Mine has had the gearbox software reset to factory setting & it seems to be better for a while. The problem seems to stem from the self learning program for the gearbox & after a short while it seems to revert to the same behaviour as before, I.E clunks & jerks. Well done JLR. The Evoque with it's myriad of completely useless & unneeded electronics is too clever for it's own good. :mad:

I guess there is more to it than JLR electronics.

I had a beamer with similar symptoms and after resetting gearbox adaptation, it used to get better for a few days. However, symptoms used to return after a few days.

Gearbox oil flush and adaptation reset resolved that.

I remember you saying that your car has been to the dealer multiple times. Have you asked them to change the gearbox oil +/- Haldex oil?

SSD (dealer level diagnostic software) suggests changing the gearbox oil if it cannot find a hardware error. The issue I see is that (presumably) most dealers are not bothered to do it and this information is not cascaded to us (unless your dealer is exceptionally good and honest).

Just for info I asked Bell Engineering if they would change my auto transmission oil. They won’t touch auto gearboxes.
For an independent view I can see no harm in ringing an independent auto specialist and asked their advice. VMTP Midlands Ltd know what they are talking about. They only deal with auto gearboxes.
I have no connection to them whatsoever (before you ask). But having rang several main dealers who hadn’t got a clue and several independent supposed Land Rover garages VMTP were the only ones who appeared to know what they were talking about. Very friendly and happy to give advice wether you use them or not.

Hi makkan,one of the first things renewed was the Haldex pump with new filter & presumably oil when the rear diff was also renewed, but I don't think the gearbox oil has been changed.

With those symptoms, gearbox oil change + sump gasket (if needed) is the first line of protocol and if that does not help then Haldex.

Worth of having a polite conversation with your dealer.

Hi makkan, many thanks (y) for the info I will ask the question when I take it in next time (which should be quite soon).

Just to correct:

Here is the response which I got from ZF UK (manufacturer of nine-speed gearbox)/


So, they do no suggest to change/ service the gearbox.

Unless there are issues and in that case, this is what JLR suggests:

When we go through SDD (JLR diagnostic portal), it suggests (selecting harsh gear change on troubleshooting):
1- Reset gearbox adaptation settings
2- If the problem persists, update the firmware of gearbox only.
3- Change the transmission oil if above fails.

Found this:



Not sure if this is applicable to your car, however, our American friends have this tranny (as they call) recall Q500.
