    Its lifetime fluid, so just add it to your will so whoever inherits your truck can worry about changing it when your dead.

    The basic design of trans has been around a while. It's proven reliably so far.

    I'm just interested in seeing when trans tuning comes available, how many start to blow them.

    How can it be lifetime? Sounds sketchy.

    Just drain and add

    All you need to do is drain the fluid and add what you took out via a pump through the side fluid check hole. I will do this at 50k and every 25k miles after that.

    Will consider a filter change as well but by then there will some aftermarket options.

    The can say lifetime but I'll err on the side of caution.

    There are two plugs on the transmission. A drain plug, the one you see in the plastic pan, and a fill plug. The fill plug may be on the side or on the tail end of the transmission.

    This is from ZF's documentation. The procedure from Chrysler is likely the same:

    Transmissions fluid level checking.

    1) The transmission fluid temperature must be between 30°C and 35°C before checking can begin. Use test equipment to determine the trans temperature.

    2) The vehicle must be level with engine running at idle speed and air conditioning turned on.

    3) Step on the brakes firmly, apply parking brake fully and shift to D and R, briefly pausing in each position before shifting back to the Park position.

    4) With the engine running at idle speed and the selector in Park position, remove the filler plug. Monitor the transmission temperature, if a small stream of oil runs out at 40°C, the fluid level is correct.

    5) If no oil runs out when the filler plug is removed, the fluid level is too low and oil needs to be added until it overflows.

    6) With engine running, install the oil filler plug and tighten to proper torque.

    The reason for buying the 2015, Hemi was for the German 8PH70, ZF transmission as opposed to the Chrysler manufactured 845RE , 8 speed , licenced from ZF mated to the V6 Penastar.
    Actually preferred the Penatar V6 with 3.55:1 differential to the hemi , but bought the hemi\8PH70 ZF truck for the transmission.
    Some research showed the 845RE transmission valve body was totally replaced for 2015 model year, but even some of the early 2015 Penastar\845RE had the previous 845RE valve body. The is no way of knowing what valve body was assembled with the 845RE transmission, even by Vin #.
    The 2012-2014, 845RE transmission had many issues. It would cost $1800 to replace the updated valve body,
    which was the adder to go with German 8PH70 ZF 8 speed.

    There is a commercial grade video posted on U- tube showing the8PH70 ZF operation.
    The transmission goes not have any conventional fiber material clutch plates.
    Therefore, the ZF transmission fluid is not contaminated with clutch material particles, requiring conventional fluid changes.
    However, the transmission is only 100k warranty. Now have 200 k on 4 cylinder Honda transmission, but changed fluid on 60k OCI.

    Agree, transmission level should be checked based on previous post.

    I will just trade mine at a100k , just like I've done with the last 4. Problem solved. That looks like a pain in the ass to get that right.

    Sure, it's not as easy as the old dipstick. A little more time consuming, but it's
    not tough. After servicing, add fluid until it just starts to dribble out. Start the truck engine. Add more fluid until a little bit dribbles out. Put the fill plug in. Take the truck out and drive it around until the trans is at operating temp. Park on level ground, remove the fill plug and check/adjust as necessary.
