Symptoms Of Bad 4l60e Shift Solenoids When assessing a shift solenoid issue, there can be a number of things to consider.
When the computer commands a downshift, fluid is routed through the solenoids, so if a solenoid is stuck, it is not able to effectively move transmission fluid which results in the transmission staying in the same gear.
Delayed or Inconsistent Shifts — If your shift solenoids are failing, you may quickly notice that the transmission will start to shift in a very inconsistent and delayed manner. Another thing that might happen is that the transmission will try to hunt or find the correct gear to be in. How To Test Shift Solenoid On A 4l60e One very easy way to test your shift solenoids is actually with a simple 9v battery to see if the solenoids are being activated.

The coil wire can go bad in a couple of ways and additionally, the plunger could also get stuck.
You can test shift solenoids using an OHM meter. If the solenoids have a resistance between 20 — 30 ohms, they are good. If the resistance is below 20 but still registers, the solenoid has probably melted. If there is no resistance, the solenoid is broken. For this reason, dealing with solenoids is not a recommended DIY project. Dealing with the problem will be a less stressful experience if you pay for the tow to a professional mechanic who can do the work quickly and correctly.
If the solenoid is broken, it will no longer be able to create the proper magnetic field needed for the vehicle to run properly. There is going to be a lot of harsh vibration when the solenoid is broken. If the solenoid is melted it will also display a harsh vibration but additionally will cause extreme temperatures within the transmission.
If the plunger is stuck, it is almost always caused by dirty transmission fluid or some type of debris. Luckily the plunger can be easily replaced and when that service is done, it would be wise to replace the transmission fluid and filter too, that way the dirty fluid is removed.
