Red fluid on the ground plus no reverse...sounds like a transmission issue. The red fluid is very likely transmission fluid that has leaked out either past a seal or gasket. Did you have a transmission fluid service at your last maintenance visit? I would say the chances your concern is related to maintenance performed is small.
