In a nut shell....
In order to perform a correct flush (Actual MB Procedure):
Remove the fill tube cap.
Remove and replace the pan filter
Fill pan with 5 liters of fluid.
Remove banjo bolt on fluid return (Pax side of transmission, route line to bucket)
Start car, count 3 liters of fluid, shut car off.
Add 3 liters of fluid.
Start car, count 3 liters of fluid, shut car off.
Add 3 liters of fluid.
Start car, count 3 liters of fluid, shut car off.
Re-install Banjo bolt.
Check sump level using dipstick tool (Factory tool), add as required with sump at 80C.
Thats a 100% fluid flush and should be accomplished every 30,000 miles on the 5 speed transmissions.
Anything less and you are just wasting fluid or delaying a worn out transmission valve controller.
I think your
WRITTEN instructions missed the LAST FILL with 3 liters of ATF he does at...
I'm about to go out and do this soon (today) so I'll let you know. I've got a jerry-rigged set of drainage tubing (all salvaged material from a plumbing project!) hooked-up that I had to let sit for 24 hours to allow the
super glue to cure that had to be long enough to run to a collection jug within eye-sight of me sitting in the driver's seat. That's the cost of using leftover (I.E. free) materials!
