 The XF was launched with only an automatic gearbox, and all models initially used the six-speed ZF 6HP26 automatic transmission.For model years 2010–2012, some engines (the 3.0 l diesel and 5.0 l supercharged petrol) used the second generation six-speed ZF 6HP28 transmission.During 2012–2013, 8-speed ZF 8HP70 transmissions replaced the 6-speed transmissions for all engines.
