These two has three functions ; lubricate, cool, protect.
Lubricate : you know by the word itself
Cool : Transfer heat from one hot place to another cooler place, eg. oil pan
Protect : protect from metal to metal friction, overheating, grinding, and whatever other possible reasons.
An ATF Cooler can help you take care of your gearbox by cooling down the ATF. Your ATF in Gearbox is overheating if you're going up genting and it jumps to free gear. This can be solved by adding ATF cooler, and of course, LUBEGARD 'black high friction modifier' atf additive which is proven and raises the boiling point of your atf.
Changing your 4litres of ATF to synthetic in your gearbox is not gonna do any good. If yes, minimal. The secret is that you have to flush your gearbox if you are to change to a different type of ATF. Not many workshops in this country has the machine to do it. Your gearbox will probably have a total of 6-8litres inside, that includes ATF that's left in the torque converter when your engine is not running and when you are doing an oil change.
Flushing process takes 8-14litres of new ATF. Change 4litres only, you'll only contaminate that particular 4litres of atf lol. By flushing, you may be also able to get rid of some minor problems such as late gearshifting, etc.

Yes, some people do believe in flushing. Well, pouring in just a flush chemical is not really gonna help. The best method is to pour the flush chemical in with fresh cheap new engine oil and let it run idle for like 20mins, drain the oil, pour another round of 4litres cheap oil and drain again. By then, you're able to pour in your desired oil already.
Observe this :
Do a flush process, your new oil lasts longer and turns black at a slower rate.
Dont do a flush, observe how fast ur current oil turns black.
Of course, there are some flush chemicals that are harmful to ur engine, that i must admit. However, some are not - These good chemicals not only removes sludge and carbon in ur engine, but also CREATES A COAT OF PRIMER WHEREVER THERE'S METAL TO METAL FRICTION. With this done, you don't need any other engine oil additives already
Added on April 8, 2010, 11:20 pmI did mention Lubegard's ATF protectants.
Common failure on a BMW E36 328i's gearbox is that it breaks down at a certain mileage (which i cudnt remember when). Lubegard was used since the car was bought on day one, and it ran an additional 100k km extra till it breaks down compared to other cars of the same model that was bought at the same time.
