So Jim, maybe you can help me understand this. When I am cruising along at
65 and want to pass somebody, the truck seems to shift two times. I know
one would be to get out of overdrive but what is the other?

Why hasn't anyone told this gentleman what the torque converter is for?
Frank, the torque converter replaces the Clutch in an automatic
transmission. It is
a fluid coupled device that works like two fans face to face. Turn one fan
on ahd
the wind from it will turn the other.
Submersing both is a fluid will improve the coupling. Your torque converter
is full
of transmission fluid. The insides are not like fan blades rather like a
turbine
with 3 parts in it. One turbine is connected to the flex plate (flywheel)
and one
is connected to the input shaft of the transmission.There is usually a third
element
between the others with slanted blades on it to help increase the torque
transfer.
I suggest you find a transmission manual like a mechanic would use and study
the
inner workings of an automatic transmission and the torque converter. Not
to make
this any longer than it already is, the answer to can changing to a
different torque
converter make your truck run faster is no, BUT it can make it accelerate
from a
standstill much faster. The use of a "high stall" converter allows the
engine to
quickly rev up to a higher rpm where it makes more torque and gives you a
faster get
a way. If you go too far with the stall speed you may adversly effect the
drivability of your truck. It can cause the engine to stay reved up at
lower speedl
like you were in a low gear. There is a clutch in modern automatic
transmissions
especially those with overdrive that engages at speeds over about 40 mph on
most
veichles to improve fuel economy.
Just a quick note about early auto trannys, some only used a torque
converter insead
of gears.
Early Buick Dynaflow before 1955 and Chevrolet Powerglide before 1953 were
som
examples of these. You needed a lot of power to get moving in these
innefecient
designs. Buick had the power, Chevrolet didn't!!!

Somone on the list also suggested that I change the torque converter to go
faster.
Once again, I have no clue about this componant. All I do know is that is
it kinda
like a pump for the trans } fluid. (I think)
