Blown corvette servo in new trans? The vital need to know stuff first.
02 Silvy with an 06 4L60E. The trans has about 15,000 miles on it and a vette servo.
Today the truck gets up to about 4,000rpm and as it shifts into 2nd I get a huge metallic "pang" and I lifted off the gas immediately. I coast down the hill and pull into the parking lot and as I'm coasting I'm listening for anything. I hear no metal grinding, the engine is running still.
I get out and look around, still seeing and hearing nothing. Hop back in the truck, put her in go and get nothing. Pop it in third and the truck just shudders.
What I have figured out. I can get the truck going in 1st up to 20mph. Slide it into 2nd, which feels like it's slipping, and get to 25 to go in 3rd. After that, get it up to about 50 and then go into 4th and the truck goes just fine. It will not fully downshift into a passing gear from 4th but instead just revs.
I still have the original trans, which as it turns out, has nothing wrong with it in the first place.
I also have another corvette servo on hand as well.
So what could my problem be? Or should I get my old trans back in the truck and forget about it?
Thanks for the help in advance.
Mike

It would be very unusual to break a servo , I mean anything is possible but its not something I have seen, But its worth a look as easy as it is to get too

well, what if the trans actually didn't have a vette servo? EDIT: is it possible to break a stock servo?
If the band had popped, I wouldn't get 2nd or 4th at all, correct?
P, R, 1 and 3 work normally. 2 and 4 require some persuasion to work.

Sound more like and issue with the band anchor or even the lining coming off which I have seen. Corvette servo is a stock servo in and F body or GTO

I really thank you for helping me along with this. I have lots of beer if you want to come down this weekend and help. 
Do you think it'd be better to put the original trans back in the truck then?
Or is this maybe something that can be fixed without the trans coming out?

That sounds fair to me. I've got a case of german beers from last month when I stopped into Ramstein AB for a few hours. I've also got a fridge in the garage full of beers, for the moment anyway.

You might take some time and drop the pan first. Take a look just behind the pump where the reverse input drum is and also along the side of the case to where you can view the band. You might see if the band lining is coming off or even see a lot of slop due to the band being broken. If this all looks good then take a look at the servo. I have seen one servo break although there also was a hole in the anchor area where the pin applies on the band. Do you know what kind of band was used?

Vince,
the trans came out of an 06 Silverado and the only thing done to it was the vette servo. I had actually called you for advice a few months back when I was trying to figure out what to do with it. Not sure if I ever said thanks for the advice then, but thank you.

Well the Borg bands do break from time to time. It sounds like you know where the problem is. Now what to do with it? Might want to follow the above advise. 
I love German beer as well although I would require a plane ticket to help you drink it and oh yeah fix the trans!

It's a really good thing that I kept the original trans afterall. And to think that last weekend I was so close to getting rid of it.
Now to see of anyone around here has time to lend a hand. I should be able to do it alone but could really use the extra hands.
EDIT: The bands can't be replaced with the trans in the truck, can they?
And on the off topic, I'll see what I can do about the beers for you and performabuilt.

finallt got started after waiting around for anyone to call back to lend a hand. No calls so I'm going it alone. I watched the guy that removed it very closely and his every move. And from pulling transmissions before but that was when I was young and got help from my dad.
The top bolts on the trans are left to be loosened, then drop the trans cross member and that should be about it. I sure hope the ATV/Motorcycle jack helps and I think it will be fairly stable.
So I'm just taking a break to get a PB&J sammich and a glass of water then it's back outside.

Thanks Gilbert.
I got distracted for about an hour or so trying to fix something else. Then I wanted to take a break, walk over to the clubhouse, past the gym to catch a glimpse of any hotties working out (which there are none), grabbed some Whoppers and a Mt Dew and no it's back out to the garage.
Should be done around midnight. I hope.
