Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more with the engine off and is used
only as a reference. Let the engine run at idle for five
minutes if outside temperatures are 50°F
(
10°C) or
more. If it's colder than 50°F ( I O O C ) , you
may
have to
idle the engine longer. Should the fluid level be low
during a cold check. you
mrrst
perform a hot check
before adding fluid. This will give
you
a more accurate
reading of the fluid level.
