Changing fluid in the Gear box , part or Model S drive train.

I cannot find the actual real Tesla service manual page that states change differential oil at one year?? My SC says they don't do that.
But. A NEW differential should have oil changed . All differential make metal shavings , period.

I believe that’s why they added a filter.

Anyone ever heard of a Company called Pentosin? They have a product called ATF 64. Anyone had any experience with it? The company even released a statement touting it as compatible for Tesla. https://crpautomotive.com/wp-conten...tive-Pentosin-Tesla-EV-Fluids-Award-PR_V2.pdf

History. Back in the day, us gearheads would change rear ends like in 30 minutes to go race. We had built the rear ends ourselves, there was always metal on drain plug. I changed my 2013, it had metal on drain plug.
It takes longer to get tools and pump than drain and refill. Taking belly pan off is a real pain.

Well it took the Clermont FL service center almost FOUR HOURS to change mine. They initially told me it would take less than TWO! I decided to wait, and even told them id be waiting. Never once did they bother to come let me know it was taking longer than expected or give an explanation. On top of that, the tech found the front right axle seal to be leaking. If they had told me as soon as hed found it, id have most likely approved of them replacing it right then and there. Instead they waited until they were done and quoted be 350 bucks to replace it, which im almost positive requires draining the gear fluid AGAIN, which im sure they dont do for free!
