ATF Flushing Process

ATF flushing process - 01J, Continuously Variable Transmission (CVT)

Special tools, testers and auxiliary items required





^ Vehicle Diagnosis, Testing and Information System VAS 5051 with Diagnostic cable VAS 5051/5A





^ ATF filler system F/CVT gearbox VAS 5162





^ Triple square socket driver 3357
^ Drip tray
^ Safety glasses

Work procedure
^ Transmission installed.

With normal ATF change, only about 55 to 60% of total ATF in transmission is replaced.

"ATF flush" procedure is necessary when old ATF in transmission must be removed completely.

ATF must always be flushed with following procedures:

^ Changing input shaft

^ Servicing input shaft

In addition, test run must be performed 2 times and afterwards ATF must be changed, as described below.

Only by doing this will ATF in transmission be changed completely.

CAUTION!
If all these steps are not followed completely, transmission components will be damaged.

- After installing transmission: See ATF, filling for ATF flushing process.

CAUTION!
^ After installing the transmission with a new disc pack or input shaft, the Vehicle Diagnosis, Testing and Information System VAS 5051 A must check before the first drive whether or not update programming in the Transmission Control Module (TCM) J217 must be carried out.
^ If update programming is needed but not carried out, transmission components will be damaged.
^ If update programming is not needed but carried out, transmission components will be damaged.

Check whether update programming in the Transmission Control Module (TCM) J217 must be carried out.
^ Vehicle Diagnosis, Testing, and Information System VAS 5051 connected.

- Vehicle-specific access to Vehicle Diagnosis, Testing, and Information System VAS 5051 in "Guided Fault Finding".

- Using Goto button, select "Complaint registration" function in test plan and find following selection:

Text Lines To Select:

- Press "Transfer" text line and select test program "Jerking when accelerating from stop".

Note:
^ Through this process in Vehicle Diagnosis, Testing, and Information System VAS 5051 update programming is only carried out for the Transmission Control Module (TCM) J217 if this is necessary.

- If necessary, carrying out update programming in Transmission Control Module (TCM) J217.

ATF flush

CAUTION!
