60K Mtce Fluids/Spark Plugs

Taco World!
I'm gathering my fluids and parts for the big 60K service. Where are you guys getting the OEM fluids? I found the Denso iridium spark plugs on Amazon, but no luck with the fluids.

Here's what I need per the owners manual (2019 OR MT):
-Toyota Genuine Manual Transmission Gear Oil GL-3 (GL-4) SAE

$29 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75w-90
-Toyota Genuine Transfer Gear Oil LF SAE 75W
-Toyota Genuine Differential Gear Oil LT 75w-85 GL-5

I have the air filter, oil filter, cabin filter.

Thanks in advance for your advice.

eBay for the transfercase fluid, camelback Toyota for the front/rear diff fluid. Bought most of the maintenance items and parts from camelback Toyota.

 

I'd get plugs from the dealer or at least anywhere else besides Amazon where I don't truly trust that I know what I'm getting.

90919-01263 for the spark plugs.

You won't find the manual transmission fluid sold anywhere, so settle for something else on that one. Ravenol, Redline, Driven, all work well.

The others, just shop around at dealers until you find the price you like. Sparksparts with the chloekuo 5% discount is usually decently competitive. Nothing wrong with OEM fluids but you don't have to stick to them either. I know it's blasphemy but my transfer case shifts to 4HI from 2WD at speed more smoothly on XXW-90 GL4 than it did with the stock stuff, so that's what I go with these days. Some in extreme cold like Canada don’t have the same experience so YMMV.

 

The only thing I bought that was OEM (aside from the gaskets I guess) when I did the fluid swaps at 30k was the Transfer Case Fluid. I did AMSOIL Severe Gear for the diffs and AMSOIL MT fluid (GL4) for the manual transmission. Maybe it was placebo but I did feel like the truck shifted better after

 

For the manual transmission I highly recommend Motorcraft XT-M5-QS it meets Toyota specifications and made a nice improvement in shift quality.

Rock Auto had the best price.

For the differentials any name brand product meeting specifications is fine, I used Redline as they offer the 75W-85 grade.

The genuine Toyota transfer case fluid is expensive but you only need a quart, search around for the best price. Toyota part # 08885-81080

Spark plugs: Lots of counterfeit parts on AMZ/ePay, I bought mine direct from my local dealer.
