Dispite the negativity surrounding the 3.0Tdi,
mine has given me a good run and I'm thinking about going to the latest model, the new shape. I'll admit I'm also looking at other options but If I upgrade to another GU, most of my accessories will swap straight over...hence It's a good option for me.
Just wondering if anyone else out there has done the upgrade and what your thoughts are? I'm looking at going from the manual to an auto...anyone with any experience in this area?
Cheers

Hi Andrew,
I changed from a 2000 ST 3.0Tdi (which I did not have any problems with) 5 speed manual to a new 2006 3.0Tdi ST-S Auto.
I have towed a 16ft caravan and an Aussie Swag Camper. I found the gear ratios in the manual a little too far apart at times, with constant gear changing needed in varying driving conditions. I also had the issue about not towing in 5th gear, which meant engine revs at about 2800 for 95kph.
Having now owned both, I prefer the auto whether towing or just normal driving. At 100 kph the engine is doing about 2300 rpm - about 400 rpm less than a manual in 5th at the same speed. My only concern about towing with the auto is the transmission lock up does not operate until 80kph. So for driving at below these speeds (
Oodnadatta Track etc.) perhaps a little more heat is generated, but I have never had the auto trans temp light operate or the engine temp gauge show an increase in temperature under those conditions.
The only downside to the auto is steep off road descending. The climbing is great but constant use of the brakes is needed going down
hill even in low range with the auto locked in 1st gear.
I guess your final decision should be based on your intended use. But for me, I am not regretting the change to an auto. Good luck.

I have heard that you can fit a manual overide switch to the electronically controlled torque converter lock-up. Might not be good for the new car Warranty but would be good for such situstions you mentioned 80 km on a long trip. I have tried this on an older Nissan Terrano but I only have the ability to un-lock it no to lock at lower revs. It should be possible.

Try this for down
hill with an auto
Drive like a girl left foot on the brake and right foot on the accelerator
lightly braking to keep speed down accelerate so the torque converter locks up and it improves the breaking capacity of the motor.
I tried it freaked me out but it seemed to slow the car after about what felt like 5 to 10 seconds (was not timing it had both hands on the wheel). Probably a lot shorter than that given the adrenalin in the blood at the time.
Try it in a small
hill first to get the hang of it.
