i had posted this before under "transmission shudders". anyway, after my recent tranny service about 800 miles ago, i noticed that the shifts were harder. the 3-4 shift in particular is harsh particularly at lower engine speeds. i would characterize it as a slight shudder. the fluid i used was valvoline semi-synthetic. while i am wary of synthetics and leaks, i decided to give it a try with the thought that the synthetic portion would help "clean out" the tranny. i was planning to drain then refill with dino ATF after 12k or so but i may want to do this sooner if i don't get rid of the shudder. i have checked the fluid level and it is correct. will lowering the pressure on the vacuum modulator help? if so, how much should it be turned?

thanks
