Transmission Slipping - problem?
Don't know if this is normal, I owned many cars and never seen this.
When its below freezing and I drive my RR within minutes of startup the RPM runs higher in every gear without the speed being faster, like its slipping much more than when hot.(all auto trannys slip a bit all the time)
50mph 5 gear when cold = 2400 RPM
50mph 5 gear when hot = 1900 RPM
(Those are just arbitrary numbers)
I also have a video here:
RR dealer garage could not explain it, they didn't even understand the video after watching it?????

Torque converter may not be locking up till its warmed up is my thoughts
I was thinking the same thing except:
1)Why couldn't the LR service tell me this?
2)Won't that amount of slipping cause excess wear? I never owned a car that slipped that much.
You sure it's not the gauge? I couldn't tell from the sound if the engine was actually changing RPM.
It not wear persay like we used to think of with bands in an old tranny.
That is the torque converter and to me it is NOT an issue. With 9 speeds and very close range between gears that is fully comprehendable. Even on my old Ascender (4speed auto) 3rd lockup v 4rth non locked has overlap.
Its not the gauges because
1) I can hear the engine rpm
2) when engine gets warm all is ok.
I don't think it's normal. What happens when you leave it in drive or sport, without using the paddles, and step on the gas to trigger a down shift? Does it shift quickly?
You shouldn't have to stop just because the pavement does! 2012 Range Rover Evoque Pure Plus Coupe, 2009 Land Rover LR2 HSE traded, 2008 Land Rover LR2 SE traded.
VERY good question! If it downshifts fine its what I was describing. Make sure you get the latest software upgrade. At least in sport mode its pretty darn good now. granted I think the NEW sport mode should be drive and a real sport mode should force a downshift below 1800 rpms but....still don't like lugging at 1600 rpms...eventually I'll just get a custom tune done if the engineers at Range Rover won't listen.
