Transmissions seems to come out of gear when not under load ie going down hills. Will not find any other gears except for 4 low when this happens. Then I have to put into 4 high, and into drive quickly, and crawl until it engages with a clunk. Once working will change back and forth from auto to 4 high no problem. It will work in all ranges and all gears. Did notice overdrive light flashing at one point.
The only alarm I am getting is Cam shaft position sensor. Could this be related or something different?
Any advise would be greatly appreciated!!!
