For 1990-2009 cars

1. Slowly rotate the transmission to a vertical position to drain the transmission fluid out of the extension housing.
2. Remove the transmission case oil pan bolts (173).
3. Remove the transmission case oil pan (172).
4. Remove the transmission case oil pan gasket (170).
5. Remove the oil pan magnet (171).

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. If the vehicle is equipped with four-wheel drive, place reference marks (1) on the propeller shaft pinion flange and the front differential pinion flange (3) of the transfer case to the front differential propeller shaft. Refer to Propeller Shaft Replacement in Propeller Shaft.
3. Remove the following components in order to separate the pinion flange yoke (2) from the front differential pinion flange (3) (four-wheel drive models):

3.1. | The 4 pinion flange bolts

3.2. | The 4 pinion flange nuts

4. Position and support the transfer case to the front differential propeller shaft away from the transmission fluid pan.

Important: Removing the propeller shaft from the transfer case will cause fluid loss with four-wheel drive models.

Notice: This transmission is not equipped with a fluid pan drain plug. Be sure to place a drain pan, or other suitable container, under the transmission fluid pan before loosening the fluid pan seal. Transmission fluid will begin to drain out immediately after the fluid pan seal is loosened.

5. Place the drain pan (3) or a suitable container under the transmission fluid pan (2).
6. Remove the 9 transmission fluid pan bolts around the forward perimeter of the transmission fluid pan (2).
7. Loosen the 3 transmission fluid pan bolts in the rear of the transmission fluid pan (2), allowing the transmission fluid pan to partially drain.
8. Remove the 3 remaining transmission fluid pan bolts.
9. Remove the transmission fluid pan (2).
10. Remove the transmission fluid pan gasket.
11. Drain the remaining fluid from the transmission fluid pan (2) into the drain pan (3).
12. Remove the three fluid filter screen bolts (2) from the valve body.
13. Remove the fluid filter screen (1) and the fluid filter screen gasket.

Important: A small amount of clutch material in the bottom of the transmission fluid pan (1) is a normal condition and is consistent with normal transmission wear. The bottom of the transmission pan (1) is equipped with a magnet (2) that will collect minute metal filings. However, transmission disassembly and inspection are indicated if large amounts of clutch material, metal shavings or other foreign matter are present.

14. Clean the following components:

• | The fluid filter screen

• | Use solvent in order to clean the fluid filter screen and air dry.

• | The transmission fluid pan (1)

• | The transmission fluid pan magnet (2)

• | The fluid filter screen gasket mating surfaces

15. Inspect the fluid filter screen for any tears or other damage.

Replace the fluid filter screen if necessary.
