Yes I will when I get back to the shop in the morning.

>> Hello all,
>> i have a new job here on a 2016 grand garavan 62te.  i do these transmission fairly regular and have great success.  This is a new job that i have not worked on yet, but i am trying to wrap my mind around the theory of what i am feeling (customer complaint) on my diagnoses.  I have a cost down hard bump that seems to be doing something with the converter at around 38 mph.  I do feel an unusual lock up engagement also, but not near as bad as the unlock i am suspecting.  I am confident that the transmission is at the early stages of a converter failure, but i am trying to school myself on what is going on before i pull to rebuild.  I am including a screen shot of shop stream data that shows the converter slip going deeply negative when i feel this bump.  Anyone can explain the mechanical theory behind what i am seeing?  the vehicle has not set any codes yet.
