Red Line 2nd gear

[Keith88]

Today some dic-k wouldn't was blocking me from merging to the freeway on ramp (thats the short of the story). I was in sport mode and was at a stop sign and floored it. It hit the red line in 1st or 2nd (can't remember) and the basically I lost all engine power/throttle and then it came back after letting off. I feel like it was a rev limited?

Anyway this is the second time this has happened to me and it's annoying that sport mode didn't shift and basically my truck took a s-hit in the middle of trying to pass someone.

Does anyone else experience this or has experienced it?

on my old trans this happened a few times. Trans ended up being replaced after the last time it did it... it ate a gear.
