when the transmission was slipping and shuddering, they found the fluid was dark

What is your question?

Had a factory rebuilt put in and same slipping ocured after 2 weeks. Said the radiator was leaking into the transmission causing a whitish pinky color to the fluid. So have put in a new radiator and flushed the fluids. Will this car recover and run for years or should I sell it since the repair man was not sure if other parts could be affected.
