    Hey, I have a 2008 Tacoma SR5 V6 in a six-speed manual. I have the TRD Sport. I was planning on changing out the differential fluid in the rear, front, and transfer case. I bought some of the Redline 75w-90 for all three on the recommendation of the guys at O'Reilly. Just wondering, will this fluid work for my particular truck or do I need to return it and get something different/with additive? Any help or recommendations would be great!

    Hey thanks. Just saw other threads saying that it might need an additive for the sport but didn't know if that would apply to the manual transmission. Reading the description in the link you sent, it says maybe not the best for a manual? Any concerns? Would you go for something else or just stick with it?

    Redline is a great product, you got good advice, should be good to go as far as oil but remember to replace your crush washers and loosen the fill plugs 1st

    This is what I have in my manual transmission. I wouldn't put the other stuff in there.

    Redline sells differential specific 75W-85 gear oil. It’s a little pricy but worth it.

    The rear diff should be a LSD so you would need additive for that, the front diff and transfer case take regular gear oil, not sure about the standard trans I have an auto.

    The Redline apparently already has friction modifiers added for a limited-slip differential in the 75w-90 so I guess that will work with no additional additive needed. Contacted the dealership just out of curiosity to see what they would say. They recommended 80w-90 in the rear, 75w-90 in the transfer case, and 85w-95 in the front. Also said I didn't need an additive (although this truck should be an LSD so I don't think that is correct).

    I have a 2008 X-Runner, and the Redline has worked just fine for me without any added "friction modifiers." But make sure it's their GL-5 gear oil. Their GL-4 oil is made for manual transmissions, so it doesn't have it. If you buy the wrong one, you just have to buy a tube of LSD additive and squirt that into your diff pumpkin.

    For my X-Runner, Redline recommends:
    4 quarts of 75W90 GL-5 gear oil for the diff, &
    3 quarts of MT-90 75W90 GL-4 for the manual transmission.

    crap!..... I thought I had read on this forum that Redline 75W - 85 GL-5 gear oil was best to put in my 2 wheel drive rear dif that is LSD....... is it a big deal between the 85W vs 90W? I actually will be getting the 75w - 85w GL5 delivered today through Amazon

    Frankly I doubt you'll see any difference between the 85 and 90 weight oil.

    I always go to the Redline website, type in my vehicle specifics, and they give me their recommendation for engine, transmission, and diff oil. (I only use Redline in my transmission and differential.)

    not sure if you changed your fluids yet, but it is significantly easier to access everything if you remove the spare tire first, unless you're doing it on a lift.

    Thanks for that........ I finished it up about an hour ago .... I didnt remove spare but should have .... it prob would have been better if I bought the 90W since I am in the warmer climate here in Florida but I did just find that Toyota spec for my truck is the 85W so until next change time the 85W will be fine
