I’ve had twin turbo soarers since 2002 so i’m Pretty familiar with them.
I tried GM Dextron III it’s a good way to kill your trans. Ended up dumping it after a couple of days and spent the money on proper toyota fluid. These transmissions are very sensitive. You might save a bit of money using cheap oil but it will cost you more in the long run when it starts slipping and eventually fails.
As mentioned, i used to run 10w50 and it’s not as good as the 5w40 as it takes longer to build pressure.
I tried platinum plugs as well as others but you’ll find the copper plugs work better. I had smoother idle with platinum but noticeable loss of power.
