2000 Impala shutters when starting from stop

2000 Impala LS, 3.8L, 118K, when accelerating from a stop, it feels like something stutters, does not appear to be engine. Transmission. Just had the transmission fluid changed over the weekend and it seems to be doing it more often. Also, added Lucas brand shift easy fluid to it at recommendation from mechanic, this was mainly to see if it would get rid of hard shifting that it occasionally does.

I'm having that same problem with my 05, please let us know if you find a fix...

I'm having that same problem with my 05, please let us know if you find a fix...Sounds like your pcs in your tranny,pressure control soilenide,there are lots of posts on here with that problem

Cool thanks... easy fix?

Cool thanks... easy fix?not really,you have to drop the cradle on one side to get the side cover off to replace the soilnide,it's around a $600 job or more depending on where you get it done but bring to someone who has already done one on an impal cause they will know exactly what to do

Thanks for the info... that sucks...
