I have a 93 GMC 2500 truck to which does the same thing that I haven't figture out yet,but since your is new then mine you may a a shifting solenoid
that shifts from 3-4 or 2-3 and then 3-4 I am searching to see if my 4L80E
tranny does have this too but haven't found any thing out yet.
But you will have to drop the pan to
change them out though just as I have done on the 1-2 & 2-3 plus the TCC one
I am trying to find out if the last large one is a 3-4 or what is its purpose. This is all I can offer you in help
