I just called a GM dealer nearby (Canadian) and they had 88862473 in stock, I didn't ask about 88862472 though.

anyone have any info on this????
the canadian and american part numbers are different;
You were trying to find an american part number in the canadian system.
Your owners manual would have the correct part number.

I posted a couple above your comment;

The Canadian part number does differ from the US part number;
US = 88862472
CND = 88862473

If any mod/admin sees this, it might be worth adding this tidbit tothe first post in this thread - especially since the F35/LNF trans fluid replaces/supercedes the F35/LSJ trans fluid.

I put the 88862473 fluid into my car a couple weeks ago when I replaced my axles and seals, and overall it didn't change from the ~6month old ~8k mile 88862472 fluid that I drained out of the tranny.

I can vouch that RP is not good. I had slight syncho issues before changing to RP and then was immedietly better but after a couple of mo. it got considerably worse. Also developed a leak coming from the input shaft.

Use the factory fill. Best gear oil for our trans.

I've been reading this thread and didn't exactly see an answer to this, I have an 06 SS/SC and I'm replacing the transmission. I have 2 quarts of redline mt85, can that be used in my cars transmission or do I need somethin other than that?

PER OP:

8) IF you feel the need to go aftermarket on the fluid, the ONLY fluid I recommend is - Red-Line 75W-90 NS GL-5 Gear Oil, and I ONLY recommend it for the SS/SC guys. You NEED 75W-90 NS, if you plan on using this fluid, because there is regular 75W-90, which has friction modifiers. It does not matter if you have G85 or not. Like I said earlier, our limited-slip is a sealed unit. No fluid you put in there, will see it.

Just go with the LNF fluid

don't use that stuff.
cough up the money, and buy the correct fluid from GM (iirc the LSJ-F35 fluid has been superceded by the LNF-F35 fluid)

How comes the TC says it's the MU3 when I drive a SC and it's the MU3? Or do they not matter?

MU3 was just a production code. Both are technically an F35 transmission, but the TC version has different drive ratio and different axles, different clutch, etc.

They are interchangeable. With a few minor changes.

I know this old, but there is a typo. On 11. It should say the SS/TC transmission is RPO code MC2 and the SS/SC Transmission RPO code is MU3

I would advise against using GL5 fluid. Yea, it can work but it tends to shorten the life of synchros. Sometimes, GL5 fluid can worsen gear engagement. Nissan has gone through this and I believe Hyundai/Kia. I know my trans in my Xterra is needing serviced. I swapped to Redline MT90 by recommendation, and it actually shifts much better. Yet, the damage is still there. If only you could have seen how sparkly the old fluid was. Sometimes have to drive it like an old truck, hunting for that right gear mesh.

75-90w ns

07 ss/sc exhaust mods k&n cold air intake. Ok I guess I have to ask the dumb question when you say 75-90 NS gear oil what does the ns stand for. I have looked at lucius full synthetic but is says it has an additive package royal purple has additive can I even use synthetic is that what the ns is for

ns means no slip, meaning it doesnt have limited slip diff additives. fluids with limited slip additive cannot be used in a transaxle as it causes the syncros to slip on the gear and causes them to be less effective.

Trans fluid

Thanks for your help. I am having a hell of a time trying to find a fluid I can use at a parta store so I can change the fluid I have 72000 on the car and I dont know if it was ever changed. It had 58000 when I bought it. Oh does the differential fluid ever need changed. I know that the company seems to guaranty their stuff for life. Thanks again for all your help

Differential fluid in the f35 trans is the same as the trans fluid. They aren't separate as it's part of the trans.

so why wont that work? Says the same thing as the GM bottle's, api gl-4

and I just bought a 08 SS/TC last week, changing the fluids and what came out of the trans was red as can be..... I think I am going to go with the amsoil stuff.
I'm late to this but also curious about this? Ive used amsoil galore as well and seems like this meets or exceeds what it should need just like their oil usually does.

Experts like John Powell recommend using ONLY OEM fluid in the F35 transmission. This is the most current part number and bottle shape. A good dealer has this in stock (even mine does and they plain suck on all other fronts)
