Originally it had a turbo 350 but it has been switched to a 400 which has a reverse shift pattern, no reverse bands, and a 3500 stall converter. The shifter is just a B&M ratchet shifter. I did not personally put the shifter in but from my understanding it is pretty straight forward. Bolt in run cable for linkage. I'm not much for the automatic so I plan on changing it out to either a 4 or 6 speed whenever I get out of college if it ever happens.Was this a Manual or Automatic? And did you put in the shift kit?
