Re: what is it

they are the same thing. You need to make sure if its for a V6 or V8 though. Can't interchange them.

Re: what is it

for that price, i wouldn't trust it to last long, you need to know if its a 4l60 or a 700r4, because the later 4l60's are computer controlled

93 or 94 + i believe, and depending on the year, it may have different input splines, 27 or 30, and they are different between v6 and v8 cars
