    I just changed my oil to 10w-30 Mobile 1.

    I was thinking of changing the transmission and transfer case to
    synthetic as well. Anyone else with a Pacifica done the same? Any
    problems? Recomendations?

    If Owners manual states ATF+4 for the trans, stay with ATF+4, or risk
    damage or weird operation like TC shudder not covered under warranty.
    Most, if not all, Chrysler automatic transmissions are designed around

    If the final drive and transfer case use standard 80W or 90W gear oil,
    can't hurt.

    Factory fill in the Pacifica transmission is ATF+4. NEVER use any other
    type fluid unless you want to rebuild the transmission for fun.

    Thanks, Mike...

    Owners Manual says the following:

    Automatic Transmission - Mopar ATF+4 Type 9602 Automatic Transmission

    AWD Power Transfer Unit - Multipurpose Gear Oil SAE 80W-90 meeting API
    specification GL-5.

    AWD Overrunning Clutch - Mopar ATF+4 Type 9602 Automatic Transmission

    AWD Rear Carrier - Multipurpose Gear Oil SAE 80W-90 meeting API
    specification GL-5.

    I'll check out synths for the AWD Power Transfer Unit, and rear
    carrier. Thanks again. Will leave tranny and Overrunning Clutch alone
    per the manual. Don't need TC probs or others!

    I believe ATF+4 is a synthetic fluid. Regardless, I wouldn't use anything else in a
    new Chrysler transmission. (Or an old one for that matter). LH differential units
    have a service warning not to use synthetic gear lubricant. I would be sure your AWD
    units do not have a similar warning in the service manual before using synthetic

    Factory manual says I can use synthetics in the crank case. (at normal
    drain intervals with filter) The section regarding the Trans,
    specifically mentions use other than "recommended fluid may cause
    deterioration in transmission shift quality and/or torque converter
    shudder". Oh well...thx

    Does anyone know why that warning is there? Bad reaction with ATF+3 or
    +4 if it leaks past the seal between the diff and the tranny? I've
    always been curious.

    The Pacifica drivetrain is standard Chrysler hardware, with the standard
    Chrysler recommendation: follow the factory recommendations in your owners
    manual. Anything else could destroy your transmission, at your expense not
