Does a 2002 caravan need transmission cooler or is the one behind main rad tranny cooler?

A 2002 Dodge Caravan likely has a transmission cooler integrated into the radiator. However, it's not guaranteed. While many vehicles of that era used this design, some might have had a separate, standalone transmission cooler added, or it may have been factory-installed as an option depending on the trim level or towing package.

To be certain, you need to:

* Check your owner's manual: This is the best place to start. It will specify the cooling system used for your specific model.

* Inspect the radiator: Carefully examine the radiator for transmission fluid lines connected to it. If you see lines going into and out of the radiator, that's a good indication of an integrated cooler.

* Look for a separate transmission cooler: Check in front of the radiator for a small, separate cooler. It will usually be a smaller radiator-like unit with fluid lines connected.

Without physically checking your vehicle, it's impossible to say definitively whether it has a separate cooler or just the one integrated into the radiator.
