how do i check the transmission fluid on 2007 pacifica

If there is no dip stick to check the fluid, then there would be a plug on the side of the trany somewhere to pull, and if fluid runs out to level being 1/2 inch below the threads, then it is full.

Didn't know about a plug but will check. Also should the fluid be hot or cold ?

i cant find the dip stick

You will have to order a special cable style dipstick put it in there in the plug and also take the temperature of the tranny fluid and then go to the accompanying chart that comes with that special dipstick and then you will know roughly where you should be with your fluids good luck I found my kit on Amazon for I remember correctly.

Where is the plug
