Ok, posted here cause there is a lot of knowledge here and I dont know of any other good sites to get advice for my truck. Please help guys:

Ok, truck is '96 Z71 ext. cab 1500. 5.7 vortec, auto trans, ~70,000 miles everything original.

So, today on my way back home, just after getting off the freeway and accelerating... I get a real nasty loud grinding noise. What the hell? Let off the gas, goes away, back on the gas...grinding. #$&* Roll the windows down, turn the radio off. I hit a red light. When I start to go again there is nothing. I let off the gas, coast.... hit the gas again....GRIND. yadda yadda, it does this intermittenly for 3 more minutes until I get home. On the way home I tried putting it in neutral and reving it, everything normal there...so its only when its in gear. It did it in Drive, it did it in 3rd, and in my parking lot it did it a little in 1st as well, so it wasnt any gear in specific.

This happened just suddenly today for the first time ever. The drive train is all original. Is my trans dying? If so....this sucks, I aint got money for this $%&*.

Thanks,
Tim
