Pacifica Transmission flush
I was going to bring my 2020 Pacifica to a Dealer to have the transmission fluid changed. They said that they would flush it. Is that safe?
Only do a drain and refill; don't do a flush.
Also, for anything other than warranty or recall work avoid dealerships; find a trusted independent mechanic.
See below: That vehicle uses the ZF 9-speed (948TE) also used in the Chrysler 200 (video within link below is for 200 but also applies to the Pacifica; do drain and fill only (change/service filter if applicable); also you want to add the same amount of fluid that is drained out)
Those transmissions were weak so I would actually drain and fill (service filter if applicable) no more than every 30,000 miles. And baby that transmission to get more life out of it.
