Transmission Fluid Level Check
To check the transmission fluid level, refer to AUTOMATIC TRANSAXLE/TRANSMISSION - 6F35 .
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 transaxle malfunction and/or damage.
Low Transmission Fluid Level
A low transmission fluid level could result in poor transaxle engagement, slipping, malfunction and/or damage. This could also indicate a leak in one of the transaxle seals or gaskets.
Transmission Fluid Condition Check
- Check the transmission fluid level. For additional information, refer to «AUTOMATIC TRANSAXLE/TRANSMISSION - 6F35»(ref-494559) .
- Place a drop of transmission fluid on a facial tissue and examine the stain.
- If evidence of solid material is found, the transmission fluid pan should be removed for further inspection.
- If transmission fluid contamination or transaxle failure is confirmed by the sediment in the bottom of the transmission fluid pan, repair the transaxle and clean the transmission fluid cooler tubes and the transmission fluid cooler.
- If the transaxle is to be overhauled or if installing a new transaxle, the transmission fluid cooler must be backflushed. Refer to «AUTOMATIC TRANSAXLE/TRANSMISSION - 6F35»(ref-494559) .
