I am quite sure if your transmission is in good condition it should be able to go up from Kiwai to Shogran. But why do you want to torture the car? It would be cruelty to the car. Still If you want to take your car up then better to have 2-3 in it and remaining on a jeep or on the second trip. I am sure you must have luggage in the trunk too. After all its a 1.3l engine with an auto tranny. You should expect car like performance rather than expect it to act as a 4x4.
As for competing with a manual GLi when climbing uphill, the manual will perform a bit better. That's why I am a manual tranny fan(H)
