I've seen that process that you describe done in videos, but it would still require gallons of CVT fluid that would be wasted. It could easily cost hundreds just in the fluid. Remember, I have a replacement transmission if my filter experiment trashes the contaminated one. I'd rather sell the good one, but I consider it worth the risk to experiment with the original and just replace it if all goes wrong.Haven't looked at the Trek's setup, but can you put the suction end in a bucket of clean and the pressure end into an empty bucket and just run it?
I'd want to drop the pan myself.
The filter that I have settled on would be a hydraulic fluid filter that has a bypass and filters to 10 micron. I hope that would be small enough, without knowing for sure.If there's still mud in the trans and lines, make sure the filter capacity is high enough. Don' know if there is any bypass as a safety.
When I drove in North America, I thought every thing would be exactly opposite. What surprised me was the clutch, brake accelerator configuration was still the same. Everything else was just weird. 🐨I'm an expat and still wonder why they drive on the wrong side of the road here...
