After you drive 20-30 miles when you stop then go again it shifts hard. Set for a bit then it drives ok, it comes and goes. Got bearing replacement, swaybar, tie rod ends. That stopped air leaking in front tires but didn't fix problem. The brake fluid is dark and dirty. Never seen that before

It is normal to have the brake fluid look dirty, it means it needs to be flushed please watch this video to show you how.

We should run the codes to see which ones are stored, this will let us know which sensor or module is having an issue, here is a video for that as well.
