Mixed tranny fluid
93 dodge caravan 3.3 l
i checked tyranny fluid : It was at the bottom tip of dip stick so i grabbed a qt of dextron 3 and filled to half way
( engine running, hot, in neutral)
i used the whole qt
then i realized that it should have been atf +4
(which was the original fluid) ( 4 qt total )
note: No idea why it was low..
(last check was about 3 months)
no leaks, runs great ????
Lots of slow stop and go (daily)
maybe overheated??
So, now what??
1.0 fill to top with atf +4
2.0 replace fluid with atf +4
or...????????

Is it an electronic transmission A604?
1 qt may not be that bad but you can pump a fair amount of fluid out of the transmission and replace it by putting a suction hose down the dipstick tube, thus diluting the Dexron 3.

In testing done during development of ATF+4, Chrysler noted the following viscosity loss from shearing for the following ATFs (20 hour KRL Shear Test):
Dexron III - 40% loss
Mercon V - 19% loss
Type 7176D - 32% loss
Type 7176E - 14% loss
Type 9602 - 10% loss
You can see what a significant impact the new viscosity improver had on ATF+3 when you compare the 7176D and 7176E numbers. From the standpoint of viscosity loss alone you can see why Dexron III should not be used in transmissions that require ATF+3 or ATF+4. In terms of other basic performance parameters, ATF+3 (7176E) comes the closest to ATF+4, with Ford’s Mercon V a close second. [Which doesn’t mean that Mercon is acceptable.]
