do the RX 'boxs have a straight cut first gear?

because i my one makes the same sound in first gear that alot of gearboxs make in reverse...normaly due to reverse being a staight cut gear set

bumpty bump

Dunno if they are straight cut or not.. Have wondered the same thing.. Both of my FT4wd 5 speeds have had whiny first gears. Got better with some decent oil in it. still there though.

 

PS.. bumping late at night on the weekends is not likely to get you much help.. Not too many people on here at that time.

my gearbox in my '88 XT does the same, and as far as I know, the first gear IS straight cut, for it to be stronger when offroading...

 

just as useless as the height button for the air susp if you ask me

mine started making the same noise today when i was wheeling through some deep puddles... but it made it through 1st and 2nd. drove another quarter mile of dirt road and it went away. and it started pulling to the right too... sorda more like "tugged" but it also went away once I got off the trail... balljoints??

Heck - my 4 speed's do that while wheeling in low range up steep hills. The oil drains to the rear of the trans, and the straight cut gears whine like that.

 

If your's does that on the flat and level, I would say you need some decent oil as it's not doing it's job well enough. I use redline - they have a formula for older transmissions that helps the syncro's too.
