Thanks! That was the problem with my shifter, it was not aligned correctly. Unfortunately it didn't fix my other problem with it going into reverse, and the whining is still there. I done some research last night, and I think I have a broken Sun Shield? I think that's what the guy called it.
Anyway, what he described is EXACTLY the problem I had. I accelrated, and I heard a really loud "clunk" from underneath the truck, and the engine reved up really high, like it was in neutral, and it made a whining sound. When I got the truck back home, I noticed that I no longer had Reverse, and they said that Reverse is the first thing to go out when you break a Sun Shield, and eventually, you will lose all of your forward gears as well.
I was hoping that the problem wasn't in Tranny, as it's almost impossible to find someone around my area in WV, that rebuilds them. So I'm likely going to be stuck with going to a garage and having them look at it, to make sure of the problem, and then ill probably have to have a new Tranny put in
