We've got transmission noises!
My truck found out I was trying to save up for some SAS goodness and decided to throw
a wrench in my plans :/ Sounds like a countershaft bearing issue to me.  

In 1-3 and 5th (everything but 4th) I hear a constant whine type noise. It reminds me of what straight cut gears/a super charger would sound like if the volume was set to 1 :p This whine is only audible
while the vehicle is "under load" clutch pressed in, giving any percentage of throttle. No noise with my foot off the gas. I imagine a bearing is going out? just based on everything other than my direct drive causing noise. counter shaft bearing?

both fluid levels of the transmission/transfer case are fine,
and I perform changes at the FSM suggested intervals.

well it was rebuilt and stamped by marlin crawler at some point before I bought it, so i contacted them with the whole background story.. see what they suggest. I know I can rebuild it, and have access to all the Toyota pullers... It's just a matter of how long i can go like this, how long my truck will be down, most cost effective action. This thing drives me 50 miles a day 5days a week so I need it back in action. for now im going to keep using it, if its the bearing, I imagine all it will do is get noiser... not much else can get damaged... I hope.

That would make me just slightly passive aggressive :p

It's true though, luckily I have tools and knowledge at my disposal.  
I just need some time and experience to really make it a fun ordeal

heres a vid to help show the sound... 5th gear you can hear it the best. but if you really listen you here the whine quietly behind the exhaust noise 1,2 and 3rd gear.

picking up a trans jack today!

just cleaned the LCE K&N intake today.. interested to see how my mpg will be. Before I cleaned it driving 65mph all highway i managed 21mpg...

I still need to contact Marlin Crawler and find out how interested they are in helping me with my HD trans they built... I don't have a puller so it seems like ill be whipping out my wallet to tear it apart.

Let the festivities begin.

I've got the exhaust and drive shafts out of the way.. clutch slave disconnected. Disconnected starter, and draining the fluids, next up... Cross member!

Painless so far.

Haha ya that was a fun couple of days.

Well got the trans out a few hours ago.. fun stuff.
