A Disappointing Reality
One recent week, Luis was having a problem with an 01M in a 2002 VW Jetta (see Figure 1). It had a slight bind-up on the 3-4 shift. It didn’t make a harsh shift; it was more like a dragging shift that lasted for about 1 second and then suddenly released when it finally went to fourth. Typically, what we see on the tech lines is more of a 3-4 shift flare rather than a dragging shift. This flared-shift complaint is usually due to either an incorrectly assembled K1 or B2 clutch pack or a leak in the K1 pre-fill pressure circuit causing the clutch to release too soon. However, a dragging shift also could be due to an incorrectly assembled K1 or B2 clutch, or a valve-body problem.
