When you get around to bigger tires and lower gears, you may notice the
speedo is all whacked out, either too fast or too slow. The corrective
action for this is to replace the gear that you just found out about. When
you scrub up and go in for that operation, take a look at the surroundings,
you will see markings on the gear housing and the tcase that tell you where
to align the housing. Then, while the housing is out, you will see why the
markings are there.

I remember my dealership's service manager telling me the computer had to be
reprogrammed for the speedo change. HA!

Actually most of the things I had to call them for they turned out to be
totally wrong about.

I trust you guys more than them. :)
