ISSUED: 07/88-1063
SUBJECT: TRANSMISSION DAMAGE DUE TO COOLANT CONTAMINATION IN THE AUTOMATIC TRANSMISSION FLUID.

APPLICATION: 9000 MODELS WITH ZF AUTOMATIC TRANMISSION
Replacing a transmission that is damaged due to antifreeze contamination requires extra care to prevent contamination of the replacement unit. (See SI 07/88-1062 about checking for radiator/transmission oil cooler leakage and the symptoms which indicate transmission damage).

Cooling circuit flow for 9000 ZF automatic transmission.:

Action Required:

1. Replace the engine radiator whenever ATF inspection indicates antifreeze contamination.

2. Remove the air-cooled oil cooler, thermostat, and oil cooler hoses and clean thoroughly to remove any traces of anti-freeze. The SAAB Flushing Kit will not remove liquid contaminants.

3. Install replacement transmission and fill with new Dexron II ATF.

4. Clean and flush the transmission cooling system to remove any possible solid contaminants by using the SAAB Flushing Kit and a new filter (see SI 05/88-1057).

5. Flush engine cooling system to remove any traces of ATF. Refill with new SAAB antifreeze coolant (50/50 mix with water).

6. Check transmission line pressure settings using the pressure gauge and the upper test plug to ensure that they are within specification as per Service Manual 4:2. Adjust throttle cable as needed.
