Stephen I have a T-350 ( rebuilt in the past year) and I am eather going to look for an 700R to put in or just get another Torq Converter. Any suggestions? I have 35" and 4:56 gears, most of the time I use mine to haul a Boat or Bikes to shows. If a Torq converter, what rate and what about locking converters?
