A Different Differential: the BorgWarner 44-82 Transfer Case

Beginning in the 2003 model year, General Motors introduced a new transfer case into its full-size-truck line. The Tahoe, Suburban, Yukon and Yukon XL all feature the BW 44-82 transfer case (figures 1, 2 and 3), which is a full-time unit.

Trail Tested: The NVG 245 Transfer Case

Jeep is the originator of four-wheel-drive vehicles, and even though the brand has been owned by numerous corporations over the years, it is still the centerpiece of four-wheel activity. The top-of-the-line Jeep model is the Grand Cherokee – or WK series, in Jeep speak.

GM IFS Front Drive Axles

In 1983 General Motors redesigned the front drive axles on its four-wheel-drive S and T trucks. The new design was an independent front suspension (IFS) for better handling and ease of manufacturing and repair. In 1988 GM added IFS front drive axles to its full-size-truck lines (K trucks).

Identifying BorgWarner Transfer Cases

We have assembled here an identification guide for the current-production models of BorgWarner transfer cases, which will include a number of models that are not sold in the United States. Since we now have a global economy and Transmission Digest is read by technicians around the world, it is necessary to try to help our brothers in other countries to identify the complete line of transfer cases.

Solving Common Noise Problems, and Problems with No Solutions

Noise is one of the great mysteries of the transmission world. Noise is subjective, and people rarely can interpret noises in the same manner. Noise travels much faster and farther in solid objects such as the steel of an automobile than it does in air. There is driveline noise, engine noise, suspension noise, exhaust noise and road-generated noise.

Dual-Clutch Transmissions – the Future Is Here Now

The automatic transmission equipped with a torque converter has been the mainstay of conventional drivelines since World War II. A great deal of research, improved designs and advanced transmission technology have brought us excellent five-, six- and seven-speed automatics that perform extremely well. Manual transmissions are still more efficient from the fuel-economy standpoint but depend on the driver’s skill and ability to drive in a fuel-efficient manner. The EPA does not like manual transmissions because they shift at closed throttle. Automatics shift at open throttle and make control of emission levels much easier.

Interrelated Vehicle Systems

With the steady advance of technology, motor vehicles have become safer, more fuel efficient, less polluting and much more complex. This will continue to make very large demands on the people who work at repairing them and must learn how these systems work and how they relate to each other. Failure to do so will be a career-threatening move.

The Fine Points of the BorgWarner 4411 Transfer Case

One of the best-selling vehicles produced by Ford Motor Co. is the Ford Explorer/Mercury Mountaineer SUV. These vehicles started production using the BorgWarner 4405 transfer case and had a huge production run.

Generations of Transfer Cases: The New Venture 244 Gen II

With the introduction of the Dodge Durango to Chrysler’s SUV models came the 244 transfer case. From 2001 to 2003 the 244 transfer case was an evolution of the NV 242, which was a full-time/part-time unit.

Getting to the ‘Core’ of the Problem

Cores and core charges have been part of our industry since the beginning. What is a core? There can be many definitions, but for the purpose of this discussion we will label it as a used or worn/damaged component or assembly being replaced by a remanufactured component or assembly that is identical to the one being replaced.

Tremec’s New 6060 Six-Speed

The T56 six-speed transmission has been around for many years now. Originally designed by BorgWarner for the GM F-bodies (Camaro/Firebird), the design has been refined since Tremec bought the BorgWarner manual-transmission business. The T56 is now the six-speed of choice for the Ford Mustang, Chevrolet C5 and C6 Corvettes, Pontiac GTO, Cadillac CTS-V, Dodge Viper and Sidewinder, and Aston Martin Vanquish.

2008: Will It Be Great, or Will It Be Too Late?

I have always believed that to be successful one must have a positive outlook on life. Whatever you do should be done with passion and excitement, and to the best of your ability. If you don’t enjoy what you are doing, it is time to make a change and get into something new. An old quote says, “If you love what you do, you will never work a day in your life.”
