Chevrolet Silverado Transmission Problems & Solutions
GM completely changed the pickup game when it launched the redesigned Chevy C/K in 1988. It was modern looking, it had a plush interior, and all of the technology was cutting edge. To keep up with the times, the 4-speed 700R4 transmission was replaced for 1993 with the electronically controlled 4L60E. This gearbox offered better performance while simultaneously improving fuel economy. The next Chevrolet Silverado transmission came in 2005, with the introduction of the 6-speed 6L80. 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. Both transmissions aren’t without fault however, so let’s look at some of the problems that you might experience.
Common Chevrolet Silverado 1500 4L60E Transmission Problems
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.
3-4 Clutch Failure
Another common Silverado 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 Chevrolet Silverado 1500 6L80 Transmission Problems
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. To extend the service life of this critical system, every Street Smart remanufactured 6L80 transmission receives upgraded PR system components (made from stronger materials), and a recalibrated valve body to maintain more consistent fluid pressure.
How to Solve Chevrolet Silverado Transmission Problems
Solution A: Buy a Used Chevrolet Silverado 4L60E / 6L80 transmission
The easiest way to fix a Chevy Silverado transmission problem is to replace the transmission itself. Buying a used 4L60E transmission, or a used 6L80 transmission from a salvage yard would be the most economical way to go. However, the junk yard has no way of knowing the condition of the internal components, so you could be purchasing the exact same problems, or worse. Plus, that 30-90 day warranty won’t cover installation/labor charges if something goes wrong, which could make that used Silverado transmission quite expensive indeed.
Solution B: Buy a Rebuilt Chevrolet Silverado 4L60E / 6L80 transmission
If you don’t want to risk buying someone else’s problems, you could opt for a rebuilt 4L60E transmission, or a rebuilt 6L80 transmission. These have been torn apart, and most of the key components get replaced. The overall quality however, is dependent on the skills and experience of the tech rebuilding it. You will typically get a 1-2 year warranty on a rebuilt Chevrolet Silverado transmission, but it may only be honored at certain shops, within a specific region.
Solution C: Buy a Remanufactured Chevrolet Silverado 4L60E / 6L80 transmission
Your third, and best option would be to buy a remanufactured 4L60E transmission, or remanufactured 6L80 transmission. These are completely remanufactured in our state-of-the-art factory, and any parts that don’t meet specification are immediately replaced. Everything from the valve body to the torque converter are thoroughly remanufactured back to, or exceeding OE specifications. Current updates and upgrades are installed, and the Transmission Control Module is reprogrammed with the latest software version available from GM. Once the transmission is reassembled, it’s hot & cold tested on a dyno machine, to ensure that it performs properly before it gets shipped to your installer. It’s also given a 3-year/Unlimited Mile (18-months/100,000 miles for commercial and heavy duty applications) Warranty, that covers parts and labor at any licensed repair facility in the country. In addition, the Street Smart Warranty is linked to your Silverado’s VIN number, which allows you to transfer coverage to a new owner, if you decide to sell the truck.
