i posted on here before about this but now it is doing it all the time. if you push just a little harder than normal in ANY gear my whole shift pattern changes to farther up, like normally 1 3 6 are about half way- after you shift a little harder than a granny it moves all the way to the upper part of the shifter side. this is all gears, they all shift up about 2 inches. This showed up after the dealership put in a rebuilt transmission due to my last one crapping out. I took it back to them and they said no problems? Any ideas?

 

sounds like your synchros are going... take it back to the dealership and have them rebuild it again..haha.
