    In the past the transmission fluid and filtres hadn't been changed 
except when the transmissions displayed problems (not ****fting correctly, 
jumping in and out of gear). Once I implemented the yearly changes, there 
have been no further issues with any of the transmissions. The down time 
that was experienced in the past was a killer on the schedules. They are 
specialized trucks and one can't rent replacements from Ryder, so they
have 
to be working properly every day, all day long.
