i think my t/m is a little different than your guys, cause i have a v-6 mine pushes the truck forward hard. unlike some 5.3 i have rode in it feels like it wants to push the truck forwards really hard but then falls on its face kinda like what you guys are talking about. all the vehicles that i am talkin about have the vette servos in them.

I also turned mine into a "race" Button. Its alot of fun it really shifts hard.
