Have a 98 LS400. I can't figure out the washer and drain bolt part number.
I'm assuming they're not reusable right? I'm planning to drain and refill from pan multiple times.

So any help on the part number,

This was confusing

You want numbers 2 and 3 below.

1. P/N 9008034016 (Drawing Item No. 35104A), Transmission Drain Plug (Rear), fits into two places in the the transmission case; one in the front side, one in the rear side.
2. P/N 9034110011 (Drawing Item No. 35106A), Transmission Drain Plug (Front), fits into the pan.
3. P/N 3517830010 (Drawing Item No. 35106B), Gasket, mates with P/N 9034110011.

The side plugs in the case appear to be fluid pressure taps.

When I do multiple drain & refills at one time, I remove the drain plug and temporarily replace it with a Fumoto drain valve (F124N).
You dont have to drive the vehicle around (just shift it through each range) so there's no risk of ground clearance impact. Just replace the valve with the plug after the final drain.

FWIW, here's a dilution calculator image (for the A650E) showing how many drain/refills you need to get x-% "clean" fluid. It's hypothetical but close enough.



Use T-IV or an equivalent ATF. I use Edemitsu TLS (Toy-Lex-Sci).
