It appears that many who have swapped to higher powered motors, bigger
wheels, and or overloaded their vans with accessories have had to
rebuild their transmissions frequently.  That is becoming more clear
as time goes on.

Be modest about what you do change, and don't change your driving
habits from what you'd normally do given that you are driving a
vanagon. That's the take-home lesson I got based on my readings.
