98 Seville

I am having problems with this 1998 Seville since the battery went dead. We replaced the battery and ever since then the shifter is almost impossible to move. It keeps flashing the code's No. 84 and 113 and is hard to drive. In the main codes it is saying RSSC1711. If I try to reset it it seems fine overnight only. Any Help would be appreciated to fix this problem.
