.80 in a 4K tranny

[jdbubb at verizon.net (Dan Bubb)]

As you go down the pinion shaft from 5th to 1st, all the gears get bigger so they're more likely to splash around in any gear lube that might be there.
Fifth is the first gear to be out of contact with lube plus it's segregated from the other gears and doesn't benefit from any gear lube splashed around by the other gears.
I've seen fifth gear so overheated that the teeth eventually busted off, but the other gears were fine as in not overheated (other than the fact that they had a few teeth busted off too from all the 5th gear teeth floating around in the tranny.)

I don't know why the shifter should be more sloppy, probably pay to pull the shift mechanism out and make sure that's OK.
But, as you say if fifth gear looks good and doesn't have a bluish tinge then the other gears are very unlikely to have overheated.
