Transmission smoke when hard accelerating.

Well, I know the smell is of the transmission fluid. And when I park after the car smokes, red fluid can be noticed under the car (not a very big amount though).

When the car is being driven easily all is fine, but when hard accelerating, and when going mountain roads, the transmission throws fluid, and it starts smoking.

I installed an external transmission cooler to make sure it's not a problem with the oil. but still the car does the same symptom, what do you suggest?

Is this a symptom of the torque converter?

Sounds like you have a leak somewhere and under high pressure it seeps and with the higher temperature it starts to smoke. Find the leak

Well not really, there's no leak under the car. Even when its turned on. This symptom only occurs under hard acceleration, there seems to be a problem with the transmission. I really don't know what exactly is happening but its an unknown symptom.. I wish anyone which experienced this problem can help.

Check your front pump seal.

the oil is directly under the transmission oil pan. At first the workshop assumed that the oil is above the maximum level, but when checked, it showed that the oil level is fine. Will check the pump seal.

+1 for pump seal,,

also check the pan gasket & pilot spacer as well, those most common leaks in 722.6...!

ZAYED,,
