The same way you handle the engine oil project, you need to replace the transmission fluid in your Dodge Neon at regular intervals. Chrysler recommends changing the fluid every 24,000 miles or two years to assist flush out particles, like metal and friction material that accumulate in the oil over time and accelerate components wear. Replacing the oil at regular intervals will not only assist you keep repair costs down but equally increase the service life of your Neon transmission.
Draining the Transmission Fluid
Have your Dodge Neon driven for 20 minutes at highway speed then park the ride on a firm, level surface.
Shift your transmission into neutral, apply the parking brake and block the rear tires with two wheel chocks. Carry up the front of the Neon Dodge with a floor jack and then support it on two jack stands.
Put on a pair of goggles, go under your vehicle and place a large drain pan directly under the transmission pan.
Take off the mounting bolts from the sides and front of the transmission pan using a ratchet, long ratchet extension and socket. Ensure not to burn your hands as hot transmission fluid will start to drain from the pan. Loosen the pan rear bolts about four turns, hold the bottom of the pan with a shop rag with one hand and complete the removing of the rear pan bolts.
At this point, lower the transmission pan over the drain pan. Tilt the transmission pan to drain the remaining oil into the drain pan then remove it from the car. Carefully pull off the transmission filter from the bottom by hand and the O-ring seal from the filter mounting fitting.
Refill the Transmission Fluid
Scrape off any sealant material from the drain pan and the mating surface at the bottom of the transmission using a gasket scraper. When done, thoroughly clean the mating surfaces and mounting bolts with solvent and let the parts air-dry.
mount an new O-ring seal at the filter mounting fitting and a new transmission filter
Apply a continuous, 1/8-inch wide bead of silicone adhesive sealant around the transmission pan mating surface, circling around the outside of the mounting holes.
Put the transmission pan in position with one hand and fix the mounting bolts finger-tight with your other hand. Gradually start to tighten the mounting bolts with the ratchet, long ratchet extension and socket, beginning at the center of each side and working your way towards the front and rear of the pan. Torque the mounting bolts to 165 inch-pounds with a torque wrench, long ratchet extension and socket.
Lower your car off the safety stands with the jack.
Draw up the hood, pull out the transmission dipstick from its tube and refill the transmission with 4 quarts of ATF+4 Type 9602 through the dipstick with a funnel.
Start the engine. With the parking brake still applied, push the brake pedal to the floor and hold it at that position. Shift the transmission gradually through every gear then back to park. Allow the engine idle.
Reinsert the transmission dipstick then draw it out again. The fluid level on the dipstick should be about 1/8-inch below the lower mark close to the tip of the dipstick. Include very small amounts of fluid to get the fluid to the correct level, if required, then shut off the engine.
