    Cool T56 Transmission Fluid

    What are y’all using for transmission fluid. Yes, I’m changing the transmission fluid for nationals.

    I’ve been using synthetic power steering fluid since 2001
    Well, not the same fluid but you know what I mean.

    I've been running plain non synthetic pennzoil synchromesh. It's a touch notchy when cold but shifts like butter after the first warmup lap.

    The tremec guy here in TX said for what we do the shear resistance and protection of synchromesh is better than just running dexron iii, and to run the pennzoil (also valvoline, which is just pennzoil in their bottle) synchromesh.

    For a street t56 I would run regular dex III to avoid the notchines/wear from cold shifting.

    Then again I also ran synthetic redline D4 for four seasons and when we took it apart to do the LS conversion everything still looked great, so I have no idea lol.

    My track car has had redline d4 in it almost since new, 15 years. Fluid changed every year.

    C'mon mister oil expert. Pennzoil is the label they stick on Shell lubricants (same guys that make the rotella) sold in the US these days. The exact same stuff gets a shell sticker overseas.

    Pennzoil is nothing but a label brand these days.
