FJ40 grinds gears when shifting into 1st or reverse

Momentary kill switch can aid shifting.

who uses the clutch to shift?

So, I should throttle-blip a H42-4-speed, tcase, when going from 4-high to 4-low? Is this different in some way?

I'd bet that a winter-cold gear box with synchros, downshifting does better with throttle-blip? The oil is too slippery for synchros, when it is at colder/greater-visocosity?

And, in a similar sentiment, some folks warm their gear-oil up with the transfercase in neutral, the gearbox in 4th, iirc. and, of course, the e-brake is on.

So, even for us 4-speed H42 drivers, at a stop-light turned green, we can put less stress on the first-gear-synchro by shifting from neutral into a taller gear, like 4th, and then, while still holding the clutch peda downl, shift into first? (Because the clutch-disk is still spinning at 600 rpm in neutral, and that is closer-rpm-matched to a stationary fourth gear, than it is matched to first?)

Shifting the transfer case on the fly you have change gears in the transmission first.
If in 1st HR then you have to shift to 3rd before shifting to LR. 2nd HR then you have to shift to 4th before shifting to LR. The the reverse to go from LR to HR.

In the winter once it would idle when I let out the clutch I put the transfer case in N and put the transmission in 1st. I don't think it really matters what gear the transmission is in.

When I came to a stop I just put the transmission in 1st and was read to start again.

If my hubs are turned in I can go in/out of 2H to 4H with just a tap of the gas. To go 4H to 4L or back I need to stop.

I put a lot of miles on my 4-speed without using the clutch. Once the RPMs are right it shifted great going up or down.

Same.
