whats up with this?
 

today I drove about 100 miles in my truck and 2.2 miles from home I turned the street corner and gave it gas to proceed and all the truck did was wind up the motor, I thought umm, maybe it slipped out of gear. No it did not slip out of gear. I put it down in low drive and it took me about a block farther. I got out of the truck and checked the tranny fluid, the fluid was a tiny bit below full mark, maybe a quart. a friend of mine drove me to the house to get 2 quarts of tranny fluid. I poured 1 quart in the tranny and it showed full. the truck starts and you can run the automatic shiffter threw the drive line locations and the linkage travels with each shift. the tranny filter had been changed about maybe 600 miles ago and the fluid looks good. i cant smell any burnt oil smell and it dont run out of the tranny. the truck does not roll by pushing it when its in park but all the other gears you can push it all over the place.
what the heck is going on with this tranny?. when I put it in drive andgive it gas the drive shaft does not turn, so I'm sure its something with the tranny.
please help. this is my daily drive and only transpertation I have. and I got to get it back on the road. WHAT DO I DO?

need a little more info on the truck. What type of tranny, 4x4, ect.. If 4x4, I would say that the transfer case is bad.

the tranny is in my 81 chevy 2 wheel drive with a 305 motor, the tranny pan sure looks to me to be a 350 becasue of the shape of the pan. and when i put a new filter in it 6 months ago the 350 filter fit perfect and looked like the one I replaced

a th 350 has a pan that is almost square but one corner of the square is cut off.
If the fluid is red and the linkage is moving through the gears it sounds like the interanl pieces int hetrans may be bad. could also be a bad torque converter. time to swap it out

It's been a while since I've worked on a th350 so I don't remember how the filter is held in. One thing you could check is to see if the filter came loose and fell into the pan. No filter no fluid...

Might be the torque converter... It wouldn't turn the fluid black (probally silver)

I would make sure the filter is still on there, also may be a bad torque convertor.

ya know while I have the truck running (going nowhere) I hear a faint whine noise, simular to a belt drive noise. (no belt drive on this poor girl) and at the time I thought maybe the alt. or maybe the power steering pump. well now in my dreams , could this be singing to me the torque converter????how do ya know if the torque converter went south on me. please if you all have thoughts in your head please send them my way thank you all for all your feedback you all rock
