Thanks for the posts.  Unfortunately the transmission, which I just
spent over $2000 to have rebuilt, has completely died again.  It won't
budge an inch.  Assuming I don't take a sledgehammer to it in the next
few days, I'll try your recommendations.  Many thanks.

I read all your previous comments and did not detect if you had the computer codes
pulled? Any Autozone will do it for free, worst case a small shop with an OBD-I reader
would charge 50-75 bucks and get them for you.

my other suggestion would be to purchase from Napa or Autozone (avoid other parts
dealers) the most expensive Idle Air Control sensor and Throttle Position Sensor, cost
for both parts would be around 100, in total. Can't hurt either way.

finally, if you read my note and the link posted, you may have a faulty ground and
could use any generic advise to install a ground wire between transmission and engine
or transmission and body (or do both, no harm either way)

I'm suspecting the problem now with this POS is the torque converter.
I've just paid 2K for a new transmission, replaced the egr valve,
plugs, pcv valve, fuel pressure regulator, and all filters.  It still
feels like the brakes on when I drive, especially uphill and a
whistling vacuum of air is heard when I first crank it up.  Out of
desperation I was about to try to replace the air intake manifold
gasket but someone riding with me today said it seemed like the torque
converter.  Any knowledgeable thoughts anyone?  This trooper is
ruining my life!
