That is not the summation of my experience, you are being ridiculous.

Oh thats right lets not forget you gave your Landy a drink in 200mm of water.... Amatuer.

But I've never liked any I've driven off road. That's personal preference.

Wow, this thread has kicked on from this morning.:). I'm none of the above actually (well, maybe a bit of a grammar nazi;)) but I do own 4, 4 wheel drives - 2 manual and 2 auto. I accept that you may not like autos - that is personal preference, and I actually agree with you there, I prefer to drive a manual, but I was just picking you up on your sweeping generalisation that auto's have no control off road. I find on both my old RRC and my new L322, and other auto 4WD I have driven, that you have far more control than in a manual. The only downside I believe they have is that even locked into 1st, they don't give as much engine braking as a manual would. This is of course alleviated in the L322 by traction control and can be addressed in older vehicles with the use of a custom low stall torque converter.

So personal preferences aside, I was just pointing that out. :). No need for name calling either, it doesn't do anyone any good - that goes for everyone here that has posted - c'mon people, we don't need that sort of thing. Lets stick to a robust discussion that doesn't decent into the gutter. We're all (mostly) grown ups here that should be able to take a bit of criticism without taking it to heart. :)

Cheers - Gav

I'd accept being called a ****** over that... but otherwise I don't see your point? I'm sure you would have done some stupid things when you were young, on the plus I learnt how to re-build a diesel, I know what I did then was young and stupid, I've learnt, if anything it has given me more experience. Your point is moot, bugger off.

Gav, I apologise, the troll comment was not directed at you, in the sense I meant "are you trolling me", poor wording, it was not intended as a personal attack.

No probs mate. :)

Actually a clutch can lose 100%. That is exactly how they work.

Torque to the wheels depends on total gearing. The torque converter is an extremely inefficient way to increase torque and it does so at the expense of power and the production of a lot of heat.

Hence the oil coolers and lines so more of the energy you put in the tank gets lost as useless heat.



Try picking the right gear first.;)



I'll bet you use the brakes heavily. My ZF only locks up over about 85km/h on road in top gear. It can't be made to lockup downhill on over-run at slow speed.



You've now introduced a TD5 flywheel to try to balance out the argument for a 300tdi automatic?:eek:

My facts are 100% right. Some you clearly didn't read (oil coolers & lines), others you've tried to divert the argument around.

Really??? You really think all autos works that way all the time? Have you ever even driven one? Try selecting some of those gears below the 'D' - you will be pleasantly surprised...

Or, maybe there's something wrong with the ZF in my RRC and the GM in my L322 - they stay in the gear I select when I want them too...:eek:

Yes I have driven and owned several. I have a RR ZF HP22 parked outside right now. Your comment doesn't in any way change or refute the statement you replied to.

You can select a lower gear in some gearboxes (computer controlled ones will over-ride you when you hit the prescribed rpm), selecting a gear higher than the gearbox wants to use does nothing. You have a limited range of throttle motion before the gearbox wants to either kick-down or try a higher gear (if available for that speed/load combination).
Remember this discussion is about the fully hydraulic ZF HP22 on a 300tdi.

This combination makes it impossible to use the best efficiency points of a diesel engine. Which is high load and rpm around max torque. Try to get max torque and it unlocks the TC and chops down a gear, sending rpm up and efficiency out the window.

*edit*
But yes, there probably is something wrong with the GM in your L322.
*shudder*.

My 1996 300TDI doesnt have and oil cooler on it but my 1997 V8 does? - both manuals.

Should the 300TDI have a cooler?

:Rolling::Rolling:I'll pay that one - there defiantly IS something wrong with that box....
