Running a basically stock 727 behind a stock 440 in a 70 Charger R/T. Old man bought this one new, so it will not see abuse. Thanks all.

"IF YOU'RE UNDER CONTROL, YOU AIN'T GOING FAST ENOUGH."

Seems like rule of thumb is:
High dollar trans, go expensive synthetic, not like you'll have to keep adding unless it leaks.

regular stock type overhaul:name brand Dexron

My .02, years ago I ran across a magnetic in-line filter made in Australia,(in the trans cooler lines) thru NAPA, also had a larger one for power steering.
On some of my cars, I installed thinking you could basically change that one and leave the pan on for awhile?
I also bought 5 gals of pennzoil dexron from amazon free freight to hawaii for $10 less than our garage price here at Oreillys.
Hope this helps,
Case

My original 1972 Chrysler Newport owners manual says Dexron.. I use Dexron/mercon (Dexron III)

Type F

I thought conventional wisdom around here was to use Type F. That's what I've been using, no problems (other than some leakage).

mix any type f or dextron.you wont notice any diff.sure fill with f or fill with dextron,but add quart or 2 here and their averend what

I use the Mopar ATF+ 4. I was a Dodge tech and have tons of that fluid and it works fine for me as I use it in all my cars including my 63. Ron

I asked after dropping $1400 on my PA racing trans and they told me NOT to use any syntho or type "F" Said to use Dextron, so that's what's in it.

mopar atf

You will get many answers .

the original fill was dexron

Type F for me.
