Service Four Wheel Drive message.
This weekend, I changed the front & rear axle fluid and the transfer case fluid. This morning, I tried to get into low four wheel drive, and the 'Service Four Wheel Drive' message came on and it won't go into low 4-WD.
This is a 2006 Commander with 4.7 V-8 engine. It has 49,000 miles on it.
I installed two quarts of NV-245 fluid into the transfer case. The rear end took about 2 quarts of fluid, and front axle a little over a quart to fill.
What could have happened by just changing fluids to have this happen? This is the second time I've changed these fluids.
