rwdpwr

hey guys, i have a 1jz auto. Today i was driving around for the first time and the car would not shift into 4th gear only 3rd and when i put it on o/d it downshifts to 2nd. Also when i tried to park i put the car into reverse but it will not shift into reverse anymore. any ideas? i want a r154 sooo bad now...
ps. when car is shifted into neutral it will not roll backwards only foward.
The drive shaft will not turn in the reverse direction i have had it with my car...its like its locked for reverse...
