One thing I forget to add in ad is Transmission oil flush....
I recently did transmission oil flush by myself according to Xulifqar's method. Took all old and dirty trans oil out through cooler lines which was about 7 liters and put round about 7 liters new and fresh ZIC ATF Dexron 3 in it.... Receipt is available because new ATF bought from ZIC Authorized dealer.
Now shifting is too smooth and shifting response with gas pedal is extra ordinary improved.
