Trouble with 93 LX overdrive

[Biffmeistro]

Allrighty. I am the proud owner of a 1993 LX 2.3 Convertible.

But.. there's something I find peculiar with my transmission. I have the 4 speed auto, but I can only feel 3 gears.

I set it into overdrive, and pull out, it shifts at about 15mph, then it shifts again at about 45 or so, then it stays in that gear. Even if I bring it up to 85, 90 miles an hour, I can't feel any shift into a 4th gear.

I asked the techs at the ford dealership and they claimed that it just shifts out of first very quickly. Does it actually shift into third gear at 15 mph?

Is there anything wrong with my car, or am I just an idjit?

What do the rpms run at highway speeds? If you are running about 3000rpm at 78mph, then you have 4 working gears. if it is closer to 4000, then you arn't getting to overdrive.

I usually run somewhere 3000 for 65 to 70 or so.
So it seems I'm not getting into overdrive.

Yep 3000 at 65 is NOT in OD (I have a very flakey OD so I watch the tach constantly) 2500 rpms for me in OD is about 68
