Can a bad Shift Solenoid cause a transmission to slip?
TIP 3: A bad transmission shift solenoid A or B will not cause the transmission to slip. So if your transmission is slipping, replacing the shift solenoids, even if they’re fried will not solve the slipping issue. The 4L60-E transmissions uses several solenoids and sensors to control/activate its 4 gears.
What’s the difference between shift solenoids A and B?
The Shift Solenoid Connector’s Locking Tab Broke. Before You Remove The Transmission Oil Pan. The Sediment At The Bottom Of Transmission Pan. You can find this tutorial in Spanish here: Cómo Probar Los Solenoides De Cambio A y B (1999-2010 V8 Chevrolet Silverado, GMC Sierra) (at: autotecnico-online.com ).
What are the symptoms of a bad 4L60E Shift Solenoid?
This action makes the transmission shift into different gears. This movement is achieved through the creation of a magnetic field within them. Here are the main symptoms of a bad 4L60E shift solenoid. Failure to Downshift – The 4L60E will often fail to downshift if one or more of the shift solenoids are stuck open or closed.
How can I tell if my transmission solenoid is bad?
To read the trouble codes from the transmission control module, you need an OBD2 scanner to read generic and enhanced trouble codes. Most cheaper ones can only read the codes from the engine control module. If the transmission control unit recognizes any shift solenoid problems, it may cause the transmission to shift very slowly.
Can a slipping transmission be a solenoid problem?
Do not confuse a slipping transmission with a solenoid problem. You will hear and feel the difference when you try to shift. A slipping transmission will actually shift, but then not produce any power once in gear, whereas a bad solenoid will prevent the shift from occurring in the first place.
Where is the shift solenoid on an automatic transmission?
When it’s time to shift, the transmission control unit sends out power or ground to the required shift solenoid, and it causes the solenoid to open and let the transmission oil flow into the valve body, which then shifts to the next gear. The Transmission shift solenoids are located inside the valve body of your automatic transmission.
What happens when Shift Solenoid goes bad in 4L60E?
Inconsistent Shifting– Often when a shift solenoid goes bad in the 4L60E, it’ll cause a lot of erratic shift behavior. The transmission will skip gears. It also may act like it is trying to “find the right gear”.
What happens if you have a bad solenoid?
If one or more solenoids are bad, you may lose the use of one or more gears, and may even be stuck in one particular gear or unable to shift into any gear at all. Do not confuse a slipping transmission with a solenoid problem.
