New guy; question abt hard shifts with 2010 5.3 6sp Silverado?
New to the board here and already have a question!
Just took delivery of a new 2010 Silverado 4wd LTZ w/Z71.
I have noticed that the tranny seems to shift hard when shifting from 1-2. I say it is hard shifting with a noticeable jolt compared to our 2008 Tahoe Z71 (also 4wd). Only real difference is the tranny- 4sp vs the 6sp.
Is this expected? I have no idea what differences there are between the two mechanically other than the obvious 6sp gear-box. Wondering if there are significant changed in the programming involved with the two.
My Silverado's tansmission has "issues"
I have a 2010 Silverado quad Texas Edition with 5.3L and heavy duty 6 speed transmission. It has 4,500 miles on it and has developed a hard shift between 1st and 2nd and when stopping. It clanks terribly at times, but the rough shifting is getting to be almost constant. It's going into the dealer right after Christmas. There are a number of discussions going on at other sites (edmunds.com for example) with people who have 2009-2011's with similar issues. Today mine actually learched forward toward oncoming traffic as I crossed a divided highway and had to stop in the middle. Fortunately my foot was on the brake. This all started a week ago. I am not driving it any more till I can get it into the dealer.
