My local repair shop did some seal work on my '92 100's slushbox about 2 months ago. Spotted some tranny fluid on the garage floor last week, so I took it back. Turns out they used the tranny dipstick for a V8, and overfilled the tranny. I drove it like this for about 2 months. Could this have done any damage to the tranny in any way? TIA.
