Hello all, I am new to the forum, been searching online for what could be wrong with my wife's 2002 Dodge Intrepid, and came across this wonderful site!
The car has been driving fine, it has around 90xxx miles on it...All of a sudden a few days ago, the heat stopped working in the car...No big deal, I noticed the coolant, so I put some Peak 50/50 Global Lifetime Pre-diluted antifreeze in. The heat issue was fixed, and started blowing hot again...
Fast forward to about 10 miles of driving after the coolant was added, the car made a jolt like it couldn't shift, and when going 40mph the RPMs were between 4 and 5...Parked the car overnight, figured I would look at it in the morning.
Morning comes, start the car, and lights still there. Turn car off, and I loosen the cap off the coolant, while the engine is cold, and put it back on tightly. Start car, engine light is gone! GREAT!
Drive it about ~50 miles, and it does the famous jerk and not shift, high RPMS.
Had the engine light codes read, P0700 and P1776. Also, let me add the coolant level is low again (below minimum) and the heat has stopped working.
What could be the issue here? Any insight?
THANKS IN ADVANCE!
