The Chevy Silverado 1500 4-speed 4L60E and 4L65E was able to handle the power of the various 4.8L, 5.3L, 5.7L and 6.0L engines while still providing impressive fuel economy. The next generation Chevrolet Silverado 6L80 transmission came in 2005. It featured more advanced electronic controls, and the ability to handle the increased torque found in the 1st, 2nd, and 3rd generation Chevy Silverado 1500. But they aren’t without their problems though, so let’s look at some of the most common Chevy Silverado 1500 transmission problems, look at cost estimates and figure out what you can do about them.
From the 1970’s to 1998, the name ‘Silverado’ was used to designate the top trim model of the Chevrolet C/K truck line. For 1999, the all new truck was called simply the Chevrolet Silverado, and the trim lines were changed to LS, LT, Silverado Z71 etc. Building on the popularity of the first generation GMT800 Silverado, the second gen GMT900 Silverado offered improved build quality, bigger towing capacity, and more efficient engines. The latest K2XX Silverado brings the Chevy workhorse into the 21st century with a fully boxed hydroformed high-strength steel frame, available built-in Wi-Fi, and an all new 8-speed automatic transmission. Does something seem wrong with your Silverado? Let’s look at some of the most common Chevy Silverado transmission problems, and see what you can do to get your car back on the road.

What are the DTC codes related to Silverado 1500 transmission problems?
P0766 – Failed Shift Solenoid D – This DTC can be stored when there is a problem with a shift solenoid or the valve body.
P2703 – Failed Friction Element D – This trouble code can be triggered by a failed friction element like a clutch disc.
P0720 – Failed Input Speed Sensor or Output Speed Sensor – This trouble code is caused by a bad speed sensor on the transmission.
P0730 – Incorrect Gear Ratio – This issue could be caused by a number of problems, including a fault in the transmission control module, dirty transmission fluid, or a bad transmission solenoid.
P0657 – Voltage Problem in the ‘A’ Circuit – This transmission problem is often caused by a short, or bad ground on the PCM or PCM wiring harness.
P0700 – Malfunction in the transmission control system – This DTC is often triggered when there is a problem with the TCM, a wiring harness, a solenoid, or the valve body.
P0715 – Input/Turbine Speed Sensor Malfunction – This code typically gets stored when the input sensor cannot read the engine RPM, which can prevent the transmission from appropriately shifting gears.
P0717 – Input/Turbine Speed Sensor No Signal – This trouble code is generated when the PCM does not get a signal from the input speed sensor, which will prevent the computer from being able to determine when the transmission needs to shift.
P0791 – Intermediate Shaft Speed Sensor ‘A’ Circuit – This error can occur when there is a problem with the intermediate shaft speed sensor, most likely due to a bad sensor, wiring problem, or a failed shift solenoid.
P0793 – Intermediate Shaft Speed Sensor Circuit No Signal – The computer will generate this DTC when it cannot communicate with the intermediate shaft speed sensor.
Chevrolet Silverado Recalls
Recall ID – NHTSA: 14V152000 – 2014 Silverado 1500
In March 2014, General Motors recalled certain 2014 model year Chevrolet Silverado Light Duty Regular Cab, Double Cab, and Crew Cab 1500 series trucks equipped with the 6-Speed Automatic Transmission (feature code MYC). The recalled trucks may have a transmission oil cooler line that is not securely seated in the fitting.
If the line is not securely seated and transmission oil leaks from the fitting, the oil could contact a hot surface and cause a vehicle fire.
Dealers were instructed to inspect the transmission oil cooler line connection and repair the vehicles, as needed, free of charge. Owners may contact Chevrolet at 1-866-694-6546 (refer to the Chevrolet Silverado recall 14121) or the National Highway Traffic Safety Administration at 1-888-327-4236 (refer to recall 14V152000).
Recall ID – NHTSA: 13V001000 – 2013 Chevrolet Silverado 1500 / 2013 1500 Hybrid / 2013 2500 HD / 2013 3500 HD
In 2012, GM recalled the 2013 Silverado HD, Silverado LD, Suburban, and Tahoe; manufactured between November 7, 2012, through December 18, 2012, for failing to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 102, “Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect”, and FMVSS No. 114, “Theft Protection and Rollaway Prevention.” These trucks may have been built with a fractured park lock cable or a malformed steering column lock actuator gear in the lock module assembly.
As a result of this manufacturing defect, the Silverado may shift from ‘Park’ with the ignition key removed or the ignition key in the OFF position. These trucks may also shift out of Park without application of the brake pedal while the key is off. Either of these scenarios may cause the truck to roll away after the driver has exited the vehicle, resulting in a possible crash and/or injury.
Chevy dealers were instructed to replace the steering column as necessary, free of charge. Owners can call Chevrolet at 1-800-630-2438 (refer to the Silverado recall 12331) or the National Highway Traffic Safety Administration at 1-888-327-4236 (refer to recall 13V001000).
Chevrolet Silverado Technical Service Bulletins (TSB)
2007-2008 TSB PIP4112E
On gas-powered trucks, owners may experience a hesitation when aggressively applying the throttle after coasting with a closed throttle. Trucks equipped with the 6L80 or 6L90 transmission may experience the same hesitation after making a hard stop with a closed throttle, then aggressively applying the throttle.
According to Chevrolet, the first condition is the result of the Torque Management software, which slowly opens the throttle for 0.7 seconds to minimize driveline lash and ‘clunking’. The second condition may occur because the 6L transmission downshifts may not be complete when the throttle is reapplied. In this case, the computer delays engine torque application for 0.5 seconds to allow the transmission to engage first gear.
2010-2013 Silverado – TSB P10488C
Trucks equipped with the 6-speed 6L80 or 6L90 transmission may experience no forward or reverse engagement, or slipping between the gears.
This problem could be caused by a cracked or split transmission filter. If this is the case, the fluid pump should be disassembled and inspected for possible damage. Inspect for any of the following conditions: – scored pump rotor or pump vanes – scored pump cover or pump rotor pocket – cracked pump slide.
The transmission should also be evaluated for any possible distress to the clutches. GM’s testing and analysis found that split or damaged filters may be caused by a damaged pump. This can send a high pressure fluid spike down the filter neck on a cold start, resulting in the filter body cracking or the filter seam splitting. The filter is not defective and this is not a filter quality issue. Important: Do not replace the filter without inspecting the pump. Failure to inspect the pump and clutches could lead to a repeat of this condition.
2008 Chevrolet Silverado HD – TSB 14308
Diesel powered 2008 Silverado HD trucks equipped with the Allison 1000 6-speed automatic transmission (RPO MW7), may have a condition in which increased transmission oil cooling circuit pressure may cause transmission fluid to weep or leak. This loss of fluid occurs near the transmission cooler at the crimp joints on the metal ends of the cooler line where it joins the rubber hose. The increased oil cooling circuit pressure typically occurs while driving in extremely low temperatures.
Inspect and replace cooler lines if necessary.
2012-2015 Chevrolet Silverado – TSB PIT5206B
These trucks may experience unwanted grade braking when not going down a grade, reduced/low engine power with no DIC messages or DTCs (Brake Pedal Override Feature), erratic shifting or frequent up and down shifts with no DTCs. These issues may be caused by the Brake Pedal Position (BPP) sensor not being learned correctly in the ECM (Engine Control Module).
The ECU will have to be reprogrammed.
2007-2008 Silverado – TSB 09-07-30-004J
Trucks equipped with the 6L80 or 6L90 transmission may slip when Reverse is selected or have no/delayed reverse engagement, harsh shifts from 2-3 / 4-5 or slips while in fifth, and slipping acceleration when passing. Possible DTCs include P0776, P2715 or P2723.
This problem may be caused by a cracked 1-2-3-4 / 3-5-R clutch housing.
2012 Silverado HD – TSB 14043
Certain 2012 Silverado HD trucks equipped with the Allison 1000 6-speed automatic transmission (MW7), may have been built with an incorrect transmission thrust bearing. Over time, this bearing could fail, resulting in noise and poor transmission operation.
The bearing should be replaced with GM part # 29531106
Common Problems with the 1500 4L60E / 4L65E Transmission (Most Early Models 2011-Down)
1) Faulty 1-2 Accumulator
If you experience a delay, shudder, or extreme harshness during the 1-2 shift, it may be due to a faulty 4L60E 1-2 accumulator. This little device acts as sort of a shock absorber for the fluid pressure that builds inside the valve body, once the solenoid triggers a shift. The OE 1-2 accumulator piston is made from plastic, and it has a tendency to break. That can cause this most common 4L60E transmission problem, along with premature clutch failure. To keep that from happening, the Street Smart remanufactured 4L60E transmission is fitted with aluminum 1-2 accumulator pistons, along with a recalibrated valve body for better fluid pressure control.
2) 3-4 Clutch Failure
Another common Silverado 1500 transmission problem is the total loss of 3rd and 4th gears. This happens because the discs inside of the 3-4 clutch pack are known to wear out prematurely. To avoid this, Street Smart Transmission installs a High-Energy 3-4 clutch pack In every remanufactured 4L60E transmission. It features an extra clutch disc (7 total) to improve not only the durability, but the amount of torque that the transmission can handle.
Common Problems with the Silverado 1500 4L80E Transmission (1500 HD Only)
1) Failed Shift Solenoids
In order for the computer to control the hydraulic shifting systems, it sends an electrical charge through a coil of wire that’s wrapped around a plunger device called a solenoid. A total of 8 shift solenoids are positioned throughout the valve body, and it’s their job to direct the pressurized ATF/hydraulic fluid to the correct channel to actuate a gear change. If one of these solenoids go bad, you may experience slipping between gears, failure to shift, and a failure to shift into overdrive.
There’s a bunch of moving parts inside your Silverado 2500 4L80E transmission, and its up to the transmission fluid to keep everything cool. Towing heavy loads, and the constant shifting that occurs in stop-and-go traffic and mountainous terrain can intensify the heat, which can cause the transmission to literally overheat. This can result in blown transmission seals, along with damage to the clutches, bands, and valve body. To keep this from happening, we recommend installing an auxiliary transmission cooler.
Common Problems with the Silverado 1500 6L80 Transmission (Most Late Models 2007+)
Pressure Regulator System: An automatic transmission relies on hydraulic pressure to move parts around and propel you down the road. This pressure is maintained by the 6L80 pressure regulator / PR system, which uses a series of springs, valves, and check balls. Some of the plastic and lower-grade metal pieces tend to wear out prematurely, causing all sorts of issues. You may see harsh shifts, soft shifts, failure to engage Drive, slipping in-and-out of gear, and overheating.
Can I drive with a transmission problem?
Okay, if your truck can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.
How often does a Silverado 1500 transmission need to be replaced?
The overall lifespan of a Silverado 1500 transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the OE Silverado 1500 4L60E transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.
How are Chevy Silverado 1500 transmission issues diagnosed?
It is fairly easy to guesstimate what the root cause of your Chevy Silverado 1500 transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.
How is a Chevy Silverado 1500 transmission replaced?
In order to replace your Chevy Silverado transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed. Once it is in place, for the 6L80, the vehicle PCM will have to be reprogrammed to accept the new gearbox.

How to Solve Chevy Silverado 1500 Transmission Problems
Solution A: Buy a Used Chevy Silverado 1500 Transmission
The quickest way to fix your transmission problems is to simply buy a used 4L60E transmission or used 6L80 transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.
Solution B: Buy a Rebuilt Chevy Silverado 1500 Transmission
Another option would be a rebuilt 4L60E transmission or rebuilt 6L80 transmission. A local repair shop will remove your 1500 transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.
Solution C: Buy a Remanufactured Chevy Silverado 1500 Transmission
Many owners depend on their Chevy Silverado to make a living and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured 4L60E transmission or remanufactured 6L80 transmission.
