Proper Transmission
Lubrication
Proper lubrication procedures are key to a
good all-around maintenance program. If
the lubricant is not doing its job or if the
lubricant level is ignored, all other
maintenance procedures are not going to
keep the transmission running or assure
long transmission life.
Transmission internal parts are amply
lubricated if these procedures are closely
followed:
1. Maintain lubricant level and inspect
regularly.
2. Follow maintenance intervals (see
What is Preventative Maintenance?
on page 30).
3. Use the correct grade and type of
lubricant, see Lubricant
Specifications on page 40.
4. Buy lubricant from an approved
dealer.
