Saab 9-5 - Automatic Transmission Fluid (ATF) change - 2.3t and 2.3T
These instructions are for the 2.3 4-cylinder engine.
Tools needed
- funnel
- 24mm wrench/spanner or adjustable wrench
- ramps or jack/axle stands for raising the front of the car
- container for draining the used ATF
Parts/supplies needed
Tip
4 quarts of ATF brings the fluid level right at the minimum on the ATF dipstick. 1 quart = 946ml so 4 quarts is 3.78 liters. Difference between min and max = 0.5 liters. I saved about 1/4 of the bottle of the 2nd change (used some of the drained ATF) and used that on the final change with the other 4 quarts so the level was right between min and max.
Important note
Starting with model year 2006, the engine does not have an ATF dipstick anymore . This may make it more difficult to fill and check the correct level. Please refer to the WIS instructions in this thread and check out this post before you drain the ATF: http://saabworld.net/showthread.php?...ll=1#post67224

Note: Saab changed the change interval through the years. While they advice 100K miles for MY03, it's safe to assume 60,000 miles should be used for all model years MY02 and up.
Difficulty rating (scale of 1 to 5):1 - Easy
This is very easy to do yourself. If you can hold a wrench, loosen/fasten a bolt and pour liquid from a bottle, you can do this!
Time estimate:1-2 hours for all 3 changes
Instructions
Warm up the engine and transmission by going for a short drive if the engine is cold.
Raise the car with ramps or use a jack and support the car with axle stands. I am sure this has been said many times before but never, never work under a car only supported by a jack. Not even for a few minutes. Never!

The drain bolt is located to the right of the exhaust when looking from the front of the car. It's the only 24mm bolt in that area so you can't mistake it for anything else. There is not enough room for a socket so an open-ended or ring wrench/spanner is needed. An adjustable wrench will be fine as well.

Place a container under the transmission and loosen the bolt. The ATF will start draining out slowly when the bolt is almost at its end. Removing the bolt will make the fluid gush out because it's a pretty large opening. Because the engine is warm/hot, this fluid can be very hot so be very careful not to get it all over your hands or arms. It really can cause severe burns.

Put the bolt back on. Use the old washer for now. Use the new washer after the final drain. About 4 quarts/liters is drained every time so fill up the transmission with 4 quarts/liters of new ATF. The fluid is added through the dipstick tube.
Attachment 1426
Warm up the engine. Shift through Drive and Neutral so the fluid can get distributed through the transmission. Check the fluid level and add if necessary. Drive the car for a while so the new fluid can mix with the old. Some drive it for a week between changes and others drive a few miles. At least 20 miles/30 kilometers seems a good choice but it's just a guess, really.
Repeat the process. The idea is to do at least three times because you can never get all the fluid out. There is about 3 liters left in the oil cooler and torque converter after all fluid is drained. Total capacity is 7 liters, according to the WIS.
After the first change, there is 4 liters of new fluid and 3 liters old fluid in the transmission so about 57% new. The second change drains another 1.5 liter (79% new fluid) of the old fluid and the third .75 liter. So after 3 changes, there will still be .75 liter of the old fluid left which is about 11%. But 89% of new ATF seems good enough for most. You can change the fluid an infinite number of times and you'll never get all the old fluid out. ;)
New fluid
1st change: 57%
2nd change: 79%
3rd change: 89%

How to check the ATF level
Automatic transmission, transmission fluid level with dipstick
1. Park the car on level ground and apply the handbrake.
2. Start the engine and allow it to idle. Select position D and wait for at least 15 seconds. Then select R and wait for 15 seconds. Repeat for position P.
3. Connect the diagnostic tool and run the engine until it reaches 80°C as per the "Read values" menu for TCM.
Attachment 1673
4. Check the fluid level (engine idling and selector lever in position P). Top up as necessary. Pay attention to the appearance of the fluid and its odour. If it is turbid or discoloured and/or smells burnt, a change of fluid is advisable even if no complaints have been made about poor shifting performance or excessive noise. Refer to Changing the automatic transmission fluid.
Important
In order to correctly read the oil level, the O-ring must be removed from the dipstick and refitted after reading.
Important
Fill up with oil through the dipstick pipe. Do not remove any plugs from the top of the gearbox.
Important
The dipstick has only one measuring range for warm oil. The oil volume between min-max is 0.5 litres (0.5 qts).
Automatic transmission, transmission fluid level without dipstick
1. Park the car on level ground and apply the handbrake.
2. Start the engine and allow it to idle. Select position D and wait for at least 15 seconds. Then select R and wait for 15 seconds. Repeat for position P.
3. Connect the diagnostic tool and run the engine until it reaches 80°C as per the "Read values" menu for TCM.
Warning
Risk for burn injuries when working on the catalytic converter.
4. Remove the plug using 30 16 516 Torx sleeve. Use butyl tape or the like to secure the plug on the tool.
Attachment 1674
5. Check the fluid level using DT-47653 Gauge rod. (engine idling and selector lever in P). Fill with fluid as necessary using 87 92 822 Oil filling equipment. Pay attention to the appearance and odour of the fluid. If the fluid is cloudy/discoloured and/or smells burnt it must be changed even if there is no noticeable reduction in shift quality or noise. See Changing the automatic transmission fluid.
