It's probably the front brake solenoid on your valve body. It could just be bad and you just need to replace it which is easy once the valve body is off, or the band inside your TCM is broken or came unsoldered. Either way you need to remove your valve body to get to it. Once you drain the fluid and remove the pan it doesn't take long. There are several bolts holding the valve body on but you only have to remove 12 to drop it. Careful not to let it fall there are 2 wire harnesses you need to unplug. It's best to have an extra hand if possible to hold it while you unclip the wires. I did it by myself but had some trouble holding it up while I unplugged the harness. After it's out there are ways to check the output of the solenoid. Or you can take the TCM off the valve body and open it up to look at the bands inside to see if one is broken or came unsoldered. Mine had a broken band that went to the solenoid. I just re-soldered mine and didn't have any more issues. But if you don't want to risk doing it yourself and taking the chance of it coming off again you can just buy a new TCM unit and replace the whole thing. Either way it's a lot cheaper than a new valve body or transmission.
