The tach on my '89 1500 GW has started to read about 1500 RPM too high. On shifts, it goes into the red when I know the motor is not revving at that level. Any ideas how to fix the problem?. Thx, Schweg

It's kind of hard to give you any useful information unless you have some way to measure the actual rpm vs. the indicated rpm. Even with the suspected error that's a pretty high shift point for a 1500, normally up shifts around 2500-3000rpm are commonly used unless you're trying to squeeze maximum performance acceleration. With the torque available from the six cylinder engine upshifts can be done earlier at lower rpms and provide good performance, smoother shifts and longer lived clutches and shift forks.
Is this an intermittent issue? The tach on my '89 occasionally reads about double. Lots of redlining during relatively tame acceleration. Then all of a sudden it will work corerctly for a few days. I suspect a loose connection, but haven't taken the time to check it yet. That may have to be a rainy day project.
