Running a 727 pro trans, need to change the fluid, what recommendations as to best brand to use? I’ve been using amsoil super shift, type f, and, only a quart left from last batch. All insights gratefully accepted. Thanks in advance. Dave ss/ea #1355

Per Dave Smith " you have the trick tranny, you don't need the trick fluid. I use a brand name type F and change it every 15 to 20 runs. Good Luck....Jim

Valvoline Type F non synthetic
If it starts to turn color or smell change it
Is this car a Street Hemi or M.W. car?
Stock type street and strip Pro Trans or one of his all out his race parts tranny?
Do you monitor and record tranny fluid temps?
If so once it gets near(290+F) or above 300F I change it in my S/P car with a glide in it

Petroleum Type F or FA. Valvoline. Change it frequently.

I've heard of all kinds of fluid being used in the big horsepower units - Pro Mod, RVW, Pro 275, etc - hydraulic oil, shock oil, compressor oil....

I recommend LAT tranny oil...

JR1 synthetic. Changed once a year at about 100 passes
Been running the same band and aluminum drum for over 500 passes. Both look like new. Clutch life is great. Motor makes around 900.

I have had the best results with Penzoil type F non synthetic in my Proflite. SS/BM

We used just about everything in our 727 over the years.

Store brand type F
Name brand type F
Dex/Merc
Universal trans fluid
TCI full synthetic
ATI 20W full synthetic
JD hydraulic fluid

Changed fluid and filter at the start of each season

And the list goes on. We put about 150 runs on a trans per season. The last 727 we ran for 6 seasons and it finally started to show signs of needing a rebuild (900 passes) We had all the good parts in it though. Billet steel drum, lightened sun shell, 2.10 straight cut gear set. roller bearings etc, etc, etc....

I guess my point is that the trans cared less about the type of fluid than it did about the quality of the parts and proper set up.

We use ATi20W in the Vettes Proflite

I used to use Mobil 1 Synthetic but for the past 10 years per the advise from my tranny builder I've been running O'Reilly's type F and every freshen up looks perfect. Told me to quit wasting my money. Run the whole year on same fluid, don't change engine oil all year either.

Been running Dextron since the mid 80's. The trans was in my cuda from 2001-2006. The car was nothing special ran low tens. The trans sat for about 8 yrs when life got in the way. In 2013 took it in to be checked and rebuilt if nec was told other than a few minor adjustments everything was fine. Been running it ever since in my wagon. Its not as fast but is a heavy pig. Nothing but routine fluid changes.

Call Dave and ask him what they recommend now for your deal ,661-940-7400

Ow there’s a man that’s smart

Wade do you have aluminum drums?
Thanks,
Bill

No, Steel billet drums in both my PG and 727.

Dave told me to run Type F fluid in my ProFlite so I use Amalie Type F.

How often did he tell you to change it?
Do you have aluminum drums?

With aluminum drums he use to say change it every 25 runs
That is the main reason to think about buying and using a aluminum drum with a steel sleeve over the outside for the band to seat against

I hate to say this because I am probably an idiot , but I run aluminum drums and I haven't changed my fluid in 25 years. And for at least the first 1/2 of those I raced every weekend.
