Had a 97 Sub, which experienced same problem...2nd and reverse. I saw the broken piece(s), but would need a parts breakout to remember the name of the piece that failed. It's some sort of drumlike part, which housed as I recall a number of the clutch plates. It broke at it's spindle connection hub. I had called around to get estimates which all tended to be broad ranges, except the AAmco guy....based on my symptoms indicated what it was most likely, and he was right on.
 
As soon as my failed (noticed that it didn't shift into 2nd), I was within a couple miles of home and parked it. When he later opened it up and showed me the parts, he indicated he could tell I didn't drive around on it much because there wasn't much other damage. All told as I remember, there were three parts that had damage that needed replacing....the original failed piece, and then two others when a broken off piece got sucked in between two other gears. When the metal chunks break up, if they get in any of the other gears they will ruin those gears.
 
I don't have the receipts anymore as I've since upgraded to a newer model year, but as I recall it your estimate is in the correct price range.
 
I have always done all of the work on our vehicles over the years, including a couple engine jobs and a number of manual transmission clutches, but this is not a job that I had the desire or reasonable comfort factor that I could do. Plus, it's the vehicle we use for long distance family trips, and I didn't want to get stuck somewhere if I didn't do it right. I had the factory service manuals, and it just appeared way too complicated for my liking. I didn't want to take the risk that I did the job, and put it all together and then found out something wasn't right and I'd have to take it apart again to redo something.
 
I was told to stay away from Transmission chains, but my local guy was a real knowledgeable professional, who knew exactly what he was doing. Compared to a couple independent shops, he just sounded more knowledgeable. He obviously had training and experience, which was worth it to pay for. It obviously is a big repair bill to swallow, but given how worthless the car is without a transmission, I don't think you have much choice but to fix it.
 
When it came to warranties, IIRC there is a 90 day warranty, but I could buy an optional extended warranty. I don't remember the cost, but the guy said listen....I don't know your tolerance for futher pain and ability to absorb another repair bill if it happens. But I've checked everything over and your transmission is in great shape now, and I don't see the need for you to buy an extended warranty. I didn't, and he was right. I don't know that you'll find that kind of trustworthy professional elsewhere, "your mileage may vary".
 
All the shops offered to tow the vehicle in "no charge", which you should also do to avoid further damage.
 
Good luck, in whatever you decide to do.

I have a 96 tahoe 2 door 5.7 4x4. Driving down the road today and stopped being in
gear, reset the code, disconected the battery to rest also, checked the drive line, checked to see if the tourq converter was connected. I have no R, no D, 1, ,2, 3.
 
Time for a new transmission or is there something I don't know?

1999 Chevy Tahoe 5.7 4x4.Same thing happend to me today. transmission was not making noise, not slipping and has been shifting flawlessly. Was stopped at stop sign. Stepped on the gas to move forward, rpm went up but no D321 or R. After sitting for a few minutes it would engage again but only for a short time. Fluid is full, no visible leaks, no slippage or audible noise. Had it towed to a transmission shop for inspection. No answer yet.Don't want to get ripped off!! Anybody have any insight on this?

I'm getting a new trans soon $1400.00. shipped. I'd like to hear what they say is wrong with it though. If you need to get a new trans, I know a good place.
I wish these guys would reply!

can you post a URL to the place you get a transmission for 1400?
 
Is it pulled out of another vehicle, a rebuild, or new? What kind of warranty?

Don't currently have a transmission problem, had a 97 burb in the past with one, and had the local transmission shop fix mine.
 
Just keeping track of what the different fix alternatives are, and what they cost.
 
So in your case, you are going to have someone swap out the whole transmission, and it appears you have a friend who has a lift and labor who can help you do that. And then justin will take your old transmission back, rebuild it, and make it available for the next guy.

thanks for the reply to my questions.
 
 So after contacting several shops and getting prices it became clear to me that this has to be a pretty common problem with my trans since all off the trans shops knew exactly what failed when i described it to them. It has a broken sun sprocket which tends to wear and break after excessive abuse or a lot of miles which I have.
 
The differences in prices were varied from over 2000.00 to around 1200.00 with just about every shop adding (give or take a couple hundred bucks). I kept my searches to local shops that took the time to talk to me about it on the phone and avoided the chain store type of operations altogether.
 
So with a bit of knowledge about what it costs for parts for this repair and the care that is needed to do the job correctly I was able to get a reasonable price and a 2 year warranty. I don't have the final price yet since it is currently in the shop but I was told it will definitely not exceed 1400.00 dollars. and that is with a heavier gauge sun sprocket (after market part) and replacement of the planetary gears included in the rebuild. also the transfer case seal will be replaced since these tend to dry up and become brittle which allows trans fluid to leak into the transfer case. This I am told is a VERY common problem and can result in the loss of 2 quarts of trans fluid into the transfer case. And within only a couple years of age of the vehicle.
 
And as for the clunking sound from the drivetrain , apparently GM considers this normal!!!??? This is what I was told by several trans shops and the fix that they use to try and alleviate some of the binding and noise is to improve the finish of the surface on the input shaft going into the transfer case and lubricate it well so as to improve its ability to adjust within the moment of its engagement. sounds a little sloppy from the get go, but hopefully that will help. It is a major annoyance and takes away my confidence in the soundness of the drivetrain. Unacceptable standard of quality if you ask me. I will be listening carefully if I venture into a showroom for a new vehicle.
 
keeping my fingers crossed and my expectations high.
 
I will post again with my impressions of the repair when I get the vehicle back.
