Why is my 4L60E not shifting into 4th gear?
Below are some common things that fail in the 4L60E and cause this problem. It probably goes without saying, but if you put the vehicle into second gear manually, you’ll still be able to get to where you need to go. If you end up with a bad sprag, the 4L60E won’t be able to shift into 3rd or 4th gear.
What causes the No 3rd or 4th gear problem?
One of the most common (and most frustrating) problems that happens to the 4L60E is when it loses 3rd and 4th gear at the same time. This leaves you driving around a car or truck that screams down the road. So, what causes the no 3rd gear or 4th gear problem?
What does it mean when transmission runs only in 2nd gear?
Transmission runs only in 2nd gear. This is known as running in LIMP IN MODE. The most important thing to remember, when trying to decide if you have a solenoid issue or internal transmission damage (causing the transmission to stay in Limp-In mode) is two very important things:
Can a bad clutch pack cause 3rd gear to stop working?
It’s referred to as the 3-4 clutch pack. A bad 3-4 clutch pack can certainly cause the 3’rd and 4’th gear to stop working. In fact, once the transmission “shifts” into third, it’ll feel like you lost the whole thing. You can shift into second to get yourself home. Just be careful on the highway.

The shop manual will show you the correct position. 3) No 3rd or 4th gear: If the 2 – 3 shift valve spring is missing, or someone has installed it wrong, you will lose 3rd and 4th gear. 4) No up shifting: This problem can be caused by the solenoid regulator valve being out of position.
What to do if your truck doesn’t shift into overdrive?
Turn the engine off and let it cool. Then turn the truck back on and initiate the same steps again. If the truck fails to shift into overdrive, there may be an issue with the sensor connecting the overdrive to the steering wheel panel.
What should I do if my gear shifter won’t shift?
There may be a failure with the connections between the gear shifter and the dashboard mechanism. Shift into drive and drive forward slowly at first, accelerating more as you move. Check to see if the Revolutions per Minute (RPM) reaches 3,000 before shifting gears, or if it goes higher to 4,000 or 5,000 and then shifts.
What happens when the Overdrive is off on a Dodge Ram?
When the overdrive is off, the truck operates on three gears, allowing it to pull more weight and giving it more power. When the overdrive is on, the truck operates on four gears, using less power and less gas.
Why does my car not shift into third gear?
Such a problem is automatic transmission won’t shift into 3rd gear. The transmission shifts into the first and then to second gear but does not move into the third gear. It seems that the gear slips into neutral when you push it to the third. Another instance could be the automatic transmission won’t shift into 3rd gear at all.
Why is my car not shifting into reverse?
This is large, maze-like component that directs the flow of hydraulic fluid to the valves. This is what allows a car to smoothly shift gears whenever the situation calls for it. In case of a bad transmission valve body, you may experience delayed shifting into reverse or simply nothing happening after shifting in reverse and stepping on the gas.
Can a Ford Expedition shift into 4th gear?

2. 1-2 shift does not happen at WOT (Wide Open Throttle) until you let off the gas: Best case: try replacing the TPS. Middle case: leak in the 2nd gear apply circuit (servo assembly or 1-2 accumulator). Double check by using the pressure gauge and watch for a big drop when the PCM commands 2nd gear.
Why does my 4L60E have no reverse?
Slow, slipping or no reverse: “lo-reverse” clutches are worn out, fluid leak in the reverse apply circuit, or broken sunshell.
Why is my Toyota 4Runner not shifting correctly?
This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

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.

What happens when you shift your transmission hard?
When the transmission shifts hard, it can damage internal components including valve bodies, hydraulic lines, and in some cases mechanical gears. If you notice your transmission is shifting harshly or roughly, you should contact a local ASE certified mechanic as soon as possible.
Can a bad speed sensor affect shift timing?
Harsh or improper shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing,…
What causes a harsh shift on a 4R44E?
From the same circuit the complaint can be delayed reverse, flare 1-2 or 2-3, and harsh shifts following a forced downshift. The harsh shifts occur because the EPC “booster” valve gets stuck at maximum flow. EPC circuit problems also cause broken bands and servo piston seal blowout.
