Yes, Sonnax worked great, i was a little apprehensive since their new valves look different than the stock ones. They have the o-rings on them that will probably help them last forever. My current valves had scuffs on them and looked worse than the new Sonnax. They made it very easy, marking each of the 3 valves with marks so you don't mess it up.

All the parts i used on this transmission, i purchased in multiple quantities so PM me if anyone is interested to do the same project. I could make them in a complete kit so you have everything you need to complete this job.

I have access to WIS and can paste the images of the step by step guide made by Mercedes
