How hard is it to install one of these? I do everythink on my car but I am no expert the only thing I left up to the pros was the short block assembly. The other issue is I don't know what parts are currently in the trans, I do know it was done by Jimmy's transmission, there currently does not seem to be any problems right now it shifts crisp, it has seen mid 11 second passes so far, does lu or non lu converters make a difference, which tb are recomended buy you guys, my current converter is a precision 3200 lu, or should I leave this up to a trans builder, is it any harder than installing a shift kit?
