2006 Ford E-Series

We have had this van in our fleet for a very long time.. has always had its oil changes and regular maintenance.. but that being said the drive line snapped and we got it repaired, but now it has no reverse.. no idea why.. could be a transmission issue could be something more simple, I do not know! I do know other then revers it drives well.. we drove it here from the auto repair place and we have driven it since.. and other then no reverse it drives just fine.. we are just moving past it
