I run a trans-go shift kit in my 1971 727. Had it now for 9 years. Manually shift all the time. Shifts as good today as it did 9 years ago.
That kit addresses some of the issues that cause wear in a stocker.

PS, if it's so hard on the transmission, why did Ma Morpar make it possible to manually shift from low to drive, and drive to low?
The intent of being able to manually shift and hold certain gears is to delay shifting on a hard pull and/or for compression braking in the hills.

Back when I was a kid, we manually shifted them things all the time. I don't remember anyone having transmission troubles.
Again, it's about "occasional" versus "frequent".

Do a little experiment...jack the rear wheels clear of the ground, warm up the trans, place the shifter in "1", run the rpms up to 1500 and manually shift to "2". Don't be surprised if you see the rear wheels come to a momentary stop as the trans shifts to 2nd; this illustrates how much overlap there is when manually shifting 1-2. This overlap causes wear on the band, that's why it's not applied in 1st when in Drive.
Don't believe what I'm saying? Go to page 173 in Carl Munroe's 727 book and he'll say the same thing.

Lemme tell you about my uncle Bunnion, smoked unfiltered cigarettes and chewed snoose until the day he died at age 93. Proof positive that smoking and chewing don't cause any problems.

Guys, John has told you why its a problem and that its not a big deal, but will lead to the trans wearing out faster. He explained it well and backs it up with references to the exact page in a book that most of us have. How does anybody know if manual sifting shortened the life of their trans or not? There is no standard to compare it to, some stock trans trans go 140K miles before needing to rebuild, some go 60K. This is kind of like fighting over how many angels can dance on the head of a pin.  John's answers are well thought out and back-up, he's only sharing his knowledge.

I under stand what John is saying on the add wear and tear to it I also drive them like stumpy,if not harder I have had a lot of jy stockers last yrs and I have went through 4-5 in a yr so my ? is...if you are drag racing with a more or less "stock" 727/904 auto instead of putting it in 1st on launch,put it in 2nd on the colum and then launch and let it do the wot 1-2 shift on its own,then do the 2-3 shift manualy would that be any better? less wear on the bands?

With an automatic valve body, launching in any gear but "1" places all of the strain on the overrunning clutch (sprag) which is a known weak link in the TF, that's why it's not recommended. In "1" the rear band is applied and takes some of the strain off of the sprag. Of course, any second now someone will pop up and declare "I been launchin' in 2nd for xx years and never had a probem". I can only advise.
The best setup is a billet rear servo piston and heavy return spring/retainer, there will still be some overlap on the 1-2 upshift but not nearly as much as with the factory parts.

Stock carburetor or aftermarket? If aftermarket does it have the correct Mopar throttle lever adapter?
Assuming the carb is correct, late shifts are usually a result of improperly adjusted TP linkage...shorten the top rod to make is shift sooner.
