The 11.5 AAM 14-bolt rear differential started replacing the 10.5" 14-bolt in Chevrolet Silverado and GMC Sierra trucks from the 2001 model year onwards. However, the 10.5" 14-bolt axle remains in production today, specifically utilized in GMC Savana and Chevrolet Express vans.
General Motors (GM) is an American car manufacturing company. It manufactures its own automobile transmissions and only purchases from suppliers in individual cases. They may be used in passenger cars and SUVs, or light commercial vehicles such as vans and light trucks.
The HM290 and 5LM60 units have a complicated arrangement of 4 shift rails. The NV3500 has one shift rail. [2] There are two designs for the 5LM60 input shaft and bearings (input shaft and main shaft). The first design 1988–1990 has a ball bearing with a roller bearing behind it. The second design has a much larger single ball bearing.
The 6L 50 (and similar 6L 45) is a 6-speed longitudinally-mounted automatic transmission produced by General Motors.It is very similar in design to the larger GM 6L 80 and 6L 90, and is produced at GM Powertrain plants in Toledo, Ohio; Silao, Guanajuato, Mexico; and by the independent Punch Powerglide company in Strasbourg, France.
First-generation Chevrolet Silverado 2500HD (2001–02 Regular Cab) The GMT800 Silverado/Sierra 1500 and 2500 pickup trucks were released in August 1998 as 1999 models.

A typical 7-speed shifter changes the cable length by either 2.9 mm (Shimano 2:1) or 4.5 mm (SRAM 1:1) for each shift, and any length errors accumulate with the number of shifts. To this end, the housing needs to behave as if it were a solid tube, so it, and its end-pieces have to be compressionless.
The police package (9C1) B-body cars featured a First Gear Block Out (FGBO) Plate on the transmission housing to prevent drivetrain damage. The shift point for first to second gear is about 43 MPH (69 km/h) while second to third gear shift point is about 83 MPH (134 km/h) assuming a 3.08:1 differential and a 5,500 RPM engine speed limit.
A park by wire system engages the parking pawl of a transmission using electrical means, without the traditional mechanical system which involves linkages between the gear shifter and the transmission. Park-by-wire can be considered a part of a shift by wire system, as it shifts the transmission into park mode. [1]
