    I need to change my front and rear differentials and transfer case oil. After much research, I still don't know for sure what I need. I have a 2015 TRD Sport.

    Here is what I have in my Amazon cart:

    Redline 75W-85 GL-5 gear oil for rear diff
    Redline 75W-90 GL-5 gear oil for front diff
    Ravenol 75W MTF-3 for transfer case

    On Tacomaworld I read the transfer case needs Ravenol or the Toyota OEM 75W oil in the transfer case because in 2015 they changed transfer case manufacturers. But the owner's manual says 75W-90. So which one do I need?

    Also, can I use 75W-90 in both differentials?

    I ordered the required fill and drain plug gaskets/washers from Toyota.

    Color matched door handles, Weathertech floor liners, bed mat, Durafit seat covers, tailgate clamp, 2016 TRD Sport 17" wheels with Firestone Destination LE2 tires, Toyota exhaust tip, Toyota/Yakima bike rail mount, Toyota wheel locks, Toyota hitch cover, Redline hood struts, unifilter on air pump.
    I believe the 2016 third gen model is when they changed tcase manufacturer. It uses a specific oil, but in 2015, 75w90 gear oil will be fine. I recently changed all of the gear oils in my 2014 with 75w90 Valvoline and have had zero issues.

    I also have a 2015 sport, for front and rear differential I used Redline 75W85 GL-5. For the transfer case I used Redline Synthetic Gear Oil 75W90 GL-5.
