I was using Yeti to pull a stump out and it would baulk under load - effectively stationary under load.

So the question is what is going on in the transmission seeing there is no torque converter?

Is it clutch slip? - not good at all if it is.

What did you expect? Wheelspin?

Yes, it is clutch slip.  Not great, no, but then driving against an (ostensibly) immovable load isn't the best idea either!

Just as I suspected.

If you buy it thinking it's an 'automatic' and drive accordingly, you're going to get a nasty and expensive shock.

It does not have the power and fuel sapping torque converter that makes the 7 series Volvo's so good at pulling trees over with the roots following :sun:

Can i ask what you use as a Tow Point,

Do you use the Tow Ball, or the Original Tie Down / Recovery points, or do you have Strengthened Offroad Recovery Points and a Bridle.?

 

The car has tow limits, but Snatch Recovery or Stump Pulling is not one of the forties that a Yeti stands up to well.

Crumple Zones at the Front, and Towbar attachments are not up to it, unless it is light work.

It was a fairly short tow rope and the tow bar was not put under much stress, simply stopping the vehicle from idle in 'D' then holding on the brakes in neutral.

It was a palm type shrub which had matted roots.

It just got me thinking that it mustn't be thought of/treated as an automatic in the old fashioned (now) sense if you want a long life out of the clutch packs.

I'm also wondering if the the hill-hold function couldn't be programmed to activate when in gear at idle but not moving for any reason.

Probably no worse than what I used my old Passat for:

Have a read of SSP 851402 - The 02E Direct Shift Gearbox Design and Function - in the link below.  If I understand that correctly, the clutch cooling lubrication system (page 36) will have had a bit of work to do to keep the temperature under control.

The Yeti did not work but we saw you getting it out a bit later

Link doesn't work.

Works for me in Firefox, Microsoft Internet Explorer and Google Chrome.

Works okay for me too!

The 02E is the 6 speed DSG gearbox used in the more powerful engines.

 

This has lubricated clutches.

 

The 7 speed clutches are not lubricated.

I believed that the OP's 103DSG has the 6-speed gearbox - which is why I posted that link - unlike my 1.2TSI with the 7-speed DSG as in the link below.

If the tachometer represents crankshaft rpm - how can it show a ~ 500 rpm increase/decrease in a micro second at a gear change without an sense of a shift shock (anything but)?

how can it show a ~ 500 rpm increase/decrease in a micro second at a gear change

I doubt tachometer stepper motor can move the needle that fast. 500 rpm in 1/16 of a second seems more plausible

Oooh. I didn't know about this car with that engine/gearbox combo.

 

I've learned something new today. I stand corrected.

The tacho is supposed to represent the speed of the crankshaft and how it can change 500 in a blink is a mystery to me.

In a manual a snap change would be hard on the synchros.

If my calculations are correct, the crankshaft in an average 4-cylinder engine experiences accelerations of about 2160 rpm per second when idling. At each stroke. That is 135 rpm in 1/16 of a second (~each 0.01 second). Yet you hardly notice it. And that is comparable to 500 rpm in 600 milliseconds (or whatever DSG shift time is).

In a manual a snap change would be hard on the synchros.

That's why the DSG is, effectively, two gearboxes in one.
