Cars Q&A

Hello, I have bought Santro Xing 97 model. It is perfect to drive in all ways. But the car gives problem only at one point. Even with the slight inclination the literally falls to pull in 3rd gear. If the inlination is little more car not even pulls in first gear. I showed it to the service man but he says every thing is perfect. Can you please suggest what might be the problem with my car.
