i have a 05 LGT with the 5EAT tranny.
when it's cold it "kicks"hard into 2nd and 3rd gears while up-shifting. once the tranny warms up it's not a noticeable. when it shifts hard, it also makes a "clunk/ bang" noise. this also happens when down shifting into 1st, at any and all temps.
i've got 45k on it and will plan on dropping the tranny pan and then refilling with what ever oil i'm supposed to use.
do you think it's just in need of a fluid change, or could it be a mount/ bushing?
