Don, I publicly apologize to you. And to everyone else, If Don tells you to run Type F in the transmissions he is responsible for, please by all means do so. I was not trying to undermine him.
the iron TF and 727 TF are not that similar. Now the turbo-hydro 400 looks like they tried to copy the iron TF. Mid case support and sprag.
I also agree that the 727 article had some problems and was for setting a 727 up for performance usage. Some things were lost in translation, Even after re-reading.
Where I am coming from is after attending a Gil Younger transmission seminar approximately the mid to late 1990's we were informed 'Type A and Type F were no longer the same that was available even through the 1960's,1970's and to mid 1980's' There wasn't any whale oil, and reserves were exhausted. they mentioned the reformulations Dexron II Mercon II and later sent out recommendations for the Mopar +4. I have used this in everything I own and have built in the last 18-19 Years. Power Flites and Iron A488 Torque Flites, A727, A904, A998 999, A500,40-44 RH/RE, 518 618 47 A818 RH/RE, 48RE, 45RFE, 545RFE Very few transverse.
I inherited a good amount of NOS Power flite and A488 TF parts. I used new paper and rubber when I could find it. Not real happy with a company that repackaged dried out seal antique rubber. I am sur Don Know's who. All my old NOS clutches and bands have survive so far. Yes I even used the old two part cork and friction clutches. Knock on wood. All with Mopar +4 and added Cooling line transmission filters from the 1960's push-button models, being they come with a repair kit that makes installing them a breeze, even on Iron. I will be responsible for my transmissions. and Don for his.

The 727 and the cast iron TF have nothing in common. I still recommend type F if it is available, but Dexron III or Mercon is OK too. I use it in my cars because it is cheaper and easier to fine. I have had no issues with it. I don’t know why anyone would
recommend ATF-4 in an old trans. It is for later computer controlled transmissions, and is probably not compatible with the clutch and band material in the old units. The Hot Rod article also had some blatant errors to a trans guy. It was all about hot rodding
a 727, most of which is not needed on a street car.

Since the HotRod article specifically addresses the 727 transmission, I'm not sure their fluid recommendation would apply to the earlier 488 cast-iron TorqueFlite in my 1957 300. My transmission was rebuilt by 300 Club TorqueFlite Guru Don Verity, who
recommended Type F for that transmission, and I'm sure he was aware of the ATF+4 fluid when he rebuilt it a couple of years ago. There was also a thread regarding the thermal stability superiority of the new synthetic fluids, but raising the possible incompatibility
with old-formulation seals, leading to leakage, so I was reluctant to experiment! The Type F seems to be working OK now, although it puked at least a quart out the dipstick tube after driving only 20 miles (initial overfill?) but has settled down after that.
I barely have 200 miles on it yet.
