When I recently swapped a 2004R back into my 85 SS I can no longer can get the shifter into gear 1 or 2.  D, OD, R, and P are fine, the shifter just doesn;t go far enough back to get into 2 or 1.  It had a TH350 in it that someone else installed before I put in the 2004R.  It is not something totally necessary but it is starting to bug me.  Is this adjustable?  if so how do I adjust it?
Thanks in advance
