    Trans noise on start up

    Now the winter has hit Perth I have found that when I cold start my Puma I get a trans rattle. I checked the owners manual and it states depress the clutch when starting and have noted that this fixes the problem. I have also noted gear rattle not unlike Nissan Patrol gearbox noise at low RPM and am wondering if this is normal. Otherwise the transmission is great. Perhaps I am overly concerned???

    Always start the vehicle with clutch depressed and in neutral - as you are. On cold mornings, it is normal for diesel engines to have some chatter noise - mine does so for a few seconds - then is quiet.

    And even though I have seen debate on the issue, both the local LR dealer and LR specialist mechanics (MR automotive) have advised me to warm the engine for 3-4 minutes before driving when the engine is very cold. Then - take it easy until the engine reaches operating temp.

    If you are doing these things - I wouldn't worry.

    Curious as to why you say that . What effect does it have if the clutch is not depressed but in neutral. I know what happens when it is in gear and you start it.

    Thanks

    I mentioned this because it is stated as the procedure in the Puma's manual.

    I am not sure of the technical reasons why this is recommended - however...

    In the past, I have started it in neutral but with out depressing the clutch and you hear weird clunking noises and feel vibrations from the gearbox - so I follow the stated procedure now.

    i just dont understand why we just cant start them like any other bloody car......

    I think the manual has been written with all these little tricks so you don't here all the friggin rattles.....probably nothing to do with the tech side of things.

    I had a diesel Jeep Cherokee once that would not start unless the clutch was depressed. Apparently that's the way Jeep designed them so I simply follow the same procedure with the Defender. I also have the vehicle in neutral just to be on the safe side so I don't inadvertently put myself through the back wall of the garage!

    Just got back from Barbagallo Landrover as this rattle/noise seems to have appeared only recently. They say its the clutch and that it could be a week or so before they will get the parts. Here we go again. My transmission should know how to pull its self out by now. This car just keeps getting newer each month.

    Yep, I find it a bit embarrassing when someone else drives mine and leaves it in gear.

    My clutch (spiggot? bush) squeaks and groans until it has warmed up so I prefer the rattles.

    I read the instructions as a means of indemnifying themselves for when some does start it in gear and causes damage. So outside of that there is no other mechanical reason for starting with clutch engaged.

    Cheers

    That's no good, Allan - Owning a LR is a process of getting the last 5% of what Solihull didn't do right the first time sorted - hopefully within the warranty period. Good luck and I hope you are all good to go soon. These things are really annoying especially as we all throw plenty of loot at our trucks.

    Well - a google search on the topic comes up with answers to your question from all sorts of angles. All I know is - mine makes noise and vibrations which don't occur if I follow the instructions in the manual and depress the clutch and shift to neutral - so I do.

    With new cars it's all about getting more from less,you can't just drive away because it takes time for all the technology to warm up and work,there will be more complaints now it's cooler but that is life.This week it has been cold,I've been working at Kambalda right on a salt lake and it's freezing,you can hear the D4D's rattling fom a mile off,the one I was driving on tuesday sounded like a box of spanners thrown down some stairs.
