Understanding and diagnosing today’s domestic all-wheel drive systems can be quite intimidating. They’re designed to operate in conjunction with many of today’s on-board systems, such as the engine performance system, the transmission control system, and the antilock brake system, which may also include the vehicle ride and stability control systems.

Today’s domestic all-wheel drive (AWD) systems are designed to operate in conjunction with many of today’s vehicles’ on-board systems, such as the engine performance system; transmission control system; antilock brake system, which may also include the vehicle ride and stability control systems; and other systems throughout the vehicle.
In this article, we’ll look at the different types...
In this issue of Keep Those Trannys Rolling, we’re going to look at the 2015 Honda CRV all-wheel drive systems and what it takes to keep them rolling down the road.
The 2015 Honda CRV is equipped with a 2.4L engine, a continuously variable transmission (CVT), a power transfer unit, and either a dual pump system (DPS 4WD), rear differential assembly, or an electronically controlled coupler sys...
In previous issues of Keep Those Trannys Rolling, we looked at the Magna Performance MP3010 transfer case control system and the diagnostic routines needed to keep this four-wheel drive system rolling down the road.
In this issue, we’re going to look inside the transfer case, to see how to disassemble, repair, and reassemble it.

The Magna Performance MP3010 transfer case is a si...
Last time, we looked at Magna Powertrain’s MP3010 transfer case system and what it takes to control its four wheel drive system. In this issue, we’re going to look at the diagnostic routines that help keep this four wheel drive system rolling down the road.
Transfer Case Shift Control Module (TCSCM)
The MP 3010 transfer case system is controlled by the transfer case shift control module (TCS...
The Magna Powertrain model 3010 (MP 3010) transfer case (figure 1) has been the heart of GM’s four-wheel drive truck line since it was introduced in 2011 to replace the New Venture Gear transfer case system.
The MP 3010 transfer case is an electronically controlled, one-speed automatic, active transfer case, which provides three modes of operation: Auto 4WD, 4HI, and 2HI.

Hyundai/Kia Motor Company introduced its first, internally designed-and-manufactured A6 six-speed automatic transmission in 2009. Designing and manufacturing this new transmission was an enormous undertaking for them, with more than 150 engineers spending nearly four years to bring it to market.
With over 300 patents and over 600 individual parts, the transmission’s compact design is on its w...
In this issue, we’re going to look at Ford’s Hill Descent Control system, found on the new 2017 Ford F150 SVT Raptor. Ford has been using Hill Descent Control or HDC on the F150 Raptor, SVT, FX4, XLT, Lariat, and King Ranch models since year model 2013, but most of us aren’t aware of how the system operates.
WHAT IS HILL DESCENT CONTROL?
Hill Descent Control or HDC was originally designed ...
In this issue, we’re going to look at what the future holds for the automatic transmission industry.
Fuel Economy Drive the Industry
Since the introduction of the Corporate Average Fuel Economy (CAFE) standards in 1975, automakers have been at odds with the U.S. Department of Transportation (DOT) and the Environmental Protection Agency (EPA) to improve the gas mileage in cars and light trucks ...
In this issue, we’re going to look at a 2007 GMC K2500 equipped with a 6L90E that had no line rise after being rebuilt. But first we’re going to take a brief look at what makes the 6L80/90E transmission tick.
Getting to Know the 6L80/90E
The General Motors 6L80E and 6L90E 6-speed transmissions were introduced in the late 2005 General Motors truck line as a successor to the 4L60E and 4L80E....
In this issue of Keep Those Trannys Rolling, we’re going to look at one of the most common problems plaguing Allison’s LCT transmission group: inhibited gear ranges or shifts.
These conditions are usually a result of the Transmission Control Module (TCM) receiving incorrect inputs from onboard sensors.
The TCM monitors inputs from several onboard systems to operate the transmission properly....
