RE: [DML] Empty Tank (was Re: automatic transmission?)

Ahhh yes the dreaded empty tank syndrome that can fool the best of us! That
can happen when you're using mileage conversion methods (fuzzy math?)
instead of a working fuel gauge.

Peter's description of the symptoms led me to think it was more likely an
engine issue as it's not often an auto transmission causes an engine to
stall. When I started the car the pump immediately gurgled with an obvious
fuel air mixture more befitting the combustion chamber than the fuel tank. I
didn't want to overlook anything however so I attempted to drive down the
block a ways. Not a good idea as I almost didn't make it back to the house!
The vibrating shifter was nothing more than the driveline jerking from a
severe lack of fuel (a human analogy would be you'd be jerking too if your
lungs were starving for air!) and the pump noise tends to transfer through
the frame tunnel so it can be misleading as to its origin. 

I'm glad Peter posted before me as I didn't want the collective DML brain
trust theorizing for long on the most obscure possibilities imaginable over
a case of "empty tank syndrome". To add a car related spin on the old adage
"when all else fails read the directions" or check the gas gauge! All is
well that ends well and I hope Peter has a "Jerry Jug" for some gas cause
that car isn't making it to no gas Sireee!

The pump noise would come from the front of the car, the transmission is
behind the driver. The pump noise would only happen when the fuel tank is
low. You might also have a problem in the fuel tank with the pick-up hose.
it could be partially kinked or leaky and it either can't get enough fuel to
the pump or it sucks air. Glad it worked out to be something simple but the
lesson here is to have Rob fix your fuel gauge and check out the pick-up
hose and baffle in the tank. The "slipping" you felt was the engine bucking
when it didn't get enough fuel, not the transmission slipping. You are
really lucky you are close to Rob and he could make a "house call"!!!!!!

of the external adjustments. If that didn't help then raise the car and with
the wheels off the ground and the motor running in gear, carefully go under
the car looking for the source of the noise. A partially plugged up filter
can "starve" the fluid pump causing cavitation making a noise.

I've been driving it regularly since the snow went away, but just local
stuff around home. I drove it work on Friday, ~25 miles each way. On the way
home, and near home, I had to slow down for a car making a turn. There was
an odd sort of vibrating sound that seemed to come from the back of the car,
and the engine stalled. I restarted, con
