Stiff gears in Mehran EFI 2012, around 150,000km driven.
Gear shifting is very stiff (no grinding) from the beginning, both with engine off and on. Rest everything is ok including gear oil level.
Thick viscosity gear oil is used i guess, so replacing it with ZIC gear oil with thin viscosity (red bottle) be any useful for it or not?
New clutch plate, pressure plate, clutch bearing and flywheel polishing is done recently as required.
Any solutions or its normal in Mehran?.
