[NT55693]

Greetings all.

I've been wanting a CC since childhood. Finally, well into my adult years, and after lord knows how many rounds of push mowing my little over an acre I found a used 2186-48 (13B-288M100) on CL for a decent price. Currently doing a nearly complete restoration.

I've been lurking around forum posts about repair methods, but I am a little fuzzy on a topic: the hydro transmission fluid, and filter.

The OEM spec fluid for the hydro is cost prohibitive.
Several people have used Rotella T6 5W-40 as a replacement.
I want to do this, as well as use that same fluid in the engine.

This is where I get a little confused.

There seems to be an "either/or" with the fluid in the tranny.
If you use T6, then you need to use this filter.
If you use OEM fluid, then you use this filter.
If you use dino oil, then you use this filter (different filter to prevent air lock I think is the reason).

OEM filter spec for my model is CC part# 923-3014.

I ordered a "Stens 120-265" transmission filter off Amazon.

Will this Stens filter work on my hydro when using T6 5W-40?
No air lock is the goal, obviously.

I live in TX so I figured 5W-40 would be appropriate; only residential once a week use; Agreed?
