i've read one of the GM performance Transmission Gear ratio books, and didnt the TH400 have a 3.08:1 first gear?
i checked with GM about the TH350 we built for my 4x4 and i learned it has a 3.07:1 first, and we did a Lockup Omition or something like that, so we could use a standard Non-Lockup Torque Converter
