Im fixing to rebuild a 700R4 and was wondering which lock up is the best? I bought the TCI from jegs for $80. Is that lock up any count? For the money saved is why I went with it compaired to $120-$160 for the other brands. Next is are they hard to wire up and when useing them when is it necessary to use the manuel over-ride, should'nt it lock up automatically when cruisen down the highway? Thanks for any help.
