My 95 did this when it reached 98K miles. Yours may be a coil pack problem but mine was worn plugs. I thought it was my tranny too, at first, until my brother rode in the car with me and laughed at it and ask when was the last time I had tuned it up. When I pulled the plugs out I gauged them and found they were at .085
I replaced them along with new wires and that fixed it.
I just replaced my Ignition module recently because of a mis-fire at any and all speeds, engine temp didn't matter. Found no spark on the first coil bank. After replacing the coil it still had no spark on that coil. I replaced the module after that and that fixed it.
I have replaced all my coils packs do to rusted post. The only reason that I found they were rusted was do to a tune up at a later time. So I replaced all of them. The tune up at that time wasn't do to any drive-ability problems, I just didn't want a repeat of what happened before (letting it go to long). I have not had the experience of actually having a bad coil. I found the coils cheapest at Auto Zone for 20.99.
Good luck with it
