Chevrolet Tahoe Transmission Problems & Solutions
Brief Chevrolet Tahoe History: In the mid 90s, every American wanted a full-size SUV. But the Chevrolet Suburban was just too long to fit inside an average McMansion’s garage. So General Motors lobbed 14-feet off the back of a Suburban, and created the first generation GMT400 1995-1999 Chevrolet Tahoe. The Jones’ loved this new right-sized kiddie hauler, and it soon became one of Chevrolet’s best selling models. A new GMT800 Chevy Tahoe was released for the 2000 model year, and it proved to be just as popular in the cul-de-sac’s of America. The GMT900 Tahoe was introduced for 2007, and this version of Chevy’s Private School Shuttle became a popular choice with law-enforcement and fire departments. The current K2UC Chevrolet Tahoe debuted for 2014, and while it’s much improved over previous generations, the economics of fuel consumption have caused sales figures to decline ever so slightly. It is still regarded as one of the most durable family vehicles on the market. However, it’s not uncommon to experience 4L60E transmission problems with earlier models, and 6L80E transmission problems with trucks made after 2009. So let’s pop the hood and see if we can’t find some affordable solutions.
Common Problems with the Chevrolet Tahoe 4L60E Transmission
Complete Failure of 3rd-4th Gear
One of the more common Chevy Tahoe transmission problems is the loss of 3rd and/or 4th gears. This occurs because the clutch discs inside the 4L60E 3-4 clutch pack have a tendency to wear out and fail prematurely. To keep this from happening to you, every remanufactured 4L60E transmission from Street Smart Transmission gets an upgraded High-Energy 3-4 clutch pack. The stock setup had just 6 clutch discs, but SST installs 7 4L60E clutch discs, which are made from much stronger metal. This upgrade will extend the Chevrolet Tahoe 4L60E service life, and it will be able to withstand higher engine torque as well.
Harsh and/or Delayed Shift Between 1st & 2nd Gears
If you’re experiencing a pause between the 1-2 shift, and/or the transmission seems to jerk or ‘bang’ into 2nd gear, then you’re probably experiencing another common Chevrolet Tahoe 4L60E transmission problem. It takes a lot of hydraulic pressure to change gears, so little parts called ‘accumulators’ are used to absorb the excess fluid pressure inside the valve body. However, the pistons inside the OE 4L60E 1-2 accumulators are made from plastic, and when they break, this problem will occur. That’s why every SST remanufactured 4L60E transmission has upgraded 1-2 accumulators, which feature stronger aluminum pistons. The entire valve body is also recalibrated to provide better fluid pressure control.
Common Problems with the Chevrolet Tahoe 6L80E Transmission
Overheating / Shifting Issues / No Forward Gears
Your Tahoe 6L80E transmission uses hydraulic pressure to translate engine power into motion. It’s up to the Pressure Regulator / PR system to maintain the perfect balance between too much and not enough pressure. Anything less than perfect, will result in any of the above Chevy Tahoe 6L80E transmission problems. To address many of the OE PR system design flaws, every SST remanufactured 6L80E transmission receives a number of critical upgrades, including stronger bushings, springs, check balls, and other critical PR system components. The entire valve body is also recalibrated to provide more consistent fluid pressure, more positive shifts, and less strain on the internal components.
How to Solve Chevrolet Tahoe Transmission Problems
Solution A: Buy a Used Chevrolet Tahoe 4L60E / 6L80E transmission
Money doesn’t grow on trees, so buying a used 4L60E or used 6L80E might seem affordable. But many of the inherent design flaws are likely to be present, and you really don’t know what kind of shape the internal components are in. There’s a very good chance that used transmission could have the same problems that you’re trying to fix now. And since that 30-90 day junkyard warranty doesn’t cover labor, you could be spending a lot more money than you thought.
Solution B: Buy a Rebuilt Chevrolet Tahoe 4L60E / 6L80E transmission
It might seem more prudent to invest in a rebuilt Chevy Tahoe transmission. However, that rebuilt 4L60E transmission / rebuilt 6L80E transmission will likely be built using an OE master rebuild kit. This contains all of the same parts the factory used to build your Tahoe transmission in the first place. Including those brittle plastic parts, and weak clutches. You can probably get a 1-2 year transmission warranty, but it may only be good at a small number of shops, in a specific geographic location. So if you have transmission problems, and you’re not close to one of the approved transmission shops. You could be shelling out a lot of money to fix the transmission that you just paid to fix.
Solution C: Buy a Remanufactured Chevrolet Tahoe 4L60E / 6L80E transmission
The best way to solve all of your Chevy Tahoe transmission problems is to opt for a remanufactured Chevrolet Tahoe transmission from Street Smart Transmission. Unlike a mechanic shop, or junkyard, each of our remanufactured 4L60E / remanufactured 6L80E transmissions have to undergo multiple quality inspections during each stage of the build. This ensures that every transmission is built correctly, with all of the correct parts. It also allows our quality inspection team to catch potential problems such as hairline cracks, or warping in the hard parts like the gear assemblies, or valve bodies. Every completed transmission is then hot and cold tested on a dyno machine, using a special program called C.A.R.S. (Computer Aided Road Simulation). This allows our technicians to check the operation of each transmission, and address any potential problems before it leaves the factory. Because of this dedication to quality, every Street Smart Transmission can be issued a Nationwide 3-year/Unlimited Mile Warranty. This will cover any necessary transmission repairs that are performed by any licensed repair shop, anywhere in the United States. It’s also linked to your truck’s VIN number, so you can transfer the coverage to a new owner if you ever decide to get a new kiddie/toy/client hauler.
