LC200 Front & Rear Diff / TC Fluid Change / Transmission Drain and Fill / Coolant

[aLwAyS4SaLe]

I am looking for do my 100k maintenance; therefore I will be doing the fluid changes etc. I am also looking to replace the fill/drain plugs or really just have some handy when I am doing the procedure since sometimes rust and seizing seems pretty common. I was looking @ OEM Parts numbers and everything seems very confusing since nothing really marked as drain or fill and impossible to locate in the Parts Diagrams. I was able to come across cruiser path.com and they sell these kits, i was wondering if these are recommended. I was able to locate these OEM part#s; please let me know what you guys think.

Questions:
Has anyone Used these?
Are these recommended over OEM

Transmission Drain/Fill Plug (1): Toyota Genuine #90341-10011
Transmission Gasket (2): Toyota Genuine #35178-30010
Transmission O Ring (1): Toyota Genuine #90301-15004

Also, I understand that there have been numerous threads that I have looked and everything seems a little inconsistent. First, the automatic drain and fill. Some people seem to have 3 - 5 quarts drained, but according to ALL DATA (Mechanics SOftware), it states only 1.4qts. I think I will just purchase 5qts unless someone else has any suggestions. I will not be draining the whole transmission completely so I don't think the recommended 15 its is necessary

Part #s: Toyota Genuine #00289-ATFWS (5qts)

Coolant Flush:
I saw that someone people stated that it required about 16.7L (about 5 Gallons) were used. I just wanted to check with everyones general consensus.
Part#s: Toyota Genuine #00272-SLLC2 (5 Gallon)

Thank you in advance for everyone taking their time to entertain my questions.

Here is what’s in my box, the T-case may have an updated part number as I have both the one pictured and a bag with 90430-18008…. Maybe someone can verify that one for me.

As for the drain plugs. This is what’s in my order spreadsheet and I use these so they should be fine for you, these washer #’s should match that first pic. I will say that I prefer the front diff fill plugs from Kaon but the OEM one is fine if you follow torque specs and hammer slightly on it before removal. That copper washer can be tricky.

If you’re doing your tranny I’d recommend buying a couple extra overflow pipes, they are plastic and easily stripped along with a couple drain plugs so you can have one ready for the last task of checking the level. This will allow you to remove the drain plug with old gasket and grab the new one with new gasket to replace it easily. This is much easier than watching for the correct dripping rate while replacing the gasket.

You want the WS tranny fluid and I don’t recall the exact amount but buy more than you think you need, you should be safe with 5 or 6 unless you’re going multiple rounds to really clean it out.

Coolant is 5 gallons for the entire system and that’s including draining the block. Radiator only you should be ok with 2 gallons I think…. When I did mine I wanna say it was 1.75ish gallons but definitely check me on that before you end up short and have to pull a Red Dawn and pee in that thing.
