First of all please accept my apologies for not replying past few days. I was out of internet for sometime.
Actually I am using my car for last four years. When I took my car to the agents for the service, the mechanic told me that my radiator supports for auto gear. I definitely know that the radiator hasn't change because I bought this car at the millage of 12,000 from a friend of mine who got the car brand new from A*W. So I felt that these cars must be equipped with the basic framework for auto gear. As 'jdnet' mentioned I may have to look around for the required parts and do a proper evaluation before taking final decision. I'll share my experience soon.
