Update
Yesterday morning I noticed a few red oil drops on floor. Without any doubt its transmission oil as its red. I looked under the vehicle and found two plastic pipes are in very bad condition and one of them was broken.
Without wasting any moment I went to mechanic and asked him to get new best available pipes. Flexible hard walled pipes (Made in italy) were looking good and I hope they will last long. Whole job took only 20 mins. Cost was Rs. 240 for 3 feet pipe, Rs. 20 for two clips and Rs. 300 labour.
Moral of the story. Now my long distance journey will include rubber pipes of different sizes & diameters and clips along with other recovery kit and oils.
