Transmission Fluid Level and Condition Check
|
|
Note
|
|
The following operation includes 2 procedures:
|
|
1.
|
Prefill transmission oil with the engine off after repair work on the transmission, removal and installation/exchange of transmission or axle shafts. After prefilling with the engine off, the transmission oil level must be checked with the engine running.
|
|
2.
|
Check transmission fluid level and correct with engine running.
|
|
1.
|
|
Note
|
|
The fluid level must only be checked in conjunction with the fluid temperature, see diagnostic tool, after performing work or after a loss of fluid and must be corrected if necessary. Ensure that only the correct transmission fluid for AF40 is used for topping up.
|
Test conditions:
|
|
|
•
|
Vehicle must be on a flat surface.
|

|
Note
|
|
If the transmission fluid is only checked, proceed with step 13.
|
|
Note
|
|
The rising tube (3) may not be unscrewed to check the oil level. With the fluid check bolt unscrewed, oil flows out of the rising tube to the oil level (6) on the upper edge of the riser tube.
|
|
The rising tube must only be unscrewed in order to drain the transmission (1). In this case, the seal (2) on the rising tube must be replaced.
|
Prefill transmission fluid when changing transmission and after repair work - engine off. Place collecting pan underneath.
