There is a cooler relief valve built into the transmission case , under the top cover..Once you pull the trans top cover, clean the top of the case where the top cover contacts the case..You will notice a small flat plug in the top surface of the trans case in the front just behind the clutch housing..Pop this plug out and check for gunk in the valve..there's a spring in there too..Once it's all cleaned put it back in and tap that plug back in flush with the surface, Plastic Gasket the trans case top cover back down and try it...

Mine did that too and the "EL" fitting that went into the trans was plugged up and would not take the flow.
It was a pain to get it out but it can be done.
