ShoBoat Posted April 29, 2015 Report Share Posted April 29, 2015 At the beginning of last week I thought I may have an exhaust leak, so I decided to take a good look. While under the car I noticed that the PTU was leaking a bit from the vent. So I took it in and they swapped out the fluid and did the TSB on the vent. What is interesting is that I monitor the PTU temp (mine has liquid cooling) through torque. I started to notice that the temp is effecting much more now. It used to lag way behind the trans temp. I can actually see the temp cool at a light and go up at highway speeds. I am guessing that this was due to the low fluid in the unit. The moral of the story. Check your PTU for leaking. Mine was just in for an oil change about 4 weeks ago and they said nada. The temp gauge has been acting like this since last year, the temp sensor is in the fill hole, I am guessing that if the fluid is down at all it will act like this. So its been down on fluid for a while. Just some food for thought.
