Asalam O Alaikum..brothers I admire your knowledge and expertise which are really outstanding, I need some help regarding my City 2005 auto petrol, I owned this car from last 10 years and it was performing like heaven, I don't know who suggested my brother that you guys need to change your gear oil as its life is nearly end, so he did the same thing with the help of some mechanic they changed the gear oil ATF (as written on the oil gauge) and from then this car became a disaster for me, after that the major issues I faced are as follows,
Poor pickup
Knocking Problem
Vibration problem and it became worst on AC, but it all happens on D or R, Car seems very smooth on P or N even on AC.
Fluctuation of RPM
Very bad performance mileage 7 to 8 km/ltr
Generates very irritating ter ter sounds when on low speed like 5 to 10 or on picks (on AC)
Badly jerking
But it all happens in slow speed or on picks, once the car on pace or in constant speed it flies like unicorn. I tried more then 6 mechanics for different opinion but they all have only one solution is to replace the transmission (gear box) with kabli one. I visited the Honda 3S SITE Karachi, and without any test drive or scanning he suggested me the same solution (change of gear box) and when I request him to please check it through scanner or any tool, he told me " bhai humara roz ka kaam hai".. Now I am stuck what to do? Please suggest me what to do now.. Please respond ASAP
If any other brother can help or suggest me any mechanic in Karachi it will be a great help.
