Sorry to hear that (and SEE that) SSEi95.
I saw some guy in a Jeep at a red before. At the green he must have STOMPED the gas so hard. As soon as he did, I saw something from under the Jeep (A huge metal piece, not sure what it was) break off and fall on the street!
I have a friend with a newer model BMW 300 series. He took off too fast at the red (so I heard) and he caused over $1000 in damage, to something.
I'm glad you found a tranny. I hope when it'* time for me to get a new one that I can find a good one at a good price.
