I was thinking about putting in a transgo hd-2 kit on my automatic, but some of the shops that I went to say that they are too harsh even at low speeds, when your not shoving your foot in... they say it gets really annoying! Is this true for our cars too?! I want to put it in since I am way past due for a tranny oil change. Has anybody put it on? is it too harsh? this is my daily driver so I do want some comfort .
