it's a busted o2 sensor, the other half is still threaded into the exhaust.

could you tell me why my tranny was leaking oil all over the place and i have no reverse if thats possible

[ronburgundy]

that won't be your problem. your trans will either be a 125c/3t40 (3spd) or a 440t4/4t60 (4spd) if it's the 4spd the usual culprit is either a bad reverse servo seal or more likely the drive shell (or stove pipe as we call it) if it's a 3 spd it's most likely the low/reverse clutch or feed tube in the pan. either way it's likely toast unfortunately. no reverse is almost always a major. sorry.

wat is the o2 sensor for ? and why was it hanging ?

[Brandon1992]

i don`t know what the o2 sensor was hanging and they think that it was blown

[Tweaked]

its a oxygen sensor that tells the computer if the engine is burning to rich or lean...
