    When would you replace your differential fluid and would you replace it with anything other than Toyota recommended fluid?

    I have a '15 CM 4x4 SR5 TRD that just ticked over 60k. Transmission fluid replaced by the dealer about 10k miles ago for a rough shift from 1-2 gears.

    Always appreciate the advice!

    I did mine at 40k with Mobile 1. I did it at 40 cause I tow a bit, although it looked like new coming out so I could have waited at least another 20k.
