Try the Red Line MT-85, it's a GL-4 fluid and you'll like it.

 

To The Top! Hopefully this can help clear up confusion with the F35 transmission!

 

Bump!

 

so how oftern should we change it? by years, or by miles? what if you never drive your car? i put like 6600 miles in one year and seven months.

 

Post #1 point 10).

Although I believe it is a lifetime fill by GM standards. Nothing about it in the owner's manual.

 

I put 3800 Miles on since July of 2009. Hard Miles. Broke the trans at 2200 and when the dealer fixed it they had no trans oil in stock. Took a few days to get it in.

 

I would go by miles.. I was the second owner of my car, and I bought it with like 57,000 miles on it.. The fluid was never changed, and I got to it around 64,000 miles.. It wasn't horribly burnt, but it definitely needed a change, and I could absolutely tell the difference.

Whether it was the LNF fluid, or the fact that it was just new fluid in general, I'll never know, but it feels way better.

There was also a fair amount of shavings on the plug. This is normal.

 

OP: How much does the LNF fluid run @ the dealership? You said it's okay to run in the LSJ w/LSD transmission right?

 

I think its about $14 bucks a Quart if I remember correctly

 

any info the 2.2?

 

thank you very much for this write up!

 

My dealerahip has both fluids stocked. Lsj mu3 and lnf mu3. They have 8 of each. Just letting u know cost is 13-17 depending on fluid.

 

I'm almost afraid to check...

normally prices of stuff at dealers is about 300% more in Canada than in the good old US of A

 

Absolutely. In fact, I completely recommend it.

Welcome!

You'll want to ask someone else about the F23 trans.. AFAIK, it uses Dexron ATF.

 

cool

 

F23s use Dexron ATF or similar. I recommend Mobil1 ATF or Redline D6 for F23s.

 

THANK YOU so much for making an official thread.

So tired of everyone arguing that "RP ARE BEST BCUZ DEM MAKE GUD OIL"

 

im probably going to go with amsoil synchromesh. but i have lots of experience with it in the past. i like my tranny butter smooth, and thats what it does without causing problems. fixed essentially every issue my last cars tranny had (06 civic si)

 

This isn't a Civic, stick with a GL-4 fluid.

 

Civic are butter so it needs butter to run lmao... and shift smoothly just saying.

 

sub'd

 

-facepalm-

 

LNF Trans oil was $45 a bottle here at my Dealer in Ontario

Im switching to the MT 90 in the Spring

 

Wowowowowowwowowo. F*** that lol... move to the US lol.

 

Red Line MT-85 is a viscosity match for our GM LNF fluid. (GL-4 Castrol SynTrans)
