Hi again,

I've recently in the last 1000 miles had a mega flush and filter change done on my 6 speed box with reset adaptation, the car is a TDV8 and now changes nicely and smoother to drive.

I've just uploaded a Bell Auto Services remap/tune alongside the EGR patch I bought off Pete Bell back in May, all go so far, its nicer to drive off boost with more urgency off the line straight away, I can tell it has more go as well, but not been going mad, as I understand the calibration needs to learn over the next few hundred miles.

I know looking at the ECU info on my GAP iid tool that I could if I wanted to upgrade to the latest version of ZF 6 speed gearbox updates and wondered if anyone has done the same and what benefits they experienced.

I know the LR and Range rover communities are wary of updating certain aspects of ECU updates, which I'm not sure why? "if it ain't broke, don't fix it", why otherwise did LR release the update then????

My car has just crept up to 99,000, so still a strong unit and gearbox behaves as it should to my knowledge after what was its first oil change in 15 years by the colour of it!

Any suggestion or advice would be greatly appreciated, I know I can contact Patrick at GAP to get the update sent across, but wondered beforehand what other enthusiasts experiences were beforehand.

Cheers Dean

My 3.0L V6 has just covered 140,000kms and I got the mechatronic seals changed out yesterday. Obviously, as it drove out of the workshop, the shift points were all over the place. Furthermore, there was an obvious lag shifting from 3rd to 4th.

Back home, out with the Gap II tool. One quick adaption reset, the gearbox shifted much smoother but there was still the lag between 3rd to 4th. Set it into command shift, drove it for 2-3km manually shifting up & down between 3rd and 4th. Now the lag is gone, shifts smooth and it behaves like a real Range Rover should.

generally I wouldn't update it. However, there is a fix for something call the californian shunt or stop.
Basically when slowing down and decreasing thru the gears, if you get an unpleasant feeling then an update should sort it. So if you get this, or it bothers you, then you could update it.
