‘When I Says Woe, I Means Daewoo’

A 1999 Daewoo Leganza with a 50-40LE transmission came into the shop with the driver complaining that the vehicle had no power. It was immediately discovered that the transmission was in a fourth-gear limp mode. The next step was to retrieve codes.

A Guide to the NV 246 Transfer Case

This transfer case is one of the so-called “automatic transfer cases,” or “active transfer cases.” This description results from the fact that the 246 has an “automatic 4WD function,” a 2WD position, a 4WD High function, neutral and 4WD Low position. Driving the vehicle in 2WD has all torque flowing through the transfer case to the rear driveshaft, and the vehicle operates just like a 2WD vehicle.

VW Controller Concerns

A 1999 VW Passat came to our shop. The customer said the car did not feel right sometimes. He left the vehicle for us to check out. Upon going on a road test, we noticed the Check Engine light on, wrong-gear starts and gear-shift indicator lights not functioning properly.

The Best of Intentions

How many of you have said, “Yeah, I’ve got to get out and do some outside sales”? You generally tend to say that when business is slow. You may have every intention of actually doing it, but then life gets in the way. The shop gets busy again, the manager doesn’t come in or a technician quits. Any one of these or 62 other possible problems will keep you from doing outside sales. In fact, pretty much any excuse you can think of will keep you from getting out there, because in most cases if you were being honest, you just don’t want to.
