Hi, I have a new 2004 Trailblazer, 900 miles on it. It shifts kinda hard into drive & reverse. I had a local mechanic look at this and he said you need to break it in. I'm not sure about this, I think the shifting should be smooth with little bucking. is there truly a break-in period and how much does the cold effect the shifting? Thanks in advance... Tonu
