My car symptoms consist of (not always occurring)

Stalling when I come to a stop light

thanks for the response Daniel! To answer your question, I haven't replaced the tranny at all. I will check the speed odometer but thats along the lines of what the mechanic was telling me. I will check on my drive home from work
