Belive it or not since I bought my truck in Feb. I had not opened it up to see what it would do until this week. Well, I was taking off yesterday and put the pedal on the floor. My question is this, I was up to approximately 75mph and looked down at my RPM's. I was running like 3300 rpm's and it was in the red. I let off the pedal and it shifted gears and everything was fine. 1. Is this normal and 2. does this engine have a rev limiter on it to keep you from red lining and blowing it up.
