Transmission fluid change: 300 or 600 hrs?

[heberer]

The M6040 Operator's Manual shows two different intervals for changing transmission fluid.

* The Service Interval chart says 600 hours

* The Periodic Service chapter says 300 hours.

What is it? I'll hit 300 hrs. this week.

52 liters, wow! (55 US quarts) I like to do my own work when possible . . . besides finding enough buckets for ~14 gallons of fluid, are there any reasons I might want to have the dealer do this service?

Happy July 4th!

Welcome to OTT Heberer. My WSM says every 400 hours so I would do the 300 hours.

At 300 hours you just change the filter.
At 600 hours you change the filter and fluid.
