im not a trans expert but maybe something in valve body is sticking when metal heats up? also fluid viscosity changes when heated, gets thinner, less hydraulic pressure with worn trans parts. valve body may also have small leak that is worse with hot fluid causing loss of pressure. also make sure external down shift arm is working.
