It all turned into an anti-climax. Gearing up to slug it out with Fortune over the paid CSC replacement, I got a call the same day in the evening that the CSC replacement was free (it bloody well should be) and that the car is ready to be picked up. Problem is the call came in at 6.15 in the evening so I told them I would pick it up tomorrow. Invoice came to Rs.495 for a new air filter. Invoice mentions new CSC (Steel). The underbody sound was the engine gaurd which the invoice says was re-fitted properly. The sound is gone so I guess they have it solved. First impression is that the gears slot in so much better, so smoothly. The resistance while shifting to fifth is gone. The jury is not yet out on this one but, oddly, the steering probably feels a wee bit lighter. I don't know if it's connected and how it's connected. More updates as I pile on more kilometers.
