I have noticed this terrible issue in my last two long drives. 1. Drive at around 100Kmph for long time ( as in long distance drive) 2. Shift to lower gears 3. Changing gears to and from 4th gear is very very difficult. I have to practically use all my strength to get the gear shifted out of 4th gear to 3rd or 5th. It also appears that the shift into 4th gear is not complete- seems stuck somewhere in between (observing the position of the gear stick). 4. Problem is seen even if you turn off for half and hour or so and resume driving. I have seen this problem in my last two long drives. I suspect this could be something going wrong due to high temperature .. Driving through city traffic doesnt show this problem. Though I suspect the gear shift isnt as smooth as it should be.
