2019+ Tranmission cooler parts - additional 25% off from the sale

how many qts of trans fluid do I need if adding the cooler and doing a drain and fill?

 

I've seen 2 extra over the 4 you need for the drain and refill.

That said, I used 4.5 quarts on my recent drain and refill. So I ordered just another single quart of ATF to go with my 1.5 or so I have left. I'd personally rather have a quart extra than need to run out and get more.

 

Are any o-rings needed for the Trans T Stat or the trans drain plugs or fill plug?
If so, do you happen to have the part number?

 

Thanks to all for the quick answers and promo code. I just placed 2 orders.
One order with all the parts needed for the trans cooler as well as the brushless Land Cruiser blower, 12 qts of trans fluid, 4 cases oil, and the union and breather for the diff breather relocation.

The 2nd order was under my wife’s account so we could take full advantage of Toyota’s 25% discount and free shipping which included 6 cases of oil, oil and cabin filters and Pcv valves for the Tundra and GX

Total before discounts. $1718.66
Total after discounts $671.31

still need to order the trans cooler and mount and buy the hose to make final connections.
Total should be around $900 all in I’m hoping. I should be stocked with oil and some maintenance items for a few years now.
