Will the 2-4 being burned and the 3-4 clutch pack worn out cause a no upshift

If both are worn/burnt that excessively, yes they will. You shpuld have noticed a slip before they finally went, though. Make sure you check to make certain the srvo release check ball (in the case) is seating properly.

Re: What broke in your 4L60E?

I have a 1996 Camaro Z28. The Camaro has a 470 transmission. The transmission went bad. I took it to F-Body in MD. They replaced the transmission. Almost immediately the transmission would free wheel /Disengage when coating! When I asked for help, they requested that I bring the car to them and provide a demonstration, so a better diagnosis could be made. Later the transmission shift into first and stay there. The car was returned to F-Body. They replaced the transmission. The fault was identified as the following (Never drive around in anything but DR. Or else the computer gets confused and will not know how to shift up). Does this sound possible? F-Body did replace the transmission. At this time I do not have any problems; however, I leave the transmission in Overdrive all the time. Does anybody from the transmission world have feedback on this?

the 3rd gear clutches burned up and littered the whole transmission with fragments

Reverse is still fine. I ended up ordering a Performabuilt, so I will be tearing the dead one apart when the weather is better.
The same exact thing happened to me last night coming from a stop, the car would have a hard time going but when it finally moved it was a little hesitant shifting. How much do you think a rebuild would be?

Check out 700r4l60.com
Dana had built me a trans some years ago that held up to all the abuse I through at it and I also learned a lot from him and the site.

What is the reason to use 2 accumulator 1-2 pistons instead of one
