4l60E and 10 bolt death A little over a year ago I blew my 4l60E See thread here.. https://ls1tech.com/forums/automatic...ml#post9175675 Apparently it took my rearend with it? I have a Performabuilt level II on layaway since I haven't had the cash for a trans. But I've noticed the couple times I have needed to move the car it makes terrible grinding noises. It definitely sounded like I chipped a couple teeth in the rear. So I finally jacked up the car and had my friend powerbrake it and put a load on it. Sure enough the driveshaft spins and the rearend makes terrible grinding noises (I hate being right 
). But I don't understand how the hell I blew the 10 bolt and 4l60E at the same time? I was going WOT around 20MPH and it did the 2-1 and when it was time for the 1-2 I hit the limiter. Sorry for the long confusing post... I'm just dumbfounded!
Thanks, Tim

It's actually common that they both break at the same time. I had the same thing happen to me at the track. Took out the 10 bolt and the tranny at the same time on the launch. I went ahead and swapped in a TH400 and will be getting a 9" (just have another 10 bolt in there now). It sucks, but it happens, sorry that you're part of the club now. lol

I always feared that something was wrong with the rear by the sounds... Just never checked till now

I'll just be on the lookout on here for a cheap 10 bolt for now.
