Hi all,
On my recently aquired RR 4.2 Supercharged I have noticed now and again a thud (ish) change down into 1st gear as the car is stopping.
I have heard it may be a "reset" needed, any ideas.
Otherwise it changes all gears seamlessly and very smoothly.

Thanks

Glynn

Same on my 07 Supercharged, keen to hear if theres a software update or similar I'm missing

Maybe worth a read ….

"Open Mike Night " sounded like a lot of fun until i found out i was going to an Autopsy

Had this on my last SC and Land Rover sorted it with software...

Mine is having this LTB done when it's next in. It sorts out the harsh shifts 1-2-3 and specifically a lift off throttle 3-2-1 shunt.

LTB00267 - Harsh Transmission Shift 1-2 & 2-3 Lift Off Throttle (L.O.T), and 3-2 & 2-1 rollout


It's a software issue and takes 0.2hrs apparently.

In my TDV8 I found the same issue and having the auto box megaflushed made a huge difference to the smoothness of all gear changes. Discovery 4 HSE

Mmm . . . interesting.

My AJV8 does this - I thought I'd read somewhere on here this was a characteristic of the ZF 6 speed gearbox ?

So it can be "fixed" ?

 Where do you go after one of these . . . ?

Yes, and the sooner the better IMHO as it will only do damage in the longrun...

"megaflush"

Mine is due in for a service, with it towing for about 30% of it's life is it worth me specifying this type of gearbox flush...the 'box isn't showing any signs of problems but preventing is better than curing ? Is this where I put the car details and a bit about myself ?........

^^ Thanks Craig - I'll look into that.
I take it that as it takes 0.2 hrs to complete it is a "laptop" job ?

 Where do you go after one of these . . . ?

Not sure on 0.2hrs or costs as mine was done as a "favour" by my friendly local MD (who supplies my parts and i convert their customers cars etc)

I will say though, it took a couple of attempts to get it right first time made it far worse But got their on the second/third attempt... So ask them if you can roadtest it when they have completed their work (to make sure your happy with the results )
