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.
