Just hit the 60k mark time to do another fluid exchange.

I'm not a OEM fluid person when out of warranty. Prices alone made me steer clear of that. When i did my fluids at 35k i had to use OEM to maintain warranty. Now i'm done to the doors are open. I used mobil for the front and rear diffs last time. This time around its either Mobil or Redline 75w90. T-case wants Matic D and AT wants Matic J in the manual but now matic-S. I'm looking at Amsoil/redline both are $10 a qt options VS Castrol import ATF/ Vavoline MAXLIFE ATF which are $5 ish a qt. All state meets matic D, J, K.

WHat have you guys been using?
 
Mobil1 Synthetic Gear Lubricant 75W-90 for the front & rear differential. Mobil1 Synthetic ATF for the transfer case.
 
The filter in our trans is permanent and don't really need to change on maintenance basis. I did a few Transgo Shift Kit install into the valve body with about 100k miles and I don't see any reason for change the filter. If you want to change the filter you have to take the valve body out of the trans to change it since there are couple bolts that fasten through the valve body and they needs to access on the top side of the valve body in order to take the filter out. Take a look at the pic #6 for pic of the bottom side of the filter.

i use redline for the diff, d4 for the tranny and t/c, 0w 40 for the engine and also redline for power sreering...the best for a supercharged fx35
 
I don't see the need to change the filter, it's just a mesh screen on the top of the valve body as Andy said. Mine was perfect when I took my VB out at 50k, no debris at all. It's not like a paper oil filter. And I use Mobil 1 synthetic ATF; meets the same standards as Matic J and S. No issues so far.
