Thread: G’day everyone, welcome me to the family!

I understand that the 8-speed programming when mated to the 4.4 in the L405 & L494 is an improvement over the programming for the 4.4 in the L322 but I find manual shifting in the L322 for the first few gears taking off from lights far superior to allowing the gbox to change out of 1st very quickly then slip the TC for 2nd and 3rd when towing my 2.5T van.

Recognition of trailer must be dependant on trailer light resistance, the trailer I am using isn't recognized by the car . Trailer lights are LED and all work as required. My own trailer is recognized this trailer is a loaner.

I wonder if it automatically chooses the correct gear box setting to prevent top gear use? My vehicle has Tow Assist so it wouldn’t surprise me.

For what its worth I tow in Sport mode and (mostly) using the paddle shift in the 8 speeder with my D4.
It is an absolute joy using the paddles when towing my 3.1T Caravan and using my Scanguage I watch the trans and engine temps and drive accordingly and also mindful keeping revs uppish to avoid high exhaust gas temps.
Usually run around 2,500-2,800 ish revs which it loves.

When using Sport mode the trans does not shift automatically and thus it expects you to do it, so it is virtually a 'manual' which is great.
Great for holding gears descending steep hills.
However if you forget to change down at a traffic light for instance, the 'puter accepts the fact that you have had momentary brain fade and overrides your decision & changes gear accordingly.

If I say, drop to 2nd or 3rd up one of those steep West Coast (Tassy) hills the engine and trans temps will rise to around 104/6 deg (at 106 the engine fans come in) but as soon as I start descending and with no load on the engine I paddle shift (short shift) up to say, 7th or 8th and the temps will drop down to early 90's within a klm.

Brilliant!

Yes that's right. This from the manual explains the minimum current/wattage requirements on the indicator/brake light circuits for the trailer to be recognised.

Might be good to keep an inline LED trailer light shunt handy in the car for LED based trailers that don't have the resistors installed.
