One of the most common questions we get here at Silverado Sierra is whether or not a Trailblazer transmission will fit in a Silverado. The answer is unfortunately, no. Though they may look similar, the two transmissions are not compatible with each other.
The two vehicles have different transmission types and sizes. The Trailblazer has a 4L60E while the Silverado has either a 4L80E or 6L80E. The Trailblazer is also slightly smaller than the Silverado, so the transmissions are not interchangeable.
This is due to the fact that the Trailblazer uses an entirely different engine than the Silverado. So, while you might be able to get the transmission to physically fit into the vehicle, it’s not going to work properly (or for very long).
Chevy Trailblazer Transmission Interchange Years
The Chevrolet Trailblazer is a mid-size sport utility vehicle that was produced by General Motors from 2002 to 2008. The Trailblazer nameplate was first introduced in 1999 as an upscale trim level of the Chevrolet Blazer, but became its own model in 2002. The Trailblazer replaced the Blazer in GM’s lineup and was marketed between the Chevy S-10 and the larger Tahoe.
The Trailblazer came standard with a four-speed automatic transmission, but could be ordered with a five-speed manual transmission in certain models. In 2006, GM began offering a six-speed automatic transmission as an option on some models. This transmission was not offered on all models until 2007.
The four-speed automatic transmissions used in the Trailblazer are interchangeable between all model years. The same is true for the five-speed manual transmissions. The six-speed automatic transmissions are also interchangeable between all model years, with the exception of early 2006 production vehicles which used a different bell housing bolt pattern than later vehicles.
If you are looking to replace the transmission in your Chevy Trailblazer, you should be able to find one from any model year that will work for your vehicle. Just be sure to check compatibility with your engine size and whether you need a 4×4 or 2WD version before making your purchase.

Does a Trailblazer Have a 4L60E Transmission?
The General Motors 4L60-E (and similar 4L65-E) is an automatic transmission that was designed and built by General Motors. The 4L60-E was introduced in 1992 in the GMC Yukon and Chevy Suburban with the 5.7 liter engine. The 4l60e is a heavier duty version of the popular 4l30e transmission found in many GM vehicles.
The main difference between the two transmissions is the gear ratios; the 4l60e has taller first, second, and third gear ratios for better towing performance. The fourth gear ratio is lower on the 4l60e than the 4l30e for improved fuel economy while cruising at highway speeds.
If you are looking for a trailblazer with a specific transmission then you will need to do some research on which model years came equipped with that particular transmission.
For example, early model TrailBlazers (2002-2003) came standard with a four speed automatic transmission called the 4L60E. Later model TrailBlazers (2004-2006) came standard with a five speed automatic transmission called the 5L40E. So if you’re looking for a TrailBlazer with a certain type of transmission then make sure to check what model year it is before making your purchase!
Are All 4L60E Transmissions Interchangeable?
There are a few different types of 4L60E transmissions, but they are generally interchangeable. The main difference is in the internals, such as the gear ratios and clutches. Some early 4L60Es had a different bolt pattern on the bell housing, but most late-model trucks use the same pattern.
You may need to swap over your transmission control module (TCM) if you’re going from an older to a newer model.
What Transmission Does a 4.2 Trailblazer Have?
The 4.2L TrailBlazer came standard with a 5-speed manual transmission, but could be optioned with a 4-speed automatic. The 4×4 model came standard with the automatic transmission.
What Size Transmission is in a 2004 Chevy Trailblazer?
The 2004 Chevy TrailBlazer comes with a 4-speed automatic transmission. This is the same transmission that is used in the 2003 model. The only difference between the two years is that the 2004 has an electronic control unit, or ECU, which controls the shifting of gears.
The ECU is located in the center console near the shifter. There are also two sensors on the transmission, one for each gear. These sensors tell the ECU when to shift gears.

Conclusion
If you own a Chevrolet Silverado 1500 and are looking to upgrade your transmission, you may be wondering if a Trailblazer transmission will fit. The answer is yes! A Trailblazer transmission can be easily installed in a Silverado 1500.
However, there are a few things to keep in mind before making the swap.
First, the Trailblazer transmission is slightly longer than the Silverado’s stock transmission. This means that the driveshaft will need to be shortened by about 2 inches.
Additionally, the shifter on the Trailblazer transmission is located in a different spot than on the Silverado’s stock transmission. Therefore, you will need to purchase a new shifter knob or have one custom-made. Overall, installing a Trailblazer transmission in a Silverado 1500 is relatively simple and can be done by most do-it-yourselfers.
Just be sure to take proper measurements and precautions before beginning the installation process.
