I have a 97 Cherokee 4.0 2wd. Everything works on the car except overdrive only works now and then. and the check engine light is on. I had it scanned for codes and the 2 codes it threw up were p0700 and p0705. What should i do? Back story on the jeep i just got it from my cousin for 700 and it was sitting under a tree for nearly 2 yrs. we already replaced the entire cooling system and flushed it thoroughly . it only had 147000 and i am the second owner
