4l60e transmission pump failure symptoms

Shift flares and harsh downshifts. Many Saab vehicles use a 5-speed automatic transmission designated as Aisin AW55, which can develop into a very common issue. Drivers experience symptoms like shift flares that occasionally happen on accelerations or harsh downshifts. This affects shifts between the 2nd and 3rd gear.

When your 4l60e’s TCC solenoid begins to fail, there are a number of obvious signs. The main symptom of a TCC solenoid failure is the converter is not locking up. When the converter is not locking up you will notice the engine’s RPMs staying higher under load at highway speeds. Another symptom of a failed TCC solenoid is a fault code.Worst case: poor line pressure rise (see below). 3. 1-2 Shift shudder at WOT; delayed or abnormal 1-2 shift; There's a problem ONLY on the 1-2 shift: 1-2 accumulator piston cracked or stuck cocked in the bore.

Pulsating Acceleration Detected. If your transmission pump fails, it can increase the number of pulses in the engine RPM while accelerating. The throttle action will be sluggish and slow because it's not obtaining enough power from the torque converter, so you won't accelerate as fast as you normally can. 2.What causes 2/3 shift flare 4L60E? Some of the most common causes of 2-3 flare or shifting issues with a 4L60-E transmission are related to problems inside the transmission itself. Low line pressure caused by clogged filter, worn pump, etc. is one of the main culprits behind this issue and can be easily identified and remedied.There are 2 shift solenoids in a 4l60e (1-2 and 2-3), and both control up and downshifts with fluid passing through them when commanded to do so by the computer. However, when they go bad, you will notice very quickly. Your transmission will display a variety of symptoms, but sometimes these issues can be confused by other common 4l60e issues.Worst case: poor line pressure rise (see below). 3. 1-2 Shift shudder at WOT; delayed or abnormal 1-2 shift; There's a problem ONLY on the 1-2 shift: 1-2 accumulator piston cracked or stuck cocked in the bore. Check the yellow spring inside the accum housing for breakage.Body of Evidence. It is not too often that you see a no-reverse concern caused by a bad solenoid or by a valve-body problem that does not affect any forward upshifts. Generally you’ll see this only on valve bodies that have a reverse-inhibit function, such as the 5L40 or JF506.
