NOTE :
Checking the automatic transaxle fluid quality and fluid level is the most basic check of the automatic transaxle. The
fluid check is also an important inspection to determine if the transaxle will need to be disassembled.
CAUTION:
The burnt scent of ATF fluid indicates that the transaxle fluid is contaminated. The tiny particles in
the fluid pan indicate that the transaxle is worn and it will be necessary to overhaul the transaxle.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
