I have a 79 series landcruiser, was cruisin down highway in top gear, when all of a sudden i heard a high pitch zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz noise from gearbox.
put it in 4th till i got to mechanic shop. stripped it down and found the thrust washer in fith broke in half! lucky no damage to gears.
thing is i havent towed anything in weeks and ute was empty on a straight stretch of road when it let go.
Every one says it happens because of towing heavy loads on long trips.In my case i wasnt towing anything.toyota say there is no fix up solution but to replace part and hope for the best. now that is crap i must say, im somewhat anoyed that a $33 dollar washer can cause such expensive repair that it could happen again in 700 klms after replacement so they told me.

The only 79 series we had a gearbox problem with, was a 2000 model. Ended up with only syncro on 3rd, and no speedo, all repaired under warranty.

Rang the dealer in the Isa, "how's that toyota gearbox going?"
"Which one, we've got 3 in here now"

We only use 5th gear @ over 80 clicks, so there's no stress on this part of geartrain. Been working so far.

Be a pain in the bum alright, spending all that loot, for a "cheap" washer.

Maybe they need to go back to the old 45 & 75 series, where you could pull a plate out of the floor, and work on top of the 'box from there. Certainly save on some labour costs.

Seen it all, Done it all.
Can't remember most of it.

Have a look at the owners manual and see what it says about driving in 5th. Mine is an older one, 1995 75 series, and I think it said something like only use 5th when travelling over 100 kph.

Yours might say something similar? If it does it might mean a change in driving habit so that 5th is not used in low (below 100) speeds.
