tranny or diffy

[dmnknightomega6]

Hey Guys

I was running on the eway and suddenly the car just stopped. i thought it was my brakes locking or something.

I tried going reverse and forward to get to an exit and the car ran and eventually locked.

Is this the tranny dead? or is it the diffy?

i checked the tranny fluid and it was smelling burnt.

and this happened suddenly.... im at a loss on how. only thing i changed was tire pressure. its been getting cooler in chicago...
