    Howdy gents,
    I'll be changing the manual Transmission oil; 2010 AC Preunner 2.7L 5Spd, 16k miles & it shifts great, but I want to drain any possible metal bits in case the previous owner shifted poorly, for peace of mind, etc.

    It seems routine: fill plug(pass. side, top right?) & drain plug torque are both 27' lbs, 2.3-2.7 quarts till it seeps out the fill hole...but should I use Toyota 75-90W dino factory trans oil, Redline Mt90 GL4, or Amsoil?? I'm in CA, 50-80 degrees year round, minimal cold weather running.

    I've read Amsoil & Redline both make the 5spds shift great initially, but they'll shift less smoothly over time...so is factory Toyota trans oil best?

    Does anyone have actual 1st-hand experience using redline/amsoil &/or Dino oil & how were your results? Thanks!

    2010 Access Cab 2.7L SR5 5spd, 4x4
    5100 set to .85 w/ rear TSB, 2012 Rear-view Mirror, Grillecraft, Team Trails FJ Wheels, TPMS canister, Rear headrest delete, Rear console delete, Valley Hitch, Frame undercoat, $2.99 Tailgate hose clamp lock, Avid light bar, 4x4 lighted switch ala Biceman.
    Any 75w-90 should be fine. I just noticed your in CA so you don't have to worry about sub zero cold shifting issues. I used MT90 which is a GL4 oil that tends to be gentle on the brass synchros in this transmission, but it's not that important they just happen to mention it.

    Edit: get one of those cheap hand pumps from auto store it makes change much easier

    When I had my 2.7 4x4 I changed the gear oil 3-4 times before I sold it with 102k a few months back. I used regular 75W90 GL5 dino oil in gallon jugs from the local parts store. The manual states that either GL4 or GL5 can be used in the transmission or transfer case. Axles need GL5. I used the same thing in all of them. Mine never liked to go into 1st gear unless I was at a dead stop though. Even when brand new in the summer it wouldn't like to do it.
