GENERAL PROCEDURES
Transmission Fluid Cooler —
Backflushing and Cleaning
1. CAUTION: Do not use any supplemental transmission fluid additives or cleaning
agents. The use of these products could cause internal transmission components to fail;
this will effect the operation of the transmission.
Conduct backflushing with a suitable torque converter/fluid cooler cleaner. Test your equipment
to make sure that a vigorous fluid flow is present before proceeding. Install a new filter in the
flush equipment if flow is weak or contaminated.
2. To aid in attaching the cleaner to the transmission steel cooler lines, connect two additional rubber hoses to the transmission end of the steel transmission cooler lines as described below.
zConnect the cleaner tank pressure line to the steel transmission cooler return line
(longest line).
z Connect a tank return hose to the steel transmission cooler pressure line (shorter line).
Place the outlet end of this hose in the solvent tank reservoir.
3. Turn on solvent pump and allow the solvent to circulate a minimum of 5 minutes (cycling switch on and off will help dislodge contaminants in cooler system).
4. Switch off the solvent pump and disconnect the solvent pressure hose from the transmission cooler return line.
5. Use compressed air to blow out the cooler(s) and lines (blow air into the transmission cooler return line) until all solvent is removed.
6. Remove the rubber return hose from the remaining steel cooler line.

GENERAL PROCEDURES
Transmission Fluid Drain and Refill
Draining
CAUTION: Always refer to the instructions supplied with the flush and fill machine.
NOTE: Draining fluid from the transmission by removing only the fluid pan is acceptable for vehicles
that do not have a torque converter drain plug, for normal or severe duty fluid maintenance.
NOTE: A new procedure for draining and adding transmission fluid using a suitable transmission flush
and fill machine has been added. The following procedure has different methods for draining and
refilling the listed vehicles:
zAll vehicles using a suitable flush and fill machine.
z Vehicles equipped with a torque converter drain plug.
z Vehicles without a torque converter drain plug.
Use the method that is applicable to your vehicle.
All vehicles using a suitable flush and fill machine 1. With the vehicle in NEUTRAL, position on a hoist. For additional information, refer to Section 100 - 02 .
2. Use a suitable flush and fill machine to change the fluid.
3. When connecting the flush and fill machine, connect the machine to the fluid cooler tube after the fluid cooler on the cooler return line. This will help remove any foreign material trapped in
the fluid coolers. Refill SECTION 307-

4. Use only clean automatic transmission fluid.
5. Once the fluid exchange has been completed, disconnect the flush and fill machine. Reconnect
any disconnected fluid cooler tubes.
6. With the engine running and the transmission at normal operating temperature 66- 77°C (150-
170°F), check and adjust the transmission fluid level, and check for any leaks. If fluid is needed,
add fluid in increments of 0.24- liter (0.5-pint) until the correct level is achieved (fluid should be in
the cross- hatched area of the fluid level indicator).
Draining
Vehicles equipped with a torque converter drain plug 1. With the vehicle in NEUTRAL, position on a hoist. For additional information, refer to Section 100 - 02 .
2. Loosen the transmission fluid pan bolts and allow the fluid to drain.
3. After the fluid has drained, remove the transmission fluid pan.
4. Do not remove the fluid filter. It is not necessary to change the fluid filter during a normal maintenance fluid change.
5. Remove the torque converter drain plug cover. Klj . 2 ba

10. Install the torque converter drain plug cover.
11. Position the magnet into the transmission fluid pan.
12.
NOTE: The fluid pan gasket is reusable, clean and inspect for damage. If not damaged, the
gasket should be reused.
Install the fluid pan and gasket. 1. Position the fluid pan with the gasket in place.
2. Install the bolts.
13. CAUTION: The use of any other transmission fluid can result in the transmission
failing to operate in a normal manner or transmission failure.
Fill the transmission.
zAdd 4.7 liters (5 qts) of clean automatic transmission fluid to the transmission through the
fluid filler tube.
14. Start the engine. Move the transmission range selector lever through all the gear ranges, checking for engagements.
