01M 4 Speed Automatic Fluid change Procedure
Here is the step by step on how to change the ATF fluid in the TDI 4 speed 01M Automatic transmission. For the parts lists I included cropped picture links to the ETKA pages relative to the 01M transmission.
NOTE:
-This is not the differential fluid which is independent of the ATF and is a different type of fluid. Please refer to the Bentley manual for the simple instructions on changing and checking this fluid.
-This job relies on ABSOLUTE cleanliness. Some of the pictures do not reflect the cleaning that took place when reinstalling the parts due to reuse of certain picture frames. Above all make sure that no dirt is allowed to get into the transmission housing. The housing and valve controls contain extremely close tolerance electronically controlled servo valves similar to those found inside the TDI injection pump.
