Well driving it with the current issues, your pretty much going
to be rebuilding that unit again
It slips,flairs & has already started to burn the clutches
That could have been prevented IF you stopped using it the
first you noticed something & took it back
Has to come out & be gone thru again
Wasn't built correctly or they never worked on
the electronic area or maybe don't know how to

Are you sure the TV ( trans shift cable at the throttle valve) cable is correctly adjusted?? Without line pressure readings, I can only guess that the D3/Part throttle check ball is missing, if it is a trans problem
If the TV is correct, I am assuming that the TV cable is pulled tight at WOT.
Did you check the throttle (ACCEL) cable to be sure that the carb goes wide open when your accel pedal is on the floor?? This must be done with someone in the car and a second person looking at the carb. Without doing this, you do not know if you have WOT. Without WOT, the trans will not de-tent and shift down.

Have you ever changed the transmission fluid flush and replaced the transmission filter?

Well, first do the service. Pull the pan down and look for metal shavings. If there is metal shavings your in for a transmission. If not, you may have a problem with one of the transmissions shift solenoids located near the valve body.
P.S. The Duramax has the Allison 1000 transmission not the dodge cummins and they are one of the best trannys on the market.

Band adjustment is very sensitive on these units, I set both adjustments at one turn. This is a 4 speed trans that has been converted to a 5 speed by turning on the od unit ( 1-2 shift ) in first gear.the 2-3 shift is busy because the od band is coming off causing the od unit to transfer back to 1:1 and the intermediate band is coming on . I have found that if the overdrive band is to loose it will release to fast causing a flare on the 2-3 shift bot not really affecting the 4-5 (overdrive) shift. So break both band adjustments loose and tighten the adjustment screw down and back off 1 turn the tighten jam nuts. Also the fluid level should be checked with the transmission warm ( 100 f , not hot, not cold) and the fluid should stream out of the check tube. Transgo makes a really nice vb kit that i use that will help these symptoms.
Hello
The engine
and automatic transmission in this vehicles drive train
are fully electronically controlled by a computer called the PCM and
TCM (Power Train Control Module, Transmission Control Module). When a
problem like this or other drive-ability related problems occurs the
computer stores a record of the problem (there are of course some
exceptions to this, like the fuel pump, engine coolant temperature
sensor and MAF sensor for instance) in the form of a fault code in
its memory, to read these fault codes you must have the systems
memory scanned with a special tool. Once the fault code(s) are read
you then must perform the appropriate diagnostic testing to find and
resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL
A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR
HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
Did you flush the grit out of the transmission cooler and the lines to it? If not you may have ruined a new transmission.
