Symptoms
Harsh or flared shifts, judder, a weeping pan or valve-body sleeve. The handbook calls the fluid 'filled for life', but owners and specialists change it.
The fix, step by step
- 2010–2013 trucks use a ZF six-speed with a plastic pan and integral filter; 2014–2016 trucks use the ZF 8HP70, whose LR065238 pan also carries the filter.
- Drain, drop the pan, replace the valve-body sleeve on six-speeds, fit the new pan, then follow the factory fill-and-level procedure, which is done at a specified fluid temperature.
- Several six-speed owners have switched to a steel pan with a separate filter to make future services easier.
