Using Honda City 2010 Model . It was in perfect working condition before changing the gear oil @ 43000 KM.
Honda Faisalabad was running out of original Honda Gear Oil stock so they bought original Honda Gear Oil from local Market. After changing this gear oil , early morning when car start car for school , the second gear becomes too hard and takes some additional pushing to gear in , after some time its become smooth.
There is no issue in 3rd and 4th gear.
Secondly car loses power * acceleration"second gear. lowering speeds from 3rd or 4th to second gear. Mostly stepping down from higher gear to 2nd gear feels race paddle don't work then slowly slowly it gets pace to gear in 3rd gear. Not pick power in second gear while bring back gear from 3 or 4 gear.
Car don't accelerate in second gear from coming back from 3rd or 4th to 2nd . Its Ok from 1 to 2 gear.
No issue of power loss in 3rd and 4th gear . Very smooth and excellent performance on high gears and high speed.
I have change so far , Fuel Filter , Plugs , Engine Oil Mobil 1 , 0W40 , Only using HIGH OCTANE other wise knocking issue become sever in second gear.
All parts Honda original and all fixed by Honda .
