Hi

For a while now our van (2000 Dodge Caravan v6 3.0) has been leaking fluid from the bottom of the engine and on to the driveway. The bottom of the engine is covered in a wet substance. I am thinking it's transaxle fluid, but not sure. What can it be?

Here's the pictures:

 

Additional symptoms, while turning the steering wheel, you hear a creaking sound (related to turning the steering wheel); like floorboards.

 

It looks like your transmission solenoid pack is leaking transmission fluid. if that's the case, you have to replace it because if you try to open it up and replace the leaking seal/gasket, you will mess up the internals. Same thing happened to mine at around 98K, I bought one brand new from Ebay for about $90.00 and installed in in less than half an hour. In your 13th and 14th photo, it's the component visible in the top left corner of the photo, small black box attached to front facing side of the trans. Wipe that area real clean with a rag then drive a little bit and check back underneath and see if you can see a clean trickle of fluid coming from the solenoid pack.

 

The solenoid pack is leaking, also looks like the cooler lines at the radiator are leaking. And ck the rear cam plugs too.
