drive with it off, and be careful working on the
engine with the air cleaner/filter off.

Transmission Fluid
It is usually not necessary to check the transmission fluid
level. The only reason for fluid loss is a transmission leak
or overheating the transmission. If you suspect a small
leak, then use the following checking procedures to check
the fluid level. However, if there is a large leak, then it
may be necessary to have the vehicle towed to a dealer/
retailer service department and have it repaired before
driving the vehicle further.
