Tranny Might Be Going Out

[goXtreme]

On my 08 F-250 work truck, I think that the auto trans is going out:

In all forward gears it works fine, just like it is supposed to, put it in reverse and it will slip and grab, slip and grab the whole time I am backing up.

The truck has 43K miles on it and is going to the doctor this morning, will let you know what they find

What was the solution to this problem?

There was a bad O-ring in there that was not doing its job, I guess, it has been working fine since then, I now have 82,000 (and change) miles on it with no problems
