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.

No my friend not so. Have another think about what happens when the output shaft turns.

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.
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.

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.

Yes, that would be enough to mix me up. TFI have the manual on my '95!

If you don't you may need to change your screen name to "Flatpandaman".

The owners handbook suggests that neutral should be selected when stationary much as you would with a manual.

The only difference is the gearbox lock pawl engages when in park locking the output shaft thus stopping the wheels turning.

Just to throw my two pence in. My 2.5 started to rev it's tits off on hills like yours is in your video. It was caused by the viscous fan going bad and remaining constantly locked up (which was robbing the engine of what little power it has). It might tie in with your coolant temperature remaining low all the time too.

If the engine is running cold it will effect available power. Power is restricted at lower engine temps.
