Saab 2007 owner manual Overheated transmission fluid, Gearbox too hot. Make a safe stop

154 Starting and driving

Automatic transmission 3, fault indicator

If ”Automatic transmission 3, fault indicator” lightappears on the main instrument panel, the system has detected a fault in the auto- matic transmission or its control module (see page 62).

This also means that the Limp-home mode has been selected, to guard against further damage being done to the transmission. In this mode, the automatic transmission starts in 5th gear, and gear changes (if nec- essary) will have to be made manually.

Stop the car in a safe place. Switch off then restart the engine. If the fault is intermittent, the transmission will operate as normal despite the fault indicator being on. Have the car checked at a workshop. We recom- mend that you contact an authorized Saab dealer.

It is not possible to select the SPORT or Sentronic mode when the Limp-home mode is active.

Gear changes must be made manually.

The following gears will be engaged in the respective selector positions when the auto- matic transmission is in Limp-home mode:

Position	R	D	M	L
Gear	Reverse	5th	5th	2nd

NOTICE

If the control module has actuated the Limp-home function for the automatic transmission, the car will remain in 5th gear when D is selected, making it very sluggish.

Select position L to prevent unnecessary wear on the transmission. The transmis- sion then starts in 2nd gear. Once the car is moving you can select position D.

When the indicator light is on, the car must not be driven with a caravan or trailer attached.

Overheated transmission fluid

If the automatic-transmission fluid should overheat, the following message will appear on the SID:

”Gearbox too hot. Make a safe stop.”

In this event, stop the car in a suitable place, switch off the engine and open the hood.

Wait for several minutes then turn on the ignition to check that the message has gone out. When driving subsequent to the trans- mission fluid overheating, select a gear in which the engine speed is about 3,000 rpm.

Overheating of the automatic-transmission fluid can occur when the car is towing a heavy load, such as a camping trailer in hilly country. High ambient temperatures can also increase the temperature of the trans- mission fluid or the oil cooler may be faulty. Contact a workshop. We recommend that you contact an authorized Saab dealer (see also page 174).
