M7060 Maintance

[Fezzik]

I'm about to install a creeper gear in my m7060. Its a 2017 m7060 12 speed soon to be 18 speed.
In order to install the creeper gear the hyd fluid needs to be drained out. Thats 15 gallons. I only have 330 hours on the tractor.
The Hyd oil has never been changed. Some was added when a line leaked but it still looks clear. Maintenance schedule says 1000 hrs for the hyd fluid. 500 for the filter. I've seen people change the filter without changing the hyd fluid using a vac. But I have to drain. Would you just replace all 15 gallons of the SUDT2 or try to save it for another 700 hours of use?

Also, its last oil change was in May of 2020 and I'm starting to think waiting to the 500 is too long. I'm in central WI and was thinking of switching to 10w30. I dont use it much in the cold but I'll be snowblowing. Hence the creeper gear install. Should i go ahead and change or wait till the 500?
TIA!

If it were mine, given the age of the fluids, I would op for a complete fluid and filter change.
If you reuse the fluid, at least run it through a really good filter.

I had the creep speed kit installed in my M6060 about 2-1/2 years ago. It wasn't cheap at $1,184 but well worth the cost.

I agree with @North Idaho Wolfman re change the engine oil, transmission oil and both filters. But at a minimum I would change the engine oil and filter since that's cheap insurance, and reuse the transmission fluid after straining it, as was suggested. Interestingly, my MX has a 400 hour transmission oil change interval compared to 1,000 hours for the M6060/7060. The oil in the M has an easier life.

No doubt this is reflective of HST vs GT transmissions. The oil in the HST does work harder.
