Ford Mustang (1999-2004) Service Manual: Transmission (REMOVAL)

Special Tool(s)

Retainer, Torque Converter 307-346 (T97T-7902-A)

CAUTION: Whenever a transmission has been disassembled to install new parts the transmission fluid cooler tubes must be cleaned and backflushed. Use a suitable torque converter/fluid cooler cleaner. If equipped a new oil-to-air cooler must also be installed.

These contaminants are a major cause of recurring transmission troubles and must be removed from the system before the transmission is put back into use.

CAUTION: After transmission is removed for a major overhaul, it is important to completely clean all transmission components, including torque converter, oil-to-air cooler if equipped, cooler inlet tube, main control valve body, clutches and all coasting booster valve shuttle balls after any transmission repair that generates contamination. These contaminants are a major cause for recurring transmission concerns and must be removed from the system before the transmission is returned to use.

The cleaning of foreign material from the direct clutch check ball is often omitted. This omission can lead to repeat repair of the transmission.

If equipped a new oil-to-air cooler must be installed under the following conditions; for installation refer to Section.

• Evidence of transmission assembly or fluid contamination is found due to the following transmission or converter failure modes:

• major metallic failure
• multiple clutches or clutch plate failures
• sufficient component wear which results in metallic contamination.

1. Place the transmission range selector lever in NEUTRAL.

2. Disconnect the battery ground cable. For additional information, refer to Section.

3. Raise and support the vehicle. For additional information, refer to Section.
