Sounds to me like the valve body is bleeding off pressure. But I am no expert.

 

Is it possible a throttle cable, lever/spring, adjustment, binding, looseness, and or shift linkage is at fault???? Is it possible the cooler lines were not cleaned/flow tested???
AT this time suggest contact MR CARR for another tranny. Suspect this one is trashed by now. Clutches smoked ect.

 

well they are sending me a new valve body i cleared the tranny lines whith air preshure till no fluid was comeing out as art carr called for and there seems to be no adjustment on the kickdown

 

Adjustment where throttle cable attaches to engine.
