I would check the transmission dipstick tube and also see if your downpipe is close to your swaybar as you may have to flip it. This may be different on an impala but I do believe it is the same setup as far as a "rolling chassis" is concerned.


I read that thread about you possibly getting that dhp tuner so if thats the case just decrease the timing in the cell that you are getting the flash kr in and see if it goes away...There are manny things that could cause false kr...the things stated above and even tranny noises
