I recently changed all my fluids on my 4runner. I have a 5spd and put in mobil 1 75w-90 in both the tranny and t-case. Now it stinks like gear oil bad inside the cab. I can smell it coming from the shifter, its especially bad on the hwy and under a load. I drained and refilled till fluid came out of the fill hole. Anybody experienced this problem? I can't take out a girl smelling like this

 

I'm experiencing the same thing after using the same oil. No idea on how to get rid of the smell.

 

try different fluid?

 

Strong air fresheners and open window?????
