Hey guys-I have the green wrench indicator flashing on a 2010 c2 w/the Mercedes & 2000 Allison trans.It comes on after starting the bus & stays flashing until about 2 miles down the road then shuts off & stays off.I changed the trans. spin on filter so far.The bus drives & shifts just fine.Is there a procedure for reseting this indicator or something else that must be done? Thanks
