i got a 99 toyota camry and the speed sensor went out and then two day later im driving and i herd a couple loud bangs for the transmission and it started smoking got home jacked it up and trans oil i pouring out at the end of the tranny next to the motor and there was a few metal shards and a few big chunks coming out and i can let it cool and crank it back and put it in P,R,N,D and as long as i hold the brake and dont move the car it wont leak but as soon as i start driving it starts pouring trans oil out! i need to no what it is and if i could of messed my transmission up!Thanks!

 

seem complicated to me...I suggest go to expert mechanic for that, it seem to be the transmission but I'm not sure.
