HPL Green Cold Climate 2023 Tundra

[carbinefreak]

I'm rolling up to 60k on my 23 Tundra and I was going to "flush" the trans with new ATF. I'm normally a Redline guy with D6 currently in the transfer case and 75w90 in the diffs but since it's hard to source 4+ gallons of D6 I'm thinking of picking up a 5 gallon pail of HPL Green CC. I live up in the mountains of Colorado so a Cold Climate lube sounds fantastic. Does anyone want to share if they are running HPL in their Toyota 10 Speeds or newish WS transmissions? This trans tends to run hot so I want to put something good in there.

@Astro14 is running it in his Tundra.

Dealer drained and filled with 1 gal of HPL Green CC at 17k on a 2021 RX350. So far so good. Wait till July 4 for the 25% off Promo.

I am - but my Tundra is the older, WS specification, 6 speed. It has the separate oil cooler. So, it is pretty easy on fluid.

The fluid is great.

I would use HPL
but if you want D6
Summit racing has quarts and free shipping.

I use Idemitsu in same transmission without radiator cooler. Shifts like a butter.

That looks closer to WS viscosity wise, the HPL is decently thicker which is why I'm wondering what people think of it.

Idemitsu has exactly same additive package as WS, but much lower pour point. It has potential some esters. I posted VOA of that fluid somewhere. I got it on Rock Auto for $36 for 5qt jug. I take Sequoia to A-Basin when I ski with kids and after being 7-8hrs in sub zero temperatures, still shifts great.
Now, HPL in my opinion is upgrade. It will last longer, there is more safety margin.
Also, Motul Type VI is really food one. I used it in Sienna 6 speed, in -30 temperatures, and performed really smooth.

The trans works when cold when the fluid is much thicker so 5.2 vs 6.3 at operating temp is no big deal.
