What is the essential difference between Chrysler Auto Transmission Fluid 7???
something and Dextron II or Dextron III. My manual says to use Chrysler
transmission fluid only, while the shop repair manual says, Dextron II or III
is ok to use if Chrysler tranny fluid is not available.

I can't find the Chrysler type from regular brand names, I guess I will have to
go to Chrysler to get that.

According to my dealer, the difference is in the viscosity, and it most
likely will lead to eventual problems with your transmission if you use
something else. The shop manual probably infers that its better to add some
in a pinch than let it run with low fluid.
I made a luggage tag sticker for my dipstick that reads "Type 7176 only" You
would be surprised how many mechanics aren't aware of the special fluid.

Chrysler Fluid is already dextron 11/111 just bottled Buy one of the major
manufacturers in Mopar packaging. Type F has more grit and works excellent in
modified 727s and 904s for firmer shifts it was originally for Fords to their
specks (helped their sloppy Trannys Shift) it can also be bought in Mopar Cans
Your dealers telling you your tranny will fail with any other brands are
assholes (Chryslers is the other Brands). I use mopar type f because i get the
best price on it at my local dealers parts Dept. A dog with a wool jacket is
still a dog. Go to a Exxon refinery and see all the different labels and cans
filling out of same tanks.

If a car calls for dextron 111 its still dextron 111 whether its Mopar or exxon/esso,
Quaker state ect. Blaming the fluid was an excuse for the early crappy overdrives
failing ( north american customer service its always the customers fault if we can
weasel out) most of these things blew up with nothing but mother mopar labeled
products.
Barry Lee ( I'll only drive Chrysler products but the Japanese know customer service.
yes Sir we'll fix it right away, not, its your fault warranty probably won't cover
it.)

False. We are discussing Chrysler ATF+ (now ATF+3) Type 7176, which is
NOT the same as Dexron, Dexron II, Dexron III or Dexron IV. It's also not
the same as Type F, and it's also not the same as ATF+4, which is used in
'99 and newer Chrysler product automatics. '89 to '98 Chrysler product
automatics call for ATF+ (replaced by +2, replaced by +3) type 7176, and
that is the fluid that needs to be used.

> manufacturers in Mopar packaging. Type F has more grit and works excellent

Type F has no "grit", neither does any other transmission fluid.

It's not a question of "other brands". It's a question of "other
specifications". ATF+3 Type 7176 can be purchased from MoPar, from
Pennzoil, from Shell, from Quaker State, from Mobil...but it STILL isn't
the same as Dexron-anything or Type F.

Each type of auto trans fluid (i.e., "A", "F", "DEXRON II, IIE, III)
stands for a specific fulid spec--not just some fancy trade name as some
might believe. The differences can be viscosity, additive packages,
etc. For non-elecronic controlled 727/904/999 TorqueFlites, they
started with Type A and progressed up to the Dexron variations. The
police car book on Chrysler products says the Calif HP used 20w motor
oil in theirs wih no problems (although the other GM and Ford trans did
have problems).

The orig Type F fluid had a more agressive intiial friction property
that let Ford use less clutch plates in the clutch packs to get the same
smooth shift feel that GM did with more clutch packs and a less
agressive initial friction characteristic DEXRON fluid spec. That's why
Type F fluid made GM auto transmissions shift harder. Ford later
started using DEXRON.

The current DEXRON is DEXRON III and will supercede all previous trans
fluids used in GM cars back to the first HydraMatics (according to
them). It is rated for electronic-controlled trans whereas previous
ones (except IIE) were not.

Our Pennzoil rep verifies the differences in the various fluid specs.
If Chry/Ford/GM say to use a particular fluid spec AT fluid, just do it.
The Type F substitute for DEXRON may be acceptable, but in a FWD drive
transaxle, you will be better off using the factory spec fluid and the
only real way of getting the best factory spec fluid is from the dealer.
You may go to refinery and see the various cans for various companies
there, but each of those batches is "built to spec" for each of their
customers and may not be quite as generic as many people believe. Just
because Valvoline may build oil for Chry doesn't mean it is the same as
what they sell under their own label. They Chry oil will be built to
Chry specs because they are paying for it and it is their reputation on
that can, not the people who put it in the can.

Must not have too good parts stores near you , Texaco Havoline ,
Quaker State , and Citgo all make CC 7176 type fluid replacements and
they run about $1.79 a quart around here , don't know what the dealer
gets.

I believe that what we are talking about being imperative oil choice refers to the
604/41TE tranny's, not the old 904/727s.
It has been well documented that the wrong oil choice in the
overdrive/frontwheeldrive trannies causes shifting problems and shortens equipment
life.

yes-- I have a 89 grand voy and I have done a lot of research on the probem
and by all means change the fluid to 7176. You can take it to a
garage/dealer and have them do it or you can do it yourself but it is messy.
It will also take several fluid changes to get all of the new morpar 7176
into the trans. You can only drain apprx. 4.5 quarts out at a time in that
the torq. converter holds about 4 quarts and this will not drain out so you
must have the fluid changed several times to get the dextron out of the
system and replaced by the 7176.

To do it yourself, on a level surface block the wheels, set the parking
brake and jack up the front of the van. Block up under the van for safty.
With a large box and plastic liner or some other suitable container place it
under the bottom of the trans pan. remove the 10+ 10mm bolts and the fluid
will drain out. Once the pan is removed you can view the trans filter pull
this off and replace it (the filter is kind of hard to get off but you
should be able to get it off using just your hands).

You can get 5 quarts of mopar 7176(dealer only) for about $15 and a Fram
filter and gasket for about $15 from any parts store.

The filter goes on very snug and you must get both of the protruding plastic
nibs pushed/snaped into their recepter holes.

The nice thing about the fram filter is the cork gasket that comes with it
holds the bolts in the pan readiing them for when you put the pan back up to
the trans.

After draining I put 4 quarts in and then start the van and move the shifter
through all the gears and then check the fluid level with the car idling and
I add a little more if needed to get it in the warm area on the trans dip
switch.

Wouldn't it be nice if they would just put a drain plug on the tranny
so that you could just drain it out before pulling the pan . It
certainly would be a lot less messy . I know there must be a reason
for not having one but i can't think of what it might be , they put one
on the oil pan why not the tranny . Maybe they are afraid people would
drain the tranny and think it was the oil pan and then fill with the
wrong oil (just speculation).

The reason it takes several times is that you can't get the fluid out of
the torque converter. I have heard that, perhaps, Snap-On, ois now
making a machine that is sold to garages that will allow complete change
of the fluid. It hooks up to the transmission cooler line and pushes
though the torque converter. the filter still needs to be changed
afterward.

Ask around to find out if anyone near you has one of these.

Yeah I read this too that Penske has the tranny fluid flushing
equipment , if fact I saw them advertising this fact just a few weeks
ago.
