Here is whats happening. I was driving on the interstate the other day and I had dropped the speed down to 60mph. Now this is usually a good spot for me to pull like mad to 70mph so I push the pedal to the floor and to my surprise the car goes to 75mph and revs to redline before shifting. The issue is that it seems to only do this every once in a while. My car is basically noly reving to about 6200 max about 90% of the time. Just wondering if anyone has any ideas as to why it sometimes wants to rev all the way to redline and then others it wants to shift at 6200. By the way most times my car shifts at the same point with OD on or off.
