TIP-TOP TRANSMISSIONS

All XKs used automatic transmissions, from five-speed ZF or Merc units early on to a sixspeed ZF later, the ‘J-gate’ selector allowing easy manual control. None of the boxes are entirely trouble-free at higher mileages, so ensure gearshifts are smooth and without hesitation or thumps. Supposedly sealed-for-life, a £200 oil and filter change at around 60k miles is advisable and can improve smoothness. Back axles are bulletproof with regular oil changes.
