transmission problems, overfull fluid?
hello, i had my transmission fluid changed on thursday in North Ohio, I drove down towards North Carolina, but broke down in West Virginia, about 350 miles from where i had my truck serviced. the vehicle ran fine, then all of the sudden, i was driving up a hill, and it felt like it went into neutral and would no longer change gears. i let the vehicle sit for about an hr and tried again, but had no luck, it would shift into first and reverse, but would return to neutral after about 20 yards. I checked the trans fluid, and it was about 2 qts over filled. Is there anyway that this could have caused my transmission to act this way, is there an easy fix or is this a serious problem, or would there be something else that may have happened to cause this problem
