Thanks for the input, however I wasn't looking for instructions on how to change the fluid or adjust the modulator. What I wanted to know is if this type of shifting is normal. Is the somewhat sloppy shift an indicator of impending transmission failure? Or is it maybe just something "sticking" which might be cured by running a trans cleaner through there and then flushing/changing the fluid?

Again, it runs and shifts pretty normally except for the slightly softer and longer (i.e. not as "crisp") shift from 3rd to 4th.
