ATF +4 for Racing?

Post by Chipped tooth » Wed Oct 29, 2014 8:07 pm

I just had a friend drop off 3 un opened boxes of +4 ATF

Anyone have anything bad to say using it in racing transmissions?

I use it in my tow rig with zero problems.

IMHO it's too slick for racing...................but people run all kinds of trans fluid racing and seem to have success.
I used to be a people person, but people ruined it.

That's sorta what I'm concerned with, I suppose a couple quarts in tractor fluid couldn't hurt....

Old thread but still on the first page
ATF+4 is a full synthetic premium fluid
It has a friction modifier that only really prevents chatter of the converter clutch
converter clutch chatter eventually destroys the converter, which plugs the cooler and bad things happen
NEVER run anything else in a 518 or Later MOPAR trans
as for being too slick
that is compensated for in the valve body or on later trans the computer
Type F will lead to shorter friction life unless you have modified your apply rates
the harder shifts you perceive are not the way you really want them
therefore NO type F and no GM Spec fluid
put in a Transgo big reprogramming kit
developed in 1992 on a local Dodge Dakota and still going strong over 200,000 miles later, trailer towing
