Hello there!
I have been through a few posts including the 727 transgo tf-2 orifice plug
https://board.moparts.org/ubbthreads/ubbthreads.php/topics/774603/727-transgo-tf-2-orifice-plug.html quite a few times and decided to try post a new one once I would very much appreciate some input from the trans techs concerning a possible 2-3 upshift overlap on my 46RE dodge dakota.
I bought the truck a few years ago in very good condition but the trans had never been touched, I did change the governor pressure solenoid and transducer to resolve a 1-2 shift hunt issue which was noticeable only at low rpm (solved), adjusted bands to factory specs, changed fluid to ATF+4 and filter and also put in a Superior shift kit to preserve the transmission.
The truck always had a very hard 2-3 upshift only at WOT or near WOT, before and after the shift kit, feels like an abnormal bang or bump in the powertrain but only near WOT so I decided to make a restrictor orifice for the direct clutch port. I made it 0.140 inch diameter.
The trans and the truck are in great working condition besides that detail, 66,000 miles now.
My question is, when I previously spoke with the Superior tech representative he told me to loose the front band half turn to get rid of the bump, it helped a bit but the bump is still there, and when I told him I would put in an orifice plug in the direct clutch he said I`d FRY my clutches... I undertand the orifice only slows down the flow of fluid during the shift but after that the amount of fluid that has to pass the orifice will be much smaller and the orifice will not cause restriction in that condition (front clutches applied). Am I correct? Is there any concern or problem the orifice plug could cause? I am going to test the 0.140 inch orifice tomorrow (homemade aluminum plug 0.140 inch shown on picture)

Well thank you for any info concerning this subject,
