I just got a 904 trans out of a 85 5th ave. now what should i look for to see if it is a lock up or not? don't want a lock up right. Hey i got the motor to all for a 100.00 bucks and it runs. i have ran 727 all my life don't know crap about a 904. if it is a lock up i am going to go with the 440...
