Anyone else running the Superchips MPG tune notice this?

[sdamike]

Ever since I installed the superchips MPG tune (milage xs i think they call it) I noticed that the transmission will shift oddly hard, but randomly. I would almost call it slamming into gear. And I drive the truck very gently. It can be very sparce, for example maybe only once every 75 shifts, maybe more maybe less its all random. What i dont like is I did not ever notice this before the tune., Not even one time, this is a new thing after installing the tune. Anyone else notice this or is it just my truck?

Cant say for the power dept. since im running the MPG tune which is just for better gas milage but it seems to have helped between 1 to 2 Mpg

The Mileage tune on SC is very impressive on performance when wanted(WOT) and mpg when driving easy and carefully gentle.

Never noticed the shifts your speaking of. I downloaded the transmission shift tuning and personalized it to my liking.

I've been running mine on the MPG tune and I haven't noticed that at all. Maybe you should try playing with the tranny settings a bit.
