Q. about the transmission on the new FL2.

willo · May 3, 2009

Hi all,

Sorry if this was covered already in the past but haven't seen/found anything similar. Question is: the transmission of the FL1 has the VCU to adjust the power to the rear axle, this when slipping frontwheels are detected. What system does the FL2 have please ? It's not a VCU, is it true what I heard from someone that it is an Haldex-clutch instead ? (Like on the VW 4Motion, Honda CR-V etc ??????) Tried to find this info in the "technical" part of the Belgian LR dealer's info. re the FL2, but all it says is that it's either an automatic (fuel engine) or a 6speed manual with the auto. as an option for the diesel. Nothing else/further explained.
Thanks.

Hi ya Willo
I am lead to believe that it is similar to the X-Trail - ie it is an electronically controlled clutch to the rear wheels.

Thanks MHM,

So it is indeed an Haldex or in other words, no permanent 4wd but just 2wd until slipping frontwheels are detected and then (with a few milliseconds delay) the power goes partially to the rear to make it 4wd ? Or is it also tuned to have always limited power going to the rear, as with the FL1 where it is about 6% going to the rear all the time ?

i believe so - but if its like the X-T it uses various sensors such as will slip, acceleration, g force sensors, speed, gear selected, to decide whether it is locked 4wd, auto or 2wd.

I found this on the internet;

Instead of a viscous coupling, the Freelander 2 uses a Haldex multi-plate clutch operated by hydraulic pressure. It's pre-loaded as soon as the engine starts, to ensure there's some rear-wheel drive straight away, thus preventing a spin and a chirp from the front wheels if you move off smartly. If needed on the move, rear-wheel drive can come back into play in just 150 milliseconds or within 15 degrees of a front wheel's slip rotation.

It ios basically a Haldex coupling, but with mods to make it more responsive as Howardo says. In general running it is meant to send about 30% of the torque to the rear. I believe the only time there is no drive to the rear is if you brake hard enough to bring the ABS into play, when the drive to the back is uncoupled so that it doesn't interfere with the ABS working.
