Nope. Used search for anything torque or converter. Nothing as simple as that. There are some that show numerical values of no meaning but no torque converter status (on mine at least).Quote:

I guess you could have also been punching in to a head wind at the time without locked coverter.
Is this such an issue as the ECU system in the car will tell you if the ECUs think the oil is getting too hot? Doesn't the system shut the car down with a display on the dash if things get too hot. It has safety margins built in.

It is good the ECU does adopt a cooling strategy when the transmission gets hot and for rare instances would be adequate, but it kicks in at a pretty high temperature in my opinion. Looks to be more about preventing a catastrophic failure rather than being good for long life (what ever that means for LR).Quote:

1 - Don't forget 215K km / 2017 transmission rebuild, then double ATF change at 232K km/June 19, and then a single change at 253K km / Oct 19. That many changes should provide pretty fair flushing surely? Then again we are talking LR[bigwhistle]Quote:

Partially correct - I did get one gearbox warning which I think drops the trans into 4th/5th as the revs go up. Stopped car, turn off ignition, restart, all good. I did note that before I stopped, the revs would drop to idle on a trailing throttle at speed on a downhill slope.Quote:

No response until about 140C (according to GAP Tool) at which point I'm getting concerned), then drops to lower gear/higher revs with then a yellow triangle warning, requiring ignition off/restart - which in turn provides an interim cooling off.
That is interesting. The above extract was the training material from 2004 prior to release, so maybe they revised the software to allow for even higher running temps. Which would be a worry but not surprising when at the time LR also considered it was OK to never need to change the transmission fluid either.Quote:

Should be easy to fit an external transmission cooler - it was a common kit for the Falcon’s and the piping changes to 1/2 inch hose just before the radiator. I know most don’t think this is required with the D3/4 but if I was doing a lot of towing I would want to keep oil temps below 100 degC.
Interesting reading Gavin, you did mention when we spoke thst you wanted an aux cooler as the engine /transmission ran hotter than you believe is cortect. Im sure you will have investigated the obvious re engine in terms of coolant correct SG and coolsnt to demin water ratio etc. I also wonder if theres maybe an airflow restriction to the transmission oil cooler mounted under / in front of the engine..Quote:
