clear codes first
12.4v - 12.8 v at the battery with everything off.
13v - 15 v running with no accessories on.
read codes after. pay attention if its current/not current. and if there is any systoms codes with it
common issue parts are always on backorder. seen them brand new outta the box with rust on them. so have to reorder and wait for a good one. get the TCM reprogram done and install the cooler line check ball delete box that likes to stick in hot temps and over heat the trans.
Dont go by the torque spec crank down on them as tight as you can. be sure to hold on to the bolt head so you dont tweak the alignment. your gonna bend the mounts but thats what a gm tech told me.
keep me posted bud hope this fixes it
anyone else having a cluck at complete stops, drive to reverse, turning, over bumps, slow speeds.
