Here's a general overview, but remember this is not a substitute for your owner's manual:
If your Caravan has a dipstick:
1. Find the dipstick: It's usually located near the transmission, often with a bright colored handle (red, yellow, or orange are common). It might be marked "ATF" (Automatic Transmission Fluid).
2. Check the fluid level: With the engine running and warmed up (to operating temperature), remove the dipstick, wipe it clean, reinsert it fully, and remove it again. The fluid level should be within the marked "full" range on the dipstick.
3. Add fluid: If the level is low, carefully add the correct type of transmission fluid (consult your owner's manual for the specified type). Use a funnel to avoid spills. Add small amounts and recheck the level frequently. Never overfill.
4. Run the engine: After adding fluid, run the engine for a few minutes to circulate the fluid. Re-check the level.
If your Caravan does *not* have a dipstick (this is more common in later model years, but possible on some 2002s):
This is significantly more complex and requires more specialized knowledge. Do not attempt this yourself without proper training and tools. You'll likely need to locate the fill port (often requires removing a cover or component), which is different from the drain plug. You'll also need a special tool to measure the fluid level accurately, typically using a transmission fluid level gauge. Taking it to a qualified mechanic is strongly recommended.
Important Considerations:
* Fluid Type: Using the wrong type of transmission fluid can severely damage your transmission. Your owner's manual will specify the correct type (e.g., Dexron III, Mercon, etc.).
* Overfilling: Overfilling the transmission is just as bad as underfilling. It can cause damage and leaks.
* Leaks: If you notice transmission fluid leaks, address them immediately.
* Professional Help: If you're unsure about anything, or if you encounter difficulties, take your Caravan to a qualified mechanic. The cost of a repair due to improper fluid addition or a missed leak will likely far outweigh the cost of professional service.
In short: Get your owner's manual. It is your most important resource for this procedure. Failing to consult it could lead to costly transmission damage.
