Weird transmission "stumble"
Hey guys, I'm starting to worry about this little quirk my '95 Cougar has in its transmission.
At some point between 30-35 mph, my car seems to stumble for a moment. It feels like a quick tap on the brakes, and it seems like the tach usually drops quite a bit. I'm thinking this is just the 2-3 upshift, but it feels very strange. After the stumble, if I hold speed and press the O/D OFF button, it'll stumble again, with the same tapping-the-brakes feeling.
If I'm driving with the O/D off, it doesn't do it. I can't figure out why the overdrive should have anything to do with it.
Anyone got any ideas? This transmission's only about 70,000 miles from its last rebuild, according to the records I got with the car.
