Thanks for the advice so far guys. I will try a Borescope first. Believe me this is embarrassing to post lol.. I’ve never done anything close to as stupid as this. The on-ramp is a slight right turn which is the only reason I can think of myself yanking it toward second. ******* stupid and I am sick over it. Worst case I do have another ls1 ready to drop in haha
The slight right is exactly why you did it, you were pulling on the shifter to hold your body. It took me a while to figure out how I did this twice on one car, and after a long time of thinking I realized I was in a right hand curve on the highway banging gears, had never done it in any other car and I have driven at least 100 standard shift cars really hard so I was kinda messed up by it lol until I figured out what the deal was. Both times I did it I was going around a right hand curve. It wasn't even my car lol. I pulled the head and put valves in it both times, because it idled rough immediately after the money shift. Two weeks after I did it the second time, the owner of the car did the exact same thing and I had to pull the head again.
Anyway, if it's hurt you should know, but it doesn't hurt to take a look.
Don't feel too bad, I used to have a friend that everything was handed to him and he couldn't drive for ****, he money shifted from 3rd to second 3 times in a row trying to race another car on the highway one night, that was a LS1 T/A, it didn't seem to hurt anything, somehow.

My first ever dragstrip pass in 2001, 3 months after buying it new, I went from 2nd to 1st locked up the rear and ran a 15.7 @ coasting and was sure I blew up my car right in front of the crowd. Went home with a 13.7 that day but raced it almost monthly for the next few years and when I swapped heads in '04/'05 had no eyebrows nor bent pushrods. Years later at least once maybe twice did the 3-2 on the highway, suffered no consequences. Sometimes you get lucky.
