Re: clanking sound that driving me nuts.
Dude, my 97 ZJ does the exact same thing after having my trans rebuilt. Only
does it when it is hot out, long slow moving traffic or slow moving on the
trails. It got so bad once it sounded like a bolt wizzing and gringing
around the scatter shield between the trans and engine block so I shut her
down, removed the access panel to see if the guy forgot to tighten up a torq
converter bolt, but nothing was lose or missing..?? I let it cool for about
an hour, started her up and all was fine..?? Over the months I noticed the
clanking will go away once the torq converter locks up, I even have the
sound on video as I record allot of our trail rides with a bumper cam,
showed it to the dude that rebuilt my trans (from Mr Transmission) and he
swears that sound could not be comming from the transmission... But it IS
comming from the transmission, so I will prolly have to eat another rebuild
sooner or later cuz of that noise..
Now, I do have close to 100K miles on that rebuild though, I change my fluid
and filter every 30K - 40K miles as I am terrably rough on her, and can
drive 400 miles in a bad week for my job while rolling 32" mud tires,
factory gearing and a 4" lift. Very embarrassing to pass other trail riders
as I am sure they think it is a rod knocking, my clanking will get so bad it
WILL make the noise in N or park, the olny cure I have found is to either
stop and let her cool down or drive maybe 30 miles on the highway so the
torq converter will lock then it will cool down on it's own and stop the
noise. I had the trans guy put an external trans cooler with a rather large
fan on it right after I 1st noticed the clanking sound, did not help but I
am sure it did not hurt either..

Re: clanking sound that driving me nuts.
I took it to the transmission guy and he was like, hey, I took it for a
ride, did not hear the sound. Have a nice day. So I told him, man, it
only gets hot in stop and go traffic.
What do you mean when you said "the torq converter locks up" ??

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%.

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%.
