Seems I am finding different charts for engine codes for my 96 Grand Cherokee. It recently started giving me problems not shifting of of 1st and seems it slipping in 2nd and revving up to high RPM;s. When going up a hill it mostly just slips but sometimes letting off the gas it will shift. I just replaced the rear control sensor on the tranny, dropped the pan with new filter. Was only getting 1-# 43 ode before, Now It flashes 4 in a row. Any suggestions on what I need to check or do? Only have 112,000+ miles on this.

12 is that battery have been disconnected, after 50 starts that would go away, 55 is end of codes so you should have a 55 at the end.
