Remanufactured GMC W3500 Transmissions 

 

Should you need to get some serious work done, the GMC W3500 Tilt Master is hard to beat. However, transmission problems with the 4L80E could leave you wanting for more. So let’s find out if a remanufactured GMC W3500 transmission could help you get back to the job site quicker. 

 

Common GMC W3500 4L80 Transmission Problems  

 

Erratic Shifting 

Since this was an early electronically controlled transmission, many shift problems/Check Engine Lights can be attributed to a failed input/output speed sensor, or throttle position sensor. 

 

Slipping Between Gears/Failure to Shift 

The 4L80E uses a total of 8 solenoids to actuate gear changes, and activate the lockup torque converter. These little plungers are used to control the ATF fluid pressure, and theyre activated by an electric charge that passes through a coil of wire thats wrapped around the plunger mechanism. If excessive vibrations or an electrical surge causes the solenoid to short out, youll start to experience serious problems. 

 

Overheating 

The primary function of automatic transmission fluid is to remove heat from the moving parts inside. If youre towing/hauling a heavy load and the radiator cooler cant properly cool the ATF, the transmission will overheat, causing significant damage to the valve body, seals, clutches, bands, and other parts. 

 

How to Solve GMC W3500 Transmission Problems 

 

Solution A: Buy a Used GMC W3500 Transmission  

Going to the local junkyard and picking up a used GMC W3500 transmission might seem like the cheapest and fastest option. But you need to consider the fact that you don’t know what the actual shape of the internal components are. It could very well be on the verge of transmission problems of its own, which would leave you in the exact same predicament that you’re in now. And that 30 – 90 day junkyard warranty probably won’t cover labor charges to install the replacement transmission if something goes wrong. 

 

Solution B: Buy a Rebuilt GMC W3500 Transmission  

Getting a rebuilt GMC W3500 transmission would probably seem like a better idea. However, a lot of mechanics and transmission shops will only rebuild your GMC W3500 transmission back to its original factory specifications. Which means that all of those factory design flaws are still going to be inplay. And that rebuilt transmission warranty might only be good at certain shops, which could do you no good if you have transmission problems while you’re traveling. 

 

Solution C: Buy a Remanufactured GMC W3500 Transmission  

If you want to get the most service life out of your little luxury SUV as possible, then you really should consider a remanufactured GMC W3500 transmission from Street Smart Transmission. Each one is completely disassembled and re-remanufactured, so nothing is left to chance. Theyre also modified to correct the factory design flaws, which will greatly extend the service life. Plus, you get a 3-Year/Unlimited Mile Nationwide Warranty. This will cover parts and labor charges at any licensed repair shop in the Continental United States, giving you a lot more flexibility and coverage.
