In park the gearbox oil will heat up faster, yes? So maybe in N with the handbrake on?
And why pray tell us would the fluid get any hotter in park than it does in neutral?

My theory was the output shaft is locked but the engine is still spinning so that energy will be absorbed by the gearbox (fluid) whereas in neutral both shafts are free to spin so less friction and therefore less heat generated.
It makes the thingy me Bob's rattle! You know that grrrrrrrrr!!!No my friend not so. Have another think about what happens when the output shaft turns.

IIRC the 4HP22 had issues if left in P or N at high revs, but this was supposedly overcome before the P38. I don't know what the issues were but again IIRC I think wammers had an idea.
No. It was the 4HP22. I've been having a bit of a play on google today & there's a LZ thread (amongst others as it's a widely used box) on the subject - which annoyingly I can't currently find or I'd link it for you.

I'm going to leave it in park, as I do not want to run over my self, it would ruin my morning!
The owners handbook suggests that neutral should be selected when stationary much as you would with a manual.Not sure about the HP22 but I'm pretty sure there was an issue in older autos overheating or eating the boxes when left in park for long periods with the engine running. Or maybe it was leaving them in D with the footbrake on. Actually, probably the latter thinking about it.
The only difference is the gearbox lock pawl engages when in park locking the output shaft thus stopping the wheels turning.The output shaft does not turn either in neutral nor in park. It makes no difference park or neutral, to the topping up of the gearbox. But park is the safer position because it prevents the wheels turning.
One good thing about the 4x4 panda is if you get stuck couple of good blokes can lift it out.Life without my panda is sad
