shifting was always fine for me(never did understand peoples gripes) but,, the creep or take off is drastically improved.(on my 08) much softer or smoother.
makes being in stop and go traffic a million times better..... i used to just click parking brake up a notch. but don't have to anymore.
no so harsh on engagement(clutch) ..
and they put in a different battery (said it was bigger) i never looked if it was physically bigger or just more CCA .. but none the less w/ 16k on it was nice to get a fresh battery .
i hung out. took a few hours and they did this and that.. no charge.
