Here we go----
1. Jack up and safely support vehicle.
2. Remove the transmission pan and filter. (this can be messy)
3. Remove little plastic plug on bottom of bell housing.(If it is still there after the years.)
4. Turn the engine over by havd until you see a small nut on the torque converter through the little hole.
5. Remove said little bolt.
6. Take a break, it takes a long time for 8 quarts of fluid to drain out of that little hole.
7. When fluid stops draining, replace little bolt.
8. Replace transmission filter and pan.
9. Remove BOTH transmission cooler lines from the passenger side of the transmission.
10. Use some transmission flush in an aerosol can to blow the old fluid from the cooler and lines.
11. When cleaner comes out (instead of transmission fluid) re-install the transmission cooler lines.
12. Make sure everything is assembled back and all bolts are tight.
13. Pour about 6 quarts of transmission fluid in the transmission.
14. Start car and run it through the gears without allowing the wheels to turn.
15. Shut vehicle off.
16. Add 4 more quarts of transmission fluid.
17. Start vehicle and run through the gears again without allowing wheels to turn.
18. Lower vehicle to the ground.
19. Start vehicle and allow it to come to operating temperature.
20. Check fluid and top off as needed to fill up to top of full mark.
21. Test drive vehicle
22. Re-check transmission fluid and look under vehicle for leaks.

Parts list.

1. 12 quarts of transmission fluid. (Mercon)
2. 1 transmission filter.
3. 2 cans of transmission flush.
4. Various clamps and hoses to connect cleaner to the transmission cooler lines.
5. Optional can of transmission shudder guard.

After thought---- If you have the parts house look up the lock up solenoid and show you one, you can readily find it. It is a small solenoid hooked to the valve body.


Good luck and hope you get it finished.
