Is it possible to hurt a manual valve body?

I have a pretty straight forward question relating to a turbo action cheetah reverse manual valve body. There was one in a race car we use for road course racing, and the transmssion was stuck in between 2 gears for some of the time, pretty much frying the inside clutches and fluid. I am wondering if the valve body got hurt at all or can you flush it out and still use it? I can't seem to find a good answer. I assume theres no real parts that can get damaged in the valve body since it essential just re-routes fluid?
Thanks for any help

I would think if you cleaned it out and made sure no valves were stuck and the bodies not cracked then it would be good to go.

You might be able to send it to Cheetah for inspection and cleaning. Might be worth a phone call.

Occasionally you'll find valves and/or a casting that is galled or a broken spring.
