FLUID LEVEL AND CONDITION
Transmission Fluid Level Check
To check the transmission fluid level, REFER to: Transmission Fluid Level Check .
High Transmission Fluid Level
A transmission fluid level that is too high may cause the transmission fluid to become aerated due to the churning action of the rotating internal parts. This will cause erratic control pressure, foaming, loss of transmission fluid from the vent tube and possible transmission malfunction and/or damage.
Low Transmission Fluid Level
A low transmission fluid level could result in poor transmission engagement, slipping, malfunction and/or damage. This could also indicate a leak in one of the transmission seals or gaskets.
Transmission Fluid Condition Check
1. Check the transmission fluid level, REFER to: Transmission Fluid Level Check .
