The 4L60E is a four-speed automatic transmission, which at some point may present some faults that must be solved as soon as possible.. Knowing the signs, symptoms, and solutions of a failed transmission can help you avoid a real headache.
In this article you will find the 10 warning signs and causes of a bad 4L60E transmission along with some solutions.
What is the 4L60E transmission?
We begin by stating that this transmission series is a four-speed automatic transmission, which includes four forward gears and one reverse gear.
General Motors began producing the 4L60E to replace the 700R4 transmission, marking the first time the company had moved away from hydraulically controlled transmissions and incorporated an electronically controlled model into its vehicles.
What you should know:
- The four indicates four gears forward, which means it’s a four-speed transmission.
- The L means that this transmission has longitudinal applications, which means it includes rear-wheel drive.
- The 60 means the torque value it has. With this amount of torque, the vehicle should be able to safely move almost three tons
- The E stands for electronically controlled shifting. This feature offers many benefits, such as smoother engine output and better control of the car.
- The 4L60E series of transmissions remained in production for more than two decades, from 1992 to 2013.
The 10 most common failures with the 4L60E transmission
It is true that the 4L60E transmission is one of the best, but it is not without its faults. Unfortunately, transmission problems have been said to occur with even the best care and maintenance.
We have selected some of the most common problems that affect the 4L60E transmission. We also offer possible causes, settlements, and costs for your convenience.
4L60E transmission third gear failure
The most common gear problem is the loss of third gear. It is important to note that this failure usually occurs out of the blue. You can put the car in gear and shift into second with no problem, and just as you try to shift into third, nothing happens.
To fix this problem, automotive experts believe you’ll need a new piston and clutch.
- This problem occurs because the rubber piston seals have shrunk from age and heat.
4L60E transmission reverse and second gear failure
Another common problem is the inability to shift into second gear or back up. This fault usually appears when the casing of the drive is broken.
You can fix this fault by replacing the drive casing. You should be aware that replacing the drive casing means you will have to remove the transmission and rebuild it.
- A new drive cage can cost you anywhere from $50 to $100
4L60E Transmission Hard Second Gear Failure
The third problem is the difficulty in shifting to second gear. You will be able to identify this problem by feeling that you need to apply more force when shifting into second. This failure usually occurs when the TCC throttle valve wears out.
You will be able to fix this fault by changing the regulator on the TCC valve. To replace the TCC valve regulator, you will need to remove the fan and filter. Then remove the solenoids, wiring harness, and bolt from the valve body. Next, lift up the valve body and turn it over.
4L60E Third or fourth gear transmission loss problem
In this section we indicate that a complete loss of third or fourth gear can occur. If you can’t shift into third or fourth gear, a worn clutch is often the cause of this issue.
The solution will be to replace the clutch. A professional or specialist mechanic should perform this repair.
4L60E Loss of transmission of all gears / faulty pump
This problem usually occurs if your car experiences a total loss of fluid or if the pump fails.
To fix it you must first check the fluid levels in your vehicle. You must turn off the engine before doing this. If the fluid levels appear correct, start the engine and double check the levels.
You’ll know the pump is broken if the fluid levels don’t drop while the engine is running. If the pump is broken, it will need to be replaced.
4L60E transmission slip failures
A common fault for all types of transmissions, andSlippage occurs when transmission fluid problems occur. For example, transmission fluid problems can occur when the fluid level is low.
Common slip indicators can include burning odors and annoying metallic noises such as groaning or grinding.
To fix this problem, you will need to check the fluid level by removing the dipstick and determining if the levels are low. If the levels are low you can try topping up the fluid and see if that resolves the issue.
4L60E Transmission Noise Faults
The most common cause of this problem is a lack of lubrication.. Usually, shifting to neutral or third gear will make the problem go away. This is just a momentary breather though, and the noise will return when you shift back into first or reverse gear.
The transmission will need to be removed and rebuilt to fix this issue. A professional mechanic or specialist will need to determine the exact cause.
4L60E Transmission All Fluid Pumped Through Vent Problem
In the event that your 4L60E transmission experiences this failure, it is most likely due to a blocked coolant line or an overfilled transmission.
You can fix this problem by flushing the transmission cooler to remove the blockage. While there are various solvents for cleaning the transmission cooler, they do not always clear the clog.
4L60E transmission without overdrive problem
Overdrive is essentially fourth gear, which can arise due to various issues; Causes of this issue range from linking issues to band failure. To determine if the problem is simply a linkage problem, you can try changing the OD to D, 2, and then 1.
The transmission will need to be removed and rebuilt to fix this issue. Because there are multiple causes for this issue, a professional mechanic or a specialist will need to determine the exact cause.
Faults with 4L60E Transmission Shift Solenoid
If your 4L60E transmission is experiencing any of the following faults, the most likely cause could be your solenoid. A faulty solenoid can cause problems like erratic shifting, failing to downshift, or getting stuck in neutral.
The transmission will need to be removed and rebuilt to fix this fault. Since there are multiple causes for this problem, a professional mechanic or specialist will need to determine the exact cause.
- The average price of a new solenoid can cost anywhere from $40 to $100
