Default Odd Trans problem

Trans has 2 month old torque converter.
drove car a somwthing from road kicked up after Helene and hit my high pressure line causing it to hit 230f on the way home. Fix line drive it next day, struggles to past 2nd. Drive home struggles to pass 1st. Stop at light lose 1st. Park car, has no gears exept Park. Come back next day car moves 1st 2nd D/OD and reverse. Turn it off to hear friend on phone. Get in car now no gears.

I didnt see anythink electric for the transmission on the schematics. I know the 700r4 is hydraulic so the valves arent powered right? That or my pump is bad and now sitting fluid gets used by opening valve and once trying to use vehicle again it has no more fluid to pull. Im active duty I dont have too much time to work on it and im about to deploy. Id like to be able to attack a specific objective when looking at the car as to not waste precious family time. Has anyone had this problem before? Is it internal or is there an electric possibility I am unaware of?

1988 corvette automatic.

First thing, check fluid level.

You're a bit short on details. Such as, when the line went bad, did it pump out all the fluid? If it did, you may have wiped the pump. To check, you need to get a gauge on the line port and see if the pump is building pressure.
