The GMT 199 names are applied to GM U-based minivans, includes the Chevrolet Lumina APV, Oldsmobile Silhouette and Pontiac Trans Sport were 1st made in 1990 to 1996. North American minivans were succeeded to GM U-body/GMT200.
The GMT 200 names are applied to the GM U-based minivans. These include the Chevrolet Venture, Oldsmobile Silhouette, Pontiac Trans Sport later Montana and Opel Sintra. North American minivans were succeeded to GM U-body/GMT201 in 2005.

The GMT 265/267 is a crossover SUV platform based on the GM Sigma platform and used by the Cadillac SRX.
The GMT 325/330 series was a compact truck line including mid-size pickup trucks and SUVs. It debuted in 1982, though it was not given its GMT name until the late-1980s when the new GMT 400 was introduced. The GMT 325/330 was GM's mid-size truck and SUV line, designated by an S (RWD) or T (4WD/AWD).
The GMT 345 is the derivative of this platform as used on the Hummer H3.
GMT 345 Applications:
The GMT 355 is the redesigned S/T compact pickup truck design and the successor to the GMT 325 series. GMT 355s are built in Shreveport, Louisiana and Rayong, Thailand. GMT 355 uses an A-arm independent suspension in front and live axle with leaf springs in the rear. The Atlas straight-4 and straight-5 engines are widely used, starting in 2009, a 5.3L V8 was added. A 4-speed automatic and 5-speed manual transmission are also specified.
The GMT 355 platform was actually a joint-venture with Isuzu, though most of the design was done by Isuzu. Part of the agreement was that GM had to sell it first in the U.S., to be sold legally as an Isuzu. Despite its close numbering to the GMT 360 (also part of the S/T family) series, the two programs share nothing.
GMT 355 Applications:
The GMT 360 debuted in 2002 with the Chevrolet TrailBlazer, GMC Envoy, and Oldsmobile Bravada, as the next generation S/T mid-size SUV's. While it replaced the GMT 330, it shared nothing with the older platform. It used hydroformed frame rails like the larger GMT 800, and was built for GM's Atlas inline engines. The GMT 360 (and the long-wheelbase GMT 370) went on to be one of the most rebadged GM products with six different marques represented.
The 360 uses an independent suspension in front. In the rear, the Ascender and TrailBlazer use a 5-link rear suspension, while the rest have an air suspension. A 4-speed automatic is the only transmission available.
This line is scheduled for replacement during 2009, however, possibly with crossover vehicles based on the Epsilon, Lambda, or Sigma platforms. The GMT 361 replacement program has been cancelled at this point.
Applications:
The GMT 400 and similar GMT 480 is the platform for the 1988-1998 full-size pickup truck platform. The GMT 410, GMT 420, GMT 425, and GMT 430 were used for full-size SUVs from 1991 to 1999. This was the first GMT designation for the C (RWD) and K (4WD/AWD) full-size trucks and SUV's.
GMT 400 frames were built by A.O. Smith Automotive Products, Dana Corporation, and Tower Automotive.

The GMT 510 series were to be based on the GM Lambda platform, and hence are unibody vehicles, rather than vehicles with frames, and are unrelated to the GMT 530/560 series. They would have complemented the GMT 960 series, which are Lambda sport wagons. Due to poor sales of all U-Body vans, this series has been cancelled.
The GMT 530/560 series of trucks are medium-duty commercial trucks, such as the Chevrolet Kodiak and GMC Topkick.
The GMT 600 was used in the full-size Chevrolet Express vans. The currently used version is the GMT 610. A slightly upgraded GMT 620 is in development.
Applications:
The GMT 800 and similar GMT 880 was the basis for the 1999-2006 Chevrolet Silverado full-size pickup truck. The derived GMT 820 and GMT 830 was used in the Suburban, among other full-size SUVs. This is the successor to the GMT 400 series of C/K pickups and SUV's.
Applications:
The GMT 900 debuted at the 2006 North American International Auto Show, as the next generation C/K full-size pickup's and SUV's, and replacements for the GMT 800's. The first GMT 900 vehicle was the Chevrolet Tahoe, which arrived at dealers in January 2006. The GMC Yukon (regular and Denali) and Cadillac Escalade soon followed. Chevrolet Avalanches and Suburbans, GMC Yukon XL's, and Cadillac Escalade ESV and EXT were at dealers July 2006.
Applications:
The GMT 960 series are based on the GM Lambda platform, and hence are unibody vehicles, rather than vehicles with frames, and are unrelated to the GMT 900 series.
