were sold concurrently during 2013-2015.
  • The TX4 Euro 6 (2015-2017) has the shortest fluid change interval among all TX4 variants at 30,000 miles under normal use. Despite sharing the same 9-liter capacity as the other TX4 models, the tighter drain interval distinguishes the Euro 6 specification from its predecessors.
  • Across the TX4 range, the change interval shortened progressively from 40,000 miles on the Euro 4 to 30,000 miles on the Euro 6, a reduction of 10,000 miles between the first and last emission-standard variants in the TX4 lineup.
