4l60e no reverse or neutral Hi all. Hope everyone is having a Merry Christmas. I own a 2007 nbss 4.8 Silverado with the 4l60e 2wd. I got my truck stuck and I was pretty rough on it getting it out. I was rocking it back and forth slamming it from reverse to drive. Now I have no reverse, it goes forward in neutral, and it slams into second. I'm thinking it's not the linkage bc if I drive it in neutral it don't shift like it would in drive. In drive it shifts out.
Now on top of this it will not crank like it's not in park. It will not crank in neutral either.
Just trying to get some thoughts on what I should look for when I tear it down, how maybe I could by pass the neutral safety switch just so I could move it, will engaging the starter work etc. I'm thinking some of the discs are welded together, maybe a broken subshell also.
Thanks for replies in advance

I'm still thinking my forward clutches are going to be fused together. My understanding is that in reverse, it would be stationary if they were but mine will roll in reverse just revs. And I'm not sure why it will not crank now. I think I'm just about to pull it and go thru it to see what's up.
Whats the grand prize for guessing the failed parts?
The low roller is broken and the forward sprag is rolled over. Either way if you miss the problem haul it to a professional.
I will 100% guarantee, I'll bet you the cost of a new stage 10 4L79EHD that the clutches are not welded together.
NOW unless you're not telling you did some dumb **** like held it at WOT in gear without the tires moving at all, yea that will fuse clutches together, did you do that?
When's the grand prize being given? You just going to say **** it and put a used one in and turn this one in for a core?

Let’s back off the a-hole throttle a little and ask a very simple question.
What does the fluid look/smell like?

I've seen the forwards welded on a 60e loads of times. It's really not that hard to do. What he is explaining sounds exactly like welded forwards. No reverse (likely because it's engaging the RI and LR clutches and fwd's are welded...so he's not going to be going anywhere.)
Pulls normal in other gears, still has 3/4 (at least that's what I'm assuming he means by "shifts out" aka shifts through gears like it should)
If the Low roller was broken, it wouldn't move forward in D...same goes for the input sprag. If that was busted, he wouldn't have 2nd or 3rd without having the shifter in D2 or D3
forward in neutral...yep sounds like welded forward clutches.
I'll shoot you my address for the check to that level whatever expensive trans.
OP...yank the trans. Share pics of welded forwards. If it's not forwards...send extra pics of whatever it is!

You've seen forwards welded together, anyone ever tell you what they did? I'm guessing no or they forgot or forgot to tell you that part.
Sure the forwards might be welded together, depends on how long it was held in drive with throttle and not spinning tires.
Forward sprags don't always break and let go 100% same with low rollers.
I'm done with the god damn guessing games.
I have my vision of rocking a truck to get it unstuck. It wouldn't fuse a clutch. I guess I take peoples word to be accurate, shame on me.
