assalam! dear i have issue in the gear box, when i bought the car there was just 4 forward gears in it. then i tried to overhaul my car mechanically, in this process i also tried to put 5 forward transmission. the shopkeeper told that what is the problem with your car gear box, is there any sound in it while driving, i said NO its ok but just to have 5th gear, he told me that dont replace it , i will fit the 5th gear in your own gear box and then he fitted for 3000 Rs. Now i there is an issue in the first gear, when the car is moving means running i cant put back it in to first gear but when the is idle then the first gear is very smooth and comfortable.
