Thank goodness for the Trans go kit!! 04 GP started hard shifting recently mainly when going 1-2 and 2-3 shifts but also on an occasion from a dead start had the hesitating bump start,,took it to trans shop just to get it checked and of course it had the po1811 code and was told the usual "replace PCS switch and new valve body" $1200...used the TransGo kit and I cant believe the difference so far, not once has it had any shifting problems ....(but only been a month) of course I am sure posting this will jinx it!
