In this article, we go over some of the most common problems that affect Saab vehicles with automatic transmission.
Saab 9-7 vehicles have a 4L60E 4-speed automatic transmission, which can suffer from problems when shifting to higher gears.
In some cases, the transmission will only shift to 2nd gear, while 3th and 4th gear will not be available. Even more severe problem is when the transmission stays stuck in 1st only, losing the ability to engage other forward gears and reverse. The problem can be intermittent or constant and usually does not trigger any warning lights.
Possible causes and solutions:
First-generation Saabs 9-5 that use a 50-40/42LE 4-speed automatic transmission can experience loss of reverse after the transmission has been removed and refitted to the vehicle. In most cases, it will not engage reverse gear when selected from neutral but works if the gear lever is quickly moved from drive to reverse.
Possible causes and solutions
Saab 9-7 vehicles have a 4L60E 4-speed automatic transmission that can suffer from intermittent gear shift issues.
In most cases, this will show as delayed or failed gear upshifts while accelerating. Sometimes, the transmission will fail to downshift during accelerations or when slowing down. These issues usually trigger the check engine light; there will be a corresponding error code stored in the vehicle's DTC memory.
Possible causes and solutions:
Many Saab vehicles use a 5-speed automatic transmission designated as Aisin AW55, which can develop a very common issue.
Drivers will experience symptoms like shift flares that occasionally happen on accelerations or harsh downshifts. This affects shifts between 2nd and 3rd gear. In the initial stages, this issue will be more noticeable while the car is cold but gets more severe with time.
Other symptoms include an illuminated check engine light, meaning there will be a trouble code stored in the DTC memory.
Possible causes and solutions:
Later, Saabs 9-3, with a 6-speed automatic transmission designated as AWTF-80, can develop an issue that will manifest itself as a prominent shift flare. In most cases, this will only happen on mild accelerations, while more aggressive ones will go without this problem. In some cases, there will be a noticeable delay when coming to a stop. Usually, there will be no other symptoms.
Possible causes and solutions
These are some common Saab transmission problems. Note that just because you own a Saab, it does not meet that you will experience any of these problems.
If you are experiencing a problem with your Saab transmission, call the dealer or use a VIN decoder to find out which transmission is installed in your car. Then research the problems that affect that particular transmission.
