Trans slipping

Last week I purchased a used 94 Thunderbird with 57,700 miles on it. The car is clean and was never in an accident. I purchased it from a new car dealership where I used to work that was a trade in. My best friend is a sales manager there. I had another car that the overdrive just went and got rid of that for this. The Thunderbird looks and drives like new.

Now I purchased it last week and the car was fine. I was off from work for a few days and just drove the car locally. Now I took it to work today and while driving on the highway the trans was slipping in and out of overdrive. It happened about 2 times going to work, on the way home it happened again. I had a Cougar a couple years ago either a 96 or 98 and the trans would always slip in and out of overdrive. The trans on that was replaced twice and still did the same thing. Come to find out it was a module or sensor in or on the trans (I don't remember exactly).

Anyone have a ideas, comments or suggestions of what I can do to fix this. I don't have a problem putting in another trans if I need to but that would be my last resort if possible. With such low miles and paying next to nothing for it, it would be well worth it.

Exclamation Thunderbird tranny?

Well, did you check the tranny fluid (don't forget to check while the transmission is warm & the engine running)? That would be my 1st guess!

Is the Thunderbird a V8? If so, possibly a transmission grommet (I hope I got the name of the part right). Your problem sounds exactly like a problem I had a Crown Victoria some time ago. I took the car to a nationwide transmission place, naturally they told me I needed a new tranny. A friend of mine told me to get a 2nd opinion, so I did. As it turns out, this "grommet" problem was kind of common on 302's w/AT. Go fish?

That was the first thing I did was check the fluid. It is a V6 3.8 liter.
