atf?
 

the dip stick says the mopar fluid or dexon II where is the atf+4 comein from? would the atf+4 mix with the dex fluid? bc i put the dex fluid in the tranni last and i just put my tc in and put the atf4 in the tc and i would need to fill up the pan at least half. so could i use the dex or the atf4 or i have to use all the same fluid? might be dumb question but i heard could mix as long as ones not a synthetic

i highly recommend gettin it flushed with atf 4 but if the dipstick says dex works then u can use that but dont mix them..

where does the atf4 come from where it say that?

X2 on mixing, mixing ATF thats a no no. Because each one has different friction addatives in it. ATF 4 is a better fluid, I would drain it and use just one or the other. Better to be safe than sorry.

ya i put like 4 quarts in the tc of atf4 and have not started it so i can drop the pan and empty it and change the filter

ive been running valvoline max-life for 40k miles with 20k mile service intervals. Its listed to be a full synthetic thats compatible with dex/merc fluids. Its still as tight or tighter than any automatic ive driven.

good info!!!! was going to change fluid and filter on moday and i got atf4 the tranny has only 20'000 on a complete rebuild. so going to call tranny shop and see what they put in it. glad i read this:c:

Still would drop it and only run one type of fluid, My good freind is an automatic guru he was a builder at Certified Transmission, you wouldn't catch him dead mixing ATF in his truck.

why is atf better and used if it dont ask for it?

it has better friction modifiers in it. I know all the newer dodge automatics (03 and newer) come with ATF+4, and thats what is recommended for them. it wont ask for it on a truck built in 94 because ATF+4 didnt exsist yet.
