When you select a gear manual, the brain will open up all (most) of it valves simultaneously. Which means a lot of transmission fluid is going to get pushed around your box. So it’s a good way to “flush’ out any dirt that might have collected on the friction plates and other bits. Do this once a month or so.
In my A-star automatic, the user manual specifically asks to start the engine and keep the car on brakes while holding on (manually) to each gear for 10 seconds each, before checking the level of transmission fluid. I always wondered why, but this explains the logic. Thanks so much!

What I do is to down-shift manually when I go down a slope (rather than using the brakes), so I would be doing this at least once in a month.

This is interesting. Concern here is only over heating or is there something more to this. I have an auto i10 and i have an habit of putting the car to neutral while driving whenever i see a signal or traffic jam approaching. So does this load the engine?

No, it does not cause any harm, as long as you don't turn off the engine.
Only demerit is reduction in engine braking.

Transmission cooling will continue to happen, as long as engine is ON.

Much has been discussed about this here: http://www.team-bhp.com/forum/techni...ic-lights.html (Automatics : P or N at signals / traffic lights?)

Putting the car into neutral does not load the engine in any way.
