clanking sound that driving me nuts.

Re: clanking sound that driving me nuts.
The inside of a torque converter looks like 2 fan blades really close
together. One is spinning when the engine is turning, and the other spins
when the fluid "spins" from the first fan. This is what moves the vehicle.
The torque converter locks up when the computer detects that the
transmission is in overdrive and the load on the engine and throttle opening
indicate that the vehicle is "cruising". The converter has a clutch in it
which is activated when the computer energizes a switch in the transmission.
Basically what this does is makes the converter a direct drive, much like
releasing the clutch pedal on a manual transmission. It all but eliminates
any slippage in the converter. The benefits are less heat in the
transmission fluid, lower engine RPM under cruise conditions and usually
better fuel economy. By design, the slippage is usually between 5 and 10%.

Re: clanking sound that driving me nuts.
Thanks.
Well, when I had my radiator done, the guy said I should get a flush.
Would it make sense to reason that the transmission is not getting
cooled sufficiently causing the clanking (read my post and responses).
A radiator cooling system flush will/probably help? I am tired of
taking it to the guy and he's giving me the "see no evil, hear no evil"
treating. What noise? I don't hear any noise.

Well, when I had my radiator done, the guy said I should get a flush.
Would it make sense to reason that the transmission is not getting
cooled sufficiently causing the clanking (read my post and responses).
A radiator cooling system flush will/probably help? I am tired of
taking it to the guy and he's giving me the "see no evil, hear no evil"
treating. What noise? I don't hear any noise.

Re: clanking sound that driving me nuts.
Insufficient transmission cooling will usually manifest as burnt, smelly
fluid, slipping and finally outright failure. Clanking is not a common sign
of this, but it certainly won't hurt to flush your cooling system. Lots of
"auto repair technicians" will suggest cooling system flush, oil change,
rotate tires, etc. when they don't know what else to do, however.

fluid, slipping and finally outright failure. Clanking is not a common sign
of this, but it certainly won't hurt to flush your cooling system. Lots of
"auto repair technicians" will suggest cooling system flush, oil change,
rotate tires, etc. when they don't know what else to do, however.

Re: clanking sound that driving me nuts.
I flushed mine a week or so ago and no change at all, still clanks, I am not
as freaked as I was when the sound 1st started though, I almost don't notice
it anymore in the city, on the trails it is totaly embarrassing though. Like
I said earlier I beat the poor girl off road with stock gears mud tires a
lift with about 100K since the rebuild and she still keeps on keepin' on, I
guess I will worry about it once it duz finaly die. Been looking around the
bone yards for a sorta cheap emergancy replacement in case it takes a quick
dump on me with no warning, it's my daily driver so have nothing to fall
back on..
