Was on a 5 minute drive home (about a mile) from an appointment and I came to a stop to turn into my neighborhood. Once traffic passed I proceeded to turn and the transmission caught for a second, slipped, and then caught again. It made a loud grinding noise while it was slipping. I came to a stop and put it in neutral and started over. 1st gear same thing, 2nd gear same thing. I was able to get it back to my driveway, but I think it was making a gear whine type noise while I was driving for that 1/4 mi...it was hard to tell. If I was hard on the gas, it would definitely slip again. Neighbor flagged me down in my driveway so I stopped there too. Once I was done talking to him I pulled it into the garage and the same thing happened.
Car has 116k miles on it, I'm the original owner. Gearbox fluid was swapped out 7500 miles ago and probably 25k before that. Car is stock except for a Forge WGA I installed in 2012 when the stock one failed. I believe it's making about stock boost levels, but I don't have a gauge so I'm going solely off feel. If anything maybe I'm running 1-2 psi over stock, but it was hard to tell since I was driving with a blown WGA for 6 mo or so prior.
I was originally thinking clutch, but searching a little here, I'm thinking it could be the LSD instead?? I did not notice any smell nor was I being hard on the car when it failed.
Edit: I'll add that I didn't notice anything off prior to this incident. It came out of nowhere. I did not detect any clutch slippage prior to this event like I had felt in previous cars I owned when the clutch went out. This combined with reading some on here is what has me thinking its the LSD.
