just curious because i just ordered a 3800 stall, 10in, lockup JW for my car with a 700R4. my Yank just took a dump and i didnt want to go with another one of those for a grand. i got this because my friend who had a 9 second LS1 told me about them and all his buddies from the track run them and love them. said they've never seen one fail either. only $500 so i figured what the hell ill try it.
