So our 2001 Mazda 626 has about 160,000 miles, engine runs well but we are seeing signs of age...

One of the big problems that is starting is that when I put the car in "Drive" I have to pull back on the shifter so it "clicks" into place. I just can't put it into drive anymore. I had a mechanic flush the ATF system and refill with fresh fluid, but it's still happening.

I hope the tranny isn't going out... but are there any other things to check or adjust? Also, the light for the drive gear on the shifter is out...
