Thank you Rahimdad sir this gives me encourement but was also wondering why my pajero could have possibly lost some early climb accelaration in the very last part of the drive. I am getting it looked at today.
I noticed some heat up as well. This is a 3.8 V6, model 2005 car done over 250k with recent transmission overhaul. There is some solenoid issue with the transmission panel light blinking differential where the rest of the wheels switch off.
Below are my failed Attempts; where near all attempts made by other drivers succeeded:
1. Accelerated on D and just at the near of ridge shifted to manual 1 gear to give it that push.. car slowed down and was 15 metres short.
2. Accelerated and when halfway hit 1 gear, managed to reach a bit higher than 1 attempted.
3. Third attempt went totally manual 1 gear acceleration then hit 2 gear and 2/3 climb hit 1 gear again, could almost reach the edge but not climb over.
However, twice early part of the drive, arc and climb I could do it with D and 1 gear easily. It is only the last part of the drive where the car was not picking the early acceleration.
Maybe by practice as you and Gaurav jee suggested I might hit the perfect combination as well rectify any other issue if there are.
Thank you so much.
