I have a cuore 2006 model , it has been used only 40000km .
I went for the gear oil checking of my Honda City , so I had it changed .
The mechanic put the zic gear oil ( I dont know which type but he put zic gear oil in it).around 1.5 litre gear oil was left.
Then i took my cuore for a check up , to the same mechanic . He told me that the cuore also needs gear oil replacement . Hence he put the remaining gear oil in the cuore.
Since that day , my cuore transmission is very rough. It uses a lot of force to shift into second gear .
So could the problem be caused by using a wrong gear oil? As in using the oil of same viscosity in cuore , as the one used in Honda city???
