If the fluid is good and still doesn't hit any gears then take it to a shop , could be solenoids , a computer problem or need a rebuild .
There was some problems with the gear switch and harness, it would show the correct gear on the selector but not the TCM so the computer would not engage the transmission. Any good transmission shop can tell you if it is a transmission or electronics.
