Transmission fluid on 07 chry pacifica

It is a non serviceable trans and cannot be checked at home. It must be taken to a dealership, the dipstick is a dealer only special tool and they use a trans computer scan tool to read temp,ect. You don't check it. it is a sealed case transmission under the hood where the dipstick should be is a cap that says dealer use only the computer will tell you how many miles remain before recommended service is due. I have heard that if doing the filter change to collect the fluid and measure it and add threw the dealer service only cap the same amount which should be between 4 & 5 quarts if there were no leaks and if there is leaks then without the service dipstick from dealer there is not way to tell how much to add back in and the type of fluid I do not know that answer.

If you find the same motor that has a dipstick you can use that dipstick to replace the cap. Also as far as transmission fluid it doesn't really matter although I feel Lucas oils are better

@Engine Creator, you're saying though the cap says (Dealer only) on the 07 Pacifica, we could still at transmission fluid?

The issue is over-filling the trans is bad and will cause it too burn up early, so I t needs to be drained and measured if not leaking to know how much to add back in. Unless you can purchase a dealer only tool Called the dipstick for the rest of us but I am sure the dealer is calling by a part number or some other unidentifiable name. I will see if I can come up with any other information on this.

which engine do you have the 3.8l or 4.0l V-6?

If yours is the 4.0l v-6 rockauto.com sell a dipstick (others may too) for the automatic transmission, which is a tool only and does not stay in the trans all the time (its a tool and removed after using it to find the correct fluid level). It is a DORMAN 917327 {#8863B, 9336} w/o tube, Maintenance tool, Does not remain in vehicle.

@Engine Creator: It's 3.8, but here's the issue I'm having. We had a horrible rain fall, before I knew it I was in water maybe to middle of tire rim and created a big splash. Drove done after, but next day wouldn't go over 30ml and does this periodically.

I did not see a dipstick tool for the 3.8L. I would say to pull all electrical connections and spray with electrical board cleaner (contact cleaner) to dry out all moisture and use dielectric grease (bulb grease) in those connections to keep moisture out. As far as the transmission goes if it is filled with water tow it too a dealership and have it changed out. I do not have a cure for this as the dealership is the only place that I know of that for sure has the tool needed to check the level for you and also replace the fluid with new and get it too the correct level, The connections there for the sensors or solenoids may just need the moisture removed, Unless you know it is water filled in the transmission case.

Transmission relay. Big block connected to radiator with large wire harness connected to it. It got wet

That big wire plug was all dirty and corrosion galore on my 07 Pacifica. Cleaned it up and all good now

Pretty good of answers if I must say so my self...yes , you can do it all from changing trany oil to water pump and timing belt on this Pacific's.....I bought one and been haven trouble after trouble with it but just wont give up on it....you can get the dipstick at any auto parts store, dont get scurd when u see it for it's a good 3 or 4 foot long . Now the bad thing about it is that it wont be sold to you with the chat needed to tell you how much oil it is going to need but can be down loaded over ther net. I too been haven prob with it not shifting out of first gear not even if I put it on autostick that when I do , the auto shift wont engage.

This place is full of crap.right side by fender so to speak is a little back cap half way down.get a universal dip stick it should read 37 to 42 on it for proper filling.go to Oriellys.auto. ask for fluied type and dip stick to bowrrow.they do it for you.proble under 20$.good luck ladys

Between 37 and 42 is a safe range I have a 2007 Chrysler Pacifica
