Can I drive with a transmission problem?

Many Chevrolet Silverado 3500 transmission problems will start out small, and many people will choose to continue driving until it’s convenient to have the repair made. But doing that is the financial version of playing Russian roulette. If the transmission problem turns out to be no big deal, then you are fine. However if the problem grows, or creates new problems, then you could be staring down the barrel of a really big repair bill.

How often does a Chevy Silverado 3500 HD transmission need to be replaced?

Obviously, the way you drive and take care of your truck has a lot to do with how long your gearbox will last. The average lifespan of a stock Silverado 3500HD transmission we’ve seen is:
4L80E – 120,000-180,000 miles
6L90 – 130,000-200,000 miles
Allison 1000 – 160,000-220,000 miles

However, if you invest is a remanufactured Silverado 3500 transmission that has had all of the factory design flaws addressed, you could get considerably more mileage.

How are Chevy Silverado 3500 HD transmission issues diagnosed?

Diagnosing most Chevrolet Silverado 3500 transmission problems is a fairly simple affair; plug a diagnostic computer into the OBDII port under the dash, read the diagnostic trouble codes, verify the source of the problem with a visual inspection. Sometimes however, a mechanic may have to put their sleuthing skills to the test if there are no DTC’s related to the problem.

How is a Chevy Silverado 3500 HD transmission replaced?

Because it’s a RWD/4WD, body – on – frame truck, replacing a Chevrolet Silverado 3500 transmission isn’t all that complicated. Once the driveshaft has been removed, the transmission can be unbolted from the engine and frame, then lowered to the ground. Installation is the reverse of that procedure. However, the ECU/TCM will need to be reprogrammed to accept the new transmission.

How to Solve Chevy Silverado 3500 HD Transmission Problems

Solution A: Buy a Used Chevy Silverado 3500 HD Transmission

The quickest way to fix your transmission problems is to simply buy a used transmission or used 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 3500 HD Transmission

Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your 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 3500 HD Transmission

Many owners depend on their vehicle to commute 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 transmission.

ITS LEAKING FLUID 2001 SILVERADO K 3500 220,000 NEVER RUN HOT ALWAYS CHANGED FLUID AND FILTER

Scott A

2018 Silverado 3500HD Duramax/Allison combo:

While driving in the morning (just leaving house) or if it’s sat for a while, the tranny surges like a shake, shake, shake feeling while driving at a steady speed. While driving at high speeds and decelerating quickly, the truck slows but the tranny isn’t keeping up with RMP highs/lows. At the point of stopping, it hard-shifts down.

Are there any reports of this happening elsewhere?
