This article refers to the ZF 6, 8 and 9 speed units.

If you’re experiencing a gearbox delay with a Jaguar Land Rover (JLR) vehicle, this can refer to a few different symptoms. Here’s a breakdown of what might be causing it, potential issues by model, and what steps to take next.
A gearbox delay usually refers to:
- A hesitation when shifting gears (especially from Park to Drive or Reverse).
- A lag in response when accelerating.
- Jerky or delayed automatic gear changes while driving.
But most of our customers complain of a delay when pulling out at junctions, roundabouts or going for an over take.
Happily here at Tuning Emporium, we can help. As part of our remapping procedure we can also eliminate 99% of these flat spots, that customers face.
We do ask that the gearbox has been serviced before any tune takes place , to ensure the tune will work more effectively. JLR will say sealed for life which is rubbish, go on to ZF website, and they’ll recommend oil change every 60k!
From our 16 years in the tuning world, we can almost guarantee that customers will also experience better fuel economy too.
