The billet covers are almost 1/4 inch thicker in the clutch surface area than the OE cover as shown in figure 3. The best way to resolve this problem is to replace the OE covers with a steel billet cover from the aftermarket parts distributors. This problem will even be worse if the cover is machined flat by removing an already thin cover. ![]() When using a dial indicator and rotating the cover each pad area goes back to. This is evident on the few covers that have not been destroyed by the metal to metal contact.įigure 2 shows an OE cover mounted on a flat surface of a converter balancer and the pads marked 1, 2, 3. This causes the clutch surface to no longer be flat, resulting in a leak between the piston and cover during lock-up. Since the cover has the large mounting pads welded to it, it resists shrinking in the pad areas, but shrinks between the pads. When a converter is welded together, it has a tendency to shrink during the cool down process. The OE cover on this converter has three large mounting pads welded to the cover to prevent cover cracking and flexing under load. One other problem with this converter is the design of the front cover that the lock-up piston clamps to during lock-up. There is the broken or leaking rivets that hold the damper assembly to the piston, and the worn valves in the valve body and pump causing the converter clutch to slip. Several of these problems have already been discussed in previous issues of GEARS. Most of these problems have been related to the converter clutch lining wearing away until the clutch is metal to metal on the cover of the converter (Figure 1), causing metal contamination through out the transmission and cooler system. There have been problems with the converter, along with problems in the transmission causing problems in the converter. The 6L80/90 converters have had numerous problems since they came out in the mid 2000’s. ![]()
