Transmission trouble

I have a mazda 626 with a hard 1-2 shift. All other gears shift smoothly and they all shift when they are supposed to. There is no slipping, just the hard shift. I had the fluid flushed but the problem remains. Am I doing damage continuing to drive this way and would you think it would be an expensive fix. The tranny is a cd4e ford transmission. THX

What year is your Mazda?


It is a 2000 626 with 60k miles
