    My 2008 Tacoma turned 67k on the way to the shop for a noise coming from the transmission. The whine started in Feb. I originally thought it was the throw out bearing. After changing that out and the sound was still there, I new I had more severe problems. I serviced the transmission and noticed the oil level was very low and smelled burnt. I took the truck to Toyota of Greenville (SC). Their assessment was "internal bearing failure" and said it would be $5000. I appealed to them and to corporate customer care to cover this under warranty....after exhausting that with much frustration, I took the truck to a reputable transmission service shop. He quickly diagnosed the problem (as I suspected) it was gear whine. The transmission had run low of oil and overheated the gears. He pulled the transmission and found the splines to the transfer case were almost worn through. There was gear oil in the cavity between the transmission and transfer case. He noted that it appeared that an o-ring was missing between the two. I have looked around the forums and I haven't seen anything else like this. Has anyone else seen this?

    Looks like it had water in it at some point.
