Gear oil question????

I want to change the fluids in my newly purchased rig. I know Im ganna use Redline LSD fluid in the rear. But can I use M1 synthetic in the front and Transfercase?? I or ready have some, is the reason I ask...

Also my truck has 60K miles, should I do the Auto Tranny, If so what do you reccomend? Thanks!
Any DIY's would be nice, I cant seem to find one for the front and tranny.

 

I don't think the LSD rear likes synthetic at all. Just what I've heard.

M1 for the rest is fine, not sure about the tranny.

 

Synthetic for the rear LSD is fine.....as long as you have enough friction modifier in it with the oil. The m1 is fine for the front diff and transfer case. Probably need to stick with Toyota w/s tyranny fluid tho.....unless there is something actually compatible with it.

 

ok cool... I will go ahead and do Redline LSD fluid for the rear, and then use M1 or the front.

Is it a good idea to do the tranny at 60K miles, is it neccesary?

 

Who carries RedLine LSD gear oil? does AutoZone or Schucks?

 

you prolly have to buy it from a specialty dealer. Can prolly get it over at their website

 

Amsoil ATL which is a low viscosity is compatible with Toyota ws. It's workn well for me. I did the DIY flush technique posted by mountain lion.
