Just recently my 1987 Delta 88 3.8L V6 oldmobile had a transmission
failure.  The engine appears fine so I do not believe that to be the
problem.

No warning or anything and now I have no drive in any gear.

Symptoms:
1.  Fluid smells fine, when off and after checking in park motor running
fluid level shows high.  The times I've checked before problem level was
high when off (expected) and when running level was correct.

2.  After several minutes of driving car loses all drive in any gear.

3.  Sound like a 2 cycle string trimmer from engine compartment seems trans
area but not 100% sure, sound is in all gears.

4.  Car seems to work again for a short time after turned off and allowed
to sit for a few minutes.

I'm trying to get some idea of what might be wrong and what it may take to
fix it either as a DIY or at a shop.

I will admit I did also post this to alt.autos.oldmobile but it is a GM car
and this seems a much more active group.

Thank You
