4l60e shift solenoid b – The issue
4l60e shift solenoid b problem, the shift solenoids are one of the most common culprits when your 4l60e begins acting up and not shifting correctly. A 4l60e has two shift solenoids (1-2 and 2-3), which regulate up and downshifts with fluid moving through them when the computer commands it.
When they go bad, though, you’ll notice right away. Your transmission will show a number of symptoms, however these problems can sometimes be mistaken with other typical 4l60e problems.
Fortunately, checking and replacing 4l60e shift solenoids (if necessary) is rather simple. Furthermore, if you discover that the shift solenoids are the source of your problems, they are affordable to acquire and fix yourself provided you have the necessary skills and knowledge.
Solenoids With A Bad 4l60e Shift Symptoms
There are several factors to consider while evaluating a shift solenoid problem. While 4l60e shift solenoids do fail occasionally, it is not frequent. A malfunctioning accumulator or a jammed shift valve, to mention a few, are common difficulties that may lead you to assume the 1-2 or 2-3 shift solenoids are failing. Testing your shift solenoids is the best approach to ensure that they are the source of the problem.
The following are examples of common shift solenoid failures or signs of a faulty shift solenoid:
• Failure to Downshift
If a shift solenoid isn’t downshifting from one gear to another, it might be due to a trapped open or closed shift solenoid. Fluid is channelled through the solenoids when the computer requests a downshift, therefore if a solenoid gets blocked, it is unable to properly transfer transmission fluid, resulting in the gearbox sticking in the same gear.
• Transmission Won’t Shift Out Of Neutral
If a shift solenoid breaks, the transmission will not be able to shift out of neutral. This results in the famed “6 neutrals” that the 4l60e is known for.
• Delayed or Irregular Shifts
If your shift solenoids fail, you may notice that the transmission shifts in an inconsistent and delayed way. Another possibility is that the transmission will try to seek down or locate the proper gear to be in. The computer tells the transmission to do one thing, but the transmission chooses gears on its own mechanically.
A Bad Shift Solenoid’s Important Codes
The check engine light will be on with one of the following diagnostic fault codes:
• Performance of P0751 1-2 Shift Solenoid Valve (Shift Solenoid A Performance).
• Electrical P0753 1-2 Shift Solenoid Valve (Shift Solenoid A Electrical).
• Performance of the P0756 2-3 Shift Solenoid Valve (Shift Solenoid B Performance).
• Electrical P0758 2-3 Shift Solenoid Valve (Shift Solenoid B Electrical).

• P0774 – Intermittent problem with the Shift Solenoid E.
Only 2nd gear is used by the transmission.
Running in LIMP IN MODE is what it’s called. When trying to determine if you have a solenoid problem or internal transmission damage (causing the transmission to stay in Limp-In mode), keep these two items in mind:
1. A transmission solenoid fault code will be placed in the PCM’s memory.
2. There is no ‘slippage’ in the transmission.
Now that we’ve got everything out of the way, let’s turn the page and start testing!
The shift solenoids on a 4l60e are positioned around where the pan bolts to the case on the back end of the gearbox. Once the pan and filter are removed, the shift solenoids are easily accessible as seen in the figure below. If you need to repair your shift solenoids, they’re a rather simple component to remove and replace.
On a 4l60e, how to test the shift solenoid.
A simple 9v battery may be used to test your shift solenoids to determine whether they are being actuated. A 9v battery and a pair of test leads are required for this procedure.
The first step in testing your shift solenoids is to remove the connectors that connect the solenoids to the harness. These are basic plugs with a tab that can be readily removed. If the plugs become stuck, jiggle them a little to loosen them up.
Take your test leads and attach them to the electrical prongs on the rear of the solenoid. It doesn’t matter which wire goes where because this is a solenoid. Simply connect your test leads to the 9v battery one at a time once they have been connected. When you connect the second wire to the battery, you should hear a clicking sound if the solenoid is working. Simply repeat the procedure for the other solenoid to ensure they are both operational.
Another technique to test your shift solenoids is to use a multimeter to measure the resistance in ohms.
How Can You Tell If You Have a Shift Solenoid Problem?
First, we must determine if the issue is with the wiring, shift solenoid, TCM, or mechanical components. To do so, study and investigate the trouble codes thoroughly to completely comprehend the issue before beginning troubleshooting.
It’s most likely a wiring or shift solenoid problem if the trouble code says it’s stuck or has an electrical problem.
Many shift solenoid-related errors can be cleared by replacing the transmission fluid or flushing the system. A transmission fluid replacement is frequently inexpensive and well worth the effort.
A diagnostic scanner is required when it comes to shifting solenoid troubles.
The following is a list of techniques to use a scanner to troubleshoot:
1. Find a transmission wiring diagram for your specific vehicle.
2. Determine which pins on the malfunctioning shift solenoid are connected.
3. Loosen and remove the transmission wire plug.
4. Using the OBD2 scanner, do an output test on the faulty shift solenoid.
5. Use a multimeter to see if the shift solenoid on the affected pin receives both 12 volts and ground at the transmission connector.
If you don’t obtain both 12 volts and ground, you could have a wiring problem or a faulty TCM ( transmission control unit ).
If you have 12 volts and ground but the shift solenoid error message keeps coming back after you’ve cleared it, you most likely have a defective shift solenoid.
What Does It Take To Replace A 4L60e Shift Solenoid?
It’s preferable to use high-quality ACDelco OEM replacement parts when replacing your 4l60e shift solenoids. The technique for replacing your 4l60e shift solenoids, if you haven’t already done so, is as follows:
• Drain transmission fluid
Draining transmission fluid can be as simple as removing a drain plug, or it can be more involved (and dirty) if there isn’t one.
• Remove Transmission Filter (Optional)
While this isn’t absolutely necessary, it does allow you to operate with greater space without striking it.
• Remove Clip Holding Solenoids
Using a pick or screw driver, remove the little c-shaped clip that keeps the solenoid in place. When the solenoid has been freed, you may now remove it.
• Wiggle and Pull Solenoid Out
Because solenoids are sealed by a rubber o-ring, all you have to do is wiggle and pull the solenoid out.
• Replace The New Solenoid and Repeat Steps 3 and 4 For The Second Solenoid
While you’re changing your shift solenoids, replace your transmission pan and filter as well, especially if you haven’t changed your fluid in a while or want a transmission pan with a drain plug for future convenience.
The cost of a replacement transmission 4l60e shift solenoid b
A single shift solenoid costs between $100 and $350 to replace, whereas a shift solenoid pack costs between $400 and $700 to replace, including transmission fluid, filter, components, and labor.
The cost of replacing a shift solenoid is significantly dependent on the vehicle and gearbox model.
As I previously said, just one solenoid may need to be changed in some cars. You’ll have to replace the entire solenoid pack or, in some situations, the entire valve body, which may be rather expensive.
Always change the transmission fluid and filter when replacing a shift solenoid, valve body, or solenoid pack.
These are the prices, which include both labor and components. The costs of diagnostic and fluid replacement are not included in the pricing.
• A single shift solenoid costs between $50 and $150 to replace.
• A replacement shift solenoid pack costs between $300 and $600.
• A valve body replacement might cost anywhere from $500 to $1000.
The parts and transmission fluid you use have a big impact on the price. Although aftermarket parts are occasionally less expensive than OEM parts, they are typically of worse quality.
Important 4l60e Shift Solenoids Suggestions and Tips
TIP 1: Before removing the transmission oil pan, read the section under “Before You Remove The Transmission Oil Pan.” To avoid any issues with the job’s completion, read this section completely.
TIP 2: Adjust the location of the solenoid. The letter A stands for shift solenoid 1-2. Shift solenoid B is the designation for shift solenoid 2-3.
TIP 3: Before removing the shift solenoids, make sure the car is completely cool. After the automobile is turned off, the transmission fluid warms up and remains hot for a long time. Be cautious and take all essential safeguards. Keep safety in mind at all times.
TIP 4: Even if the shift solenoids are fried, replacing them will not cure the problem if your gearbox is slipping.
Two Important Suggestions on 4l60 e shift solenoid b
To conclude this section of the article, before removing the transmission oil pan, I propose that you perform the following:
Before removing the transmission oil pan (from the transmission), wipe the sidewalls with carburetor cleaning spray (or brake clean spray). When you remove the old trans. fluid, the purpose is to get rid of any dirt or big particles that could fall into the drain pan (which you’re using to catch it).
• Clean your drain pan thoroughly. So, if you’ve been using this drain pan for purposes other than engine oil changes, make sure you clean it thoroughly.
• If you need to re-use the old transmission fluid, keep it clean by following the two suggestions below.
