TSB#: 21-006-01
NOTE :THIS BULLETIN APPLIES TO ALL VEHICLES EQUIPPED WITH CHRYSLER
AUTOMATIC TRANSMISSIONS EXCEPT 1999 AND EARLIER MINIVANS.
DISCUSSION:
A new transmission fluid (ATF+4(R) - Type 9602) has been developed and
is being used as factory fill for all vehicles with Chrysler automatic
transmissions. Until now, vehicles originally filled with ATF+2 or ATF+3
were to be serviced with ATF+3. Effective immediately, it is recommended
that all vehicles with Chrysler automatic transmissions except for 1999
and earlier minivans be serviced with ATF+4(R). ATF+3 should continue to
be used for 1999 and earlier minivans because of the potential for
torque converter shudder during break in. For all other applications the
ATF+4(R) fluid offers significant benefits as outlined below.
NOTE :ATF+4(R) MUST ALWAYS BE USED IN VEHICLES THAT WERE ORIGINALLY
FILLED WITH ATF+4(R).
NOTE :SERVICE INTERVALS DO NOT CHANGE. THE SERVICE INTERVAL CURRENTLY IN
EFFECT FOR A GIVEN VEHICLE SHOULD CONTINUE TO BE FOLLOWED.
NOTE :ATF+4(R) IS COMPATIBLE WITH ATF+3 AND CAN BE USED TO TOP OFF
VEHICLES THAT CURRENTLY HAVE ATF+2 OR ATF+3. DO NOT USE ATF+2 OR ATF+3
TO TOP OFF VEHICLES THAT HAVE ATF+4(R) FLUID.
BENEFITS
^ Better anti-wear properties
^ Improved rust/corrosion prevention
^ Controls oxidation
^ Eliminates deposits
^ Controls friction
^ Retains anti-foaming properties
^ Superior properties for low temperature operation

Subject: DML: RE: ATF +3
I just went through all of this just recently with my multispeed
(45rfe). I'm assuming your's is a '00, because in '01 they went to
ATF+4. According to the Dodge shops I spoke to, ATF+3 is still the
fluid to use if your tranny originally calls for it and all you're doing
is changeing the filters(there's 2 filters in the 45rfe) and approx 6
quarts of fluid that comes out with them. ATF+4 is a synthetic fluid
that is used in most Chrysler trannys from '01 and up. The idea is to
lower tranny temp and extend service intervals. If your tranny calls
for ATF+4, then stick with that. You can use ATF+4 in a tranny that
calls for ATF+3, but unless you're getting the full flush service, where
they completely flush all of the approx. 14 quarts of fluid from the
tranny and converter, then you're wasting your money and will get no
added benefit. I finally just changed my fluid and filters on my '00
Quad Cab with 38K miles just the other day. I tow a car trailer with it
alot and figured it would look pretty dirty. You know, the tranny and
fluid were absolutlely clean!! Very minimal filings on the magnet. I
guess there's an advantage to not having bands in the transmission. Al
