i think that i know this means my tranny is about to go anytime when my O/D light starts to blink. it just started last night during normal driving so anyone have any suggestions on what i should do?

Yeah start saving up money or take out a small personal loan.

besides that

 do a drain and fill on your tranny fluid and then reset the computer and see if that takes care of I did that to mine and it has not came back on since then

It might not have anything to do with the fluid being changed. If you reset the computer, the code will not come back on for quite a few miles after the computer is reset

what will the dealer tell me if i take it in for them to look at?

You need to go and buy a shift selonoid block assembly that is located right under the pan on the front of the tranny. It ranges from $125-$175 and is a snap to put on.

what is this and what does it do i have never heard of it before. thanks. -ben

The shift selonoid block assembly is an aluminum block with switches and god knows what in it. It makes the tranny shift, it has a 1st,2nd,3rd,4th and converter lockout selonoid all together. You can look at the top of the tranny towards the front and the bundle of wires going into it is the wires for the selenoids. It's easy to install, go to NAPA (the only place i found it other than ford) and get them to find it for you and order a pan gasket. It takes about an hour to install and its very, very easy. I put one in mine and got 14,000 more miles out of my tranny but it finally went "kaput" at 118,000 miles for me.
