Bro , I have a question , AS You said there is no harm changing gears except high speed ,so i want to ask that ,some days ago ,i was coming from Islamabad to lahore via motor way ,one of xli geek ,many times tried to tease me ,then i started racing with him ,i was driving my car at 'D' gear , at the top speed of 165km/h , his xli was very parallel to my car , then suddenly i thought ,i may convert gear ''D'' TO ''S'' .,Then i may get a little more from this car .but suddenly i felt a little jerk ,and car didn't get any more speed , Balky i felt thori kam speed par ho gaye . then i again switched it to 'D' .
Now my question is , was it Okay with car transmission ? or some thing we have to learn more ..
Thanks for bearing us , and sharing experiences
