my 4l80 was rebuilt less than a year ago. Ip went out and i quit driving it. while moving it around in the yard noticed no reverse. no pops or nothing. well now i got the ip fixed and figured oh well ill just drive it anyway. Now overdrive is out also. did a band check in low gear and truck still compression breaks so im sure band is good. I think its solenoid or valve body related but not sure any help would be appreciated
