The 4LE is an automatic shift, four-speed overdrive, longitudinally positioned transmission. It has been considered to be the best rendition of the finest overdrive automatic transmission ever produced.
The Late 4LE was released in in and fully phased into wide use through GM by in both RWD car platforms including the C6 Corvette and trucks in both 2wd and 4wd configurations. The 4L60E transmission weighs pounds dry, and wet. It requires 8.
This list is merely a guide to the possible solutions. It is possible to remedy a fluid problem by removing the checkball from its cage in the case in the rear of the transmission may help must remove valve bodyor adding a high-viscosity additive or other seal restorer product.
May also have worn boost valve can replace in the pan. Middle case: leak in the 2nd gear apply circuit servo assembly or accumulator. Double check by using the pressure gauge and watch for a big drop when the PCM commands 2nd gear. Worst case: poor line pressure rise see below. Check the yellow spring inside the accum housing for breakage.
Also, if the accumulator housing walls are scored, the housing must be replaced. If not, this must be replaced. Trans does not upshift out of first, speedometer reads zero at all times: Could be VSS failure. Rear of transmission needs to be fixed. Transmission needs to come out in order to access VSS. The car is safe to drive in 2 until you can get it fixed. Sudden grinding noise with no prior warning primarily in 2nd gear, behavior in reverse may be abnormal: sunshell is fractured.
Must be removed and rebuilt. Try not to run or drive the car or further damage could result. Transmission must be removed and rebuilt.
No 2nd or 4th gear. Otherwise, band is worn out. Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the underhood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust.
Needs diagnostic testing. Horrible noise in 4th and feels like the brakes are on: overrun clutches are applying due to a cracked or leaking forward piston.
Overrun clutches will be worn out after 30 seconds of this behavior. Car can be safely driven in D.Modern automatic transmissions use hydraulic fluid, which is activated by solenoids, to shift gears.
In the 4L60Eshift solenoid problems can cause a lot of trouble. The purpose of this article is to help you identify 4L60E shift solenoid symptoms.
It means electronic control. The shift solenoids are the means by which this control is physically achieved within the transmission. Shift solenoids are relatively basic in design and principal. Simply put, the shift solenoid has a spring loaded plunger inside of it that will move transmission fluid in and out of different parts of the transmission. This action makes the transmission shift into different gears.
This is due to the fact that the transmission fluid cannot be rerouted to the part of the transmission that would be making the next move. To put it simply, it is stuck doing what it was doing when the solenoid failed. The transmission will skip gears. In this situation the transitional will remain a neutral regardless of what gear you put it in.
Most of the problems that occur with a 4L60E shift solenoid are caused by the coil wire going bad in some way.

It can go bad in a couple of ways. The plunger can also get stuck. You can test the solenoids with an OHM meter. You should be looking for ohms of resistance.
If no resistance is found, than you know that the solenoid is bad, and that it is broken. Unlike when the shift solenoids are melted or broken, a stuck plunger can be repaired. Shift solenoids are not expensive. It would be a good idea to replace it if you can afford it.
This will keep you from getting under the truck next time the plunger decides to get stuck. A stuck plunger is almost always caused by dirty transmission fluid or debris in the case. What do shift solenoids do in the 4L60E? This movement is achieved through the creation of a magnetic field within them.The descendent of the R4, the 4L60E trans has a long history of backing up some fairly potent motors.
InGM started using the 4L60E in all rear-wheel drive cars, until when performance demands had increased beyond its current capacity, and it was replaced with the 4L65E. The 4L65E was built on the same platform as the 60, but with a few differences. The 4L60E uses 4-pinion planetary carriers, these carriers are rated to ft. The 4L65E utilizes 5-pinion planetaries, along with a hardened input shaft, that boosted torque capacity to ft.
The nice thing about all of this is that the 5-lug parts are easily swapped into the 4L60E, leaving you with the ability to upgrade your existing tranny without having to buy a new unit. Replacing the planetary carriers requires a full teardown. If you have never done this before, this may not be the time to start. This is not the most difficult tranny to build but it is certainly not the easiest.
And there are a few specialized tools needed to correctly complete the job. Inwhen the 4L60E was introduced, the R4 was renamed 4L This is important as while they share some parts, they are different transmissions. This type of lockup circuit offers a smoother transition as it pulses the signal instead of all at once.
The important thing to remember here is that the tranny type, PWM or non-PWM, must match the computer in the car, otherwise it will not function properly.
Since the upgrade requires a complete teardown, a full rebuild, with a few extra performance pieces, is a good idea. There are a few areas that require special attention and are commonly overlooked. The Pump Pressure Relief is the 1 cause of failure after overhaul. It is very easy to forget this little ball and spring, but it tends to get gummy and starts sticking.
For this rebuild, we used several kits. We cherry picked the clutch kit, using the Z-pack for the gear clutches. These are specifically designed to not bow and have superior holding power. The Red-Oxide clutches have better hold for Another piece that is a must in any high-performance transmission, is a beefy sun shell gear. It is integral in 2 nd and reverse application.
The stock parts have a tendency to sheer off the gear at the neck in high-performance applications. This unit is made of overall thicker material and includes a new thrust washer. Here is the meat of the conversion, the 5-pinion rear planetary. In high-performance applications, the rear planetary carrier carries all the stress. Upgrading to the 5-pinion unit offers the ability to hold much higher torque values.
The 4L60E also uses a 4-pinion front planetary carrier, which is more expensive than the rear unit. Upgrading to the 5-pinion front carrier is advisable in towing applications and where horsepower numbers are above Your question may be answered by sellers, manufacturers, or customers who purchased this item, who are all part of the Amazon community.

Namely, six NFL games feature two teams facing off that are (a) currently in the playoff picture or (b) just one game out of the playoff race.
We'll take a deeper dive into those six matchups below. Furthermore, you can find odds (via OddsShark) and props (via OddsChecker) for each Week 13 game, in addition to some picks. Detroit Lions at Baltimore Ravens (-2. Danny Woodhead and Buck Allen should also create havoc in third-down situations, as their pass-catching prowess should give the Lions fits. But the game will be won between the tackles. Look for Collins to cross the century mark as the Ravens control the time of possession and win a low-scoring matchup.
The Atlanta Falcons are on a roll after winning three straight games, but they are banged up in the defensive backfield heading into a crucial matchup with the Minnesota Vikings.
Of note, cornerback Desmond Trufant suffered a concussion and will not play. Fellow corner Brian Poole only turned in one limited practice this week and is questionable. Against the superior tag-team duo of Adam Thielen and Stefon Diggs, the Falcons need all hands on deck to hang with the fantastic Viking pass attack.
Without Trufant (and maybe Poole), it could be a long day for the Atlanta defense. The New England Patriots can win this game however they want.
If they prefer to go to the ground and give the ball to running backs Dion Lewis and Rex Burkhead close to 40 times, they'll be successful.
If they want to go long to deep threat Brandin Cooks, they should be fine. If they want to feed tight end Rob Gronkowski in his annual homecoming game in Western New York, they can do that, too.
That's less of an indictment on the Buffalo defense, which has been up and down (sometimes very down) all year but has overall surpassed low preseason expectations.
Rather, it's a commentary on the fact that the Pats are firing on all cylinders after winning seven straight. The guess here is that this game becomes an "anything you can do, I can do better" matchup between the Carolina Panthers' No. When these two teams played in September, Thomas had five catches for 50 yards and one touchdown on the first drive alone. He didn't see many targets the rest of the way as the Saints were largely in command of the matchup and went to the ground, but Thomas showed he can beat the Panthers secondary.
As for Funchess, he is facing a Saints team that is missing safety Marcus Williams and may not have cornerback Marshon Lattimore, who is questionable with an ankle injury. Ken Crawley is back from an abdomen injury, but as he told Josh Katzenstein of NOLA.
Philadelphia Eagles at Seattle SeahawksIf the Seattle offensive line can hold off the Philadelphia Eagles' front seven long enough for quarterback Russell Wilson to do work, then the 'Hawks can protect their house and pull off the upset. If the Seahawks falter in that regard, then it could be a long day for the Seattle offense.
