Torque and power like you would not believe. His boat is massive as well. So is his trans cooler.

Thanks for that, so in my ignorance and wanting to learn a bit more, so what is happens to the transmission when this is happening. What parts 'fail' or become weaker as a result ?

I'll let the gurus answer that one.

I have posted this pic a few times to show how well my car towed. I towed that car about 1,000 km, on a hot day. The car towed it beautifully. Now, the car had around 260,000 km on it. It was serviced regularly. It wasn't too long after this that the car started to have some issues. The M + S flashing, limp home mode. If I stopped and restarted it would clear, but it got worse. So, I got the oil changed. It was black, and it stank. It had been changed about 20,000 km previously and was a good colour then ( I'd expect some discolouration, which was there ). The oil change didn't help, and a couple of months later the trans failed completely. No drive at all forward, still had reverse. The oil was black again.
I haven't done a lot with autos, as they scare the bejesus out of me, but to me black equals burnt, and the only things I can think of that would burn in the auto are the clutch packs or the oil itself. Both things suggest excessive temps.
To dry fill the auto takes around 9 litres of oil. That may seem a lot, but I don't think it's enough. If I ever get my car back ( don't ask ), I want to fit a much bigger cooler, first for the obvious airflow reason, but second for the increased capacity.
I am no expert, and don't claim to be, but I think my experience shows what I meant by saying the cars were underprepared for what we would ask of them.
Having said that, I like my Disco, and would prefer to upgrade it rather than replace it, and am following the various threads on here about transmissions.

That pic also reminds me, I want to reinstate the SLS.

TCT recommended a specialist gearbox company not too far from me, and the just quoted $1,200 to service the gearbox and change the TC over for the Ashcroft unit - Ouch !! But they do use good oil so they told me.

So looking like the whole project is going to cost $1,750 plus the postage to get an Ashcroft TC out here. Looks sadly like a back-burner thing, $1,200 wow, someone here said should be done for about $580.....

Phone around time I guess....

I'd keep saving and get a whole transmission sent over!

Did you note and check those injector codes? Worth doing before you spend on a box.. They're all readable with the rocker cover off....
