After much searching, I think I finally found my car. It's got a 700r4 transmission in it, which the owner/builder says was built by someone named "Tranny John." That's all the info he has on the transmission builder. I just want to make sure that this is a legit transmission builder, and not some story being made up, or some 19 year old kid playing with his dad's tools in the basement. Any info would be appreciated, as I can find virtually nothing on the 'net.

Thanks!
