Here's how to perform a partial transmission fluid change:
Tools and Materials:
* New ATF (Automatic Transmission Fluid): Consult your owner's manual for the correct type and amount. Dexron III is a common choice for this year and model, but double-check.
* Transmission fluid drain pan: Large enough to hold several quarts of fluid.
* Wrench: The size needed to remove the transmission pan drain plug. (Likely a 10mm or 13mm socket)
* Socket wrench set: to access transmission pan bolts.
* New transmission pan gasket: Essential to prevent leaks.
* Funnel: For adding new fluid.
* Jack and jack stands: For safe vehicle access.
* Wheel chocks: For added safety.
* Gloves: To protect your hands.
* Rags or shop towels: For cleaning up spills.
* Torque wrench (recommended): To tighten the transmission pan bolts to the correct specification. This prevents leaks and damage.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake firmly, and use wheel chocks. Jack up the vehicle and securely support it on jack stands. Never work under a vehicle supported only by a jack.
2. Locate the Transmission Pan: The transmission pan is located on the bottom of the transmission. It's usually a fairly large metal pan.
3. Warm Up the Transmission: Run the engine for 5-10 minutes to warm the transmission fluid. This helps it flow more easily.
4. Drain the Fluid: Carefully position your drain pan under the transmission pan. Locate and remove the drain plug. Let the fluid drain completely. Note the amount of fluid that drains out; this gives you a rough estimate of how much to refill.
5. Remove the Transmission Pan: Once drained, remove the transmission pan bolts. Be careful as some fluid may still remain in the pan. Have your drain pan ready to catch any remaining fluid. Note the location of the pan and gasket.
6. Inspect the Pan and Filter (If Applicable): Inspect the pan for any debris or signs of damage. Some models have a replaceable filter attached to the pan; replace if necessary. If the pan is very dirty or magnetized with metal shavings, cleaning or replacing it might be advisable, but is not strictly required for a partial change.
7. Install New Gasket and Pan: Carefully clean the pan mating surface on the transmission. Install the new transmission pan gasket, ensuring it's properly seated. Replace the transmission pan and tighten the bolts evenly and to the manufacturer's specified torque (consult a repair manual). Don't overtighten!
8. Refill the Transmission: Using a funnel, carefully add the recommended amount of new ATF. Refer to your owner's manual for the correct amount. It's usually close to the amount you drained.
9. Check the Fluid Level: This is crucial. With the engine running and the transmission in park, check the fluid level using the transmission dipstick. The dipstick might be difficult to reach; you might need a flexible dipstick extension to get to it. Add more fluid as needed until it reaches the "full" mark.
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Test Drive: Take the vehicle for a short test drive to circulate the new fluid.
12. Re-Check the Fluid Level: After the test drive, re-check the transmission fluid level again while the engine is running. Add more fluid if necessary.
Important Considerations:
* This is a partial fluid change: Only a portion of the transmission fluid is replaced. To get a more complete exchange, you would need to repeat this process several times over a few weeks, draining and refilling each time.
* Consult a Repair Manual: A repair manual specific to your 1994 Dodge Spirit 2.5L will provide detailed diagrams and torque specifications. This is highly recommended.
* Professional Service: If you're uncomfortable performing this task yourself, it's best to take your vehicle to a qualified mechanic for a professional transmission fluid service. They can perform a complete fluid exchange and diagnose any potential problems.
This procedure is a general guideline. Always consult your owner's manual and a repair manual for your specific vehicle before attempting any repairs. Improper transmission fluid maintenance can lead to serious transmission damage.
