Just had an accident with my 2005 liberty. It was struck in the left rear. From middle of tail gate to behind rear door was damaged. It was drivable and drove it home .Today started it for the first time since accident. None it has a engine light and a p0700 code coming up. Which is trans related. Could the impact have caused this condition? Any ideas or input would be appreciated . By the way the plastic and body damage is something I may fix with the other's insurance check . But need to get the estimate first .
