The Oakite solution that was once used in hot tanks is illegal these days due to "environmental" panic. The greenies will trump up huge fines for anyone who tries to use any sort of an effective hot tank cleaner, so those tanks have been replaced by industrial strength motorized pressure washers that use something resembling commercial dishwasher detergent. The trans would have to be completely dismantled to benefit from that kind of cleaning.

Oakite and similar caustic hot tank chemicals would eat the brass and bronze parts of the transmission, even if you could find someone who still operates a hot tank illegally.
