Flex FWD V6-3.5L (2010)
2. Remove the transmission fluid level indicator from the transmission fluid filler tube.
3. Place funnel in the transmission fluid filler tube.
4. With the vehicle in NEUTRAL, position it on a hoist. Refer to Vehicle Jacking and Lifting.
5. Remove the transmission fluid cooler return tube (rear fitting) from the fitting on the transaxle case.
6. Connect one end of a hose to the cooler return tube and route other end of the hose up to a point where it can be inserted into the funnel at the
transmission fluid filler tube.
7. Start the engine and run it at idle with the transmission in NEUTRAL position.
8. When transmission fluid flowing from hose is in a steady stream, a liberal amount of transmission fluid should be observed. "Liberal" is described
as about 1L (1 qt) delivered in 30 seconds. If a liberal flow is observed, the test is complete.
9. If the flow is not liberal, stop the engine. Disconnect the hose from the cooler return tube and connect it to the converter outlet tube fitting (front
fitting) on the transaxle case.
10. Repeat Steps 7 and 8. If flow is now approximately 1L (1 qt) in 30 seconds, refer to Transmission Fluid Cooler Backflushing and Cleaning See:
Service and Repair/Procedures/Transmission Fluid Cooler Backflushing and Cleaning. If the flow is still not approximately 1L (1 qt) in 30
seconds, repair the pump and/or the torque converter.
If new transmission fluid cooler tubes need to be installed, refer to Transmission Cooler, A/T.

Check Transmission Fluid Level and Condition
NOTICE: The vehicle should not be driven if the transmission fluid level indicator shows the transmission fluid below the minimum
transmission fluid level mark or internal failure could result.
If the vehicle has been operated for an extended period of time, at highway speeds, in city traffic, in hot weather or while pulling a trailer, the
transmission fluid needs to cool down to obtain an accurate reading.
The transmission fluid level reading on the transmission fluid level indicator will differ depending on operating and ambient temperatures. The correct
reading should be within the normal operating temperature range.
Transmission Fluid Level Check
NOTE: The transmission fluid should be checked at normal operating temperature 82°C-93°C (180°F-200°F) on a level surface. Normal operating
temperature can be reached after approximately 32 km (20 mi) of driving and can be checked using the scan tool.
Under normal circumstances, the transmission fluid level should be checked during normal maintenance. If the transaxle starts to slip, shifts slowly or
shows signs of transmission fluid leaking, the transmission fluid level should be checked.
1. With the transaxle in PARK, the engine at idle, foot pressed on the brake, move the selector lever through each gear and allow engagement of each
gear. Place the selector lever in the PARK position.
2. Wipe the transmission fluid level indicator cap and remove the transmission fluid level indicator.
3. Wipe the transmission fluid level indicator with a clean cloth.
4. Install the transmission fluid level indicator back in the transmission until it is fully seated, then remove the indicator. The transmission fluid level
should be within the normal operating range.
