I take in a 700R4 from a customer from IL who rebuilt the transmission and was only able to put 20 miles on it before issues began to surface. He asked me to inspect the transmission to determine what when wrong, rebuild it to ensure it lasts and improve it's shifting characteristics.
This video shows what I found upon tearing into the unit.
