Missing in 3rd

[Beerdead]

I was driving up Carsons gap, on Thunderbolts way, driving assertively, and my 2007 2.7 TDV6 started missing drive irregularly. Did it a couple of times in 4th as well but stopped when I reached levelish ground. Dramatic loss of power and didn't think I would make it to the top. I got the impression that it may have been the gear box rather than fuel feed, but really couldn't tell.

I've done about 1000 kilometres since with no issues.

Anybody else experience anything like this, or does anyone have an idea what may have caused this?

When if ever was your transmission fluid changed?

[LandyAndy]

Probably need more info.
Was it a hot day,how clean are the radiator/condensor.
Could simply be the vehicle getting a bit hot and looking after itself.

I think you are experiencing the results of the traction control cutting power. Nothing wrong with the car.


If you push your foot to the floor this is what happens. You need less accelerator and steady power in these cars or they cut power to maintain traction. You should also be in low range so that the car sets itself up for off road driving and optimises its systems accordingly, including the cross link valves for the suspension. Different terrain settings also influence the amount of power cutting the engine gets.


As Andy said, some more information may make things clearer.

Ambient temp was 38C.

I've owned the car for 12 months and it was serviced by a reputable LR specialist several months ago. Presumably the transmission fluid was checked or changed. I know that this is no guarantee, but my experience with this mob is that they are thorough.

I didn't have the foot to the floor, but I was certainly driving rather than cruising, and it was a country thoroughfare, rather than a dirt track, so it didn't warrant low range. It didn't feel like traction control as I've experienced in loose conditions. There was a definite clunk with quite perceivable braking on those occasions. This was simply momentary intermittent absence of drive/power.

Carsons gap climbs about 600 metres in roughly 6 kilometers.
While there wasn't much of a load, I did have a fridge and 2 paddle boards on board, as well as clothing for a weekend.

The radiator is clean, and I wouldn't know where the condensor is.

Hope this helps.

Condensor is the "radiator" for the air-con,there is also the intercooler and gearbox cooler up front.If there is a blockage in airflow it will cause a temporary overheat in the conditions you mention.Check for bugs/grass/mud etc.You will find a section on it in the owners manual.

If you were using any terrain response programs, it is not just the traction control braking, it also manages the throttle,response etc. sometimes particularly when you are in grass gravel snow mode, if you are driving assertively it certainly can feel like you have just had all your power cut and it takes a bit of getting used to but perfectly normal.
