I got 15 Corolla L with 4 speed and having some transmission problem.  going highway speed and at 4th gear and I step on the gas to speed up and I have to press deep for my transmission to act, my transmission clunks/bangs in to gear hard thought my transmission was gonna crack it's that hard and bad.  Anyone with similar issue? suggestions? only happens from 4th to 3rd.
