Cherokee with horrible clanging noises.
My 95 cherokee 4.0 HO 4 speed auto has started making some truly awful
banging noises. sounds like a mechanic is trapped underneath and is randomly
hitting things with his hammer to attract attention!. (I checked-no there
really isnt anyone there.) motor runs fine. starts fine. only when idling
under no load i.e. neutral/park when hot does the banging clattering start.
when starting from cold is ok until warms up. as soon as I go into drive or
reverse it shuts up. I'm thinking that either the flywheel or the torque
converter has come loose. when cold there is enough drag on the transmission
to hold it against the bolts, but when the fluid warms it thins and gives
less resistance and so things start bangin away. I'm thinking that when
drive is engaged it is enough to hold things against the bolts. Note: all
this is with the vehicle stationary. on the move it is absolutely fine until
I back off the gas and it starts banging away on the over run.
ok, enough of the symptoms, heres what I'm planning to do and where some
advice is needed. I was going to pull the tranny, so I looked in the book to
see whats done and heres whats made me think.
1-disconnect negative cable of battery.
2-raise the vehicle and support it securely
3-drain the transmission fluid then re-install the pan
4-remove the torque converter cover
5-mark the relationship of the torque converter to the driveplate with white
paint
6-remove the torque converter to driveplate bolts.
and so on etc.
If I am reading this correctly, does this mean that I should be able to gain
access to the bolts without actually removing the transmission? The book has
no pictures or diagrams to help on this area. I've had an admittedly brief
look underneath and couldnt figure it out (but I didnt spend any real time
under as the weather is not pleasant at the moment.)
Anyone any ideas or opinions or links to any relevant pictures?
TIA

Check your motor and tranny mounts
http://revbeergoggles.com/motormount/
Check to see if you fan is eating the radiator shroud.
Then check your exhaust pipe mount by the tranny and
if the pipe is banging into the rear axle.
The key word you use is "random" mechanical failures in
the drivetrain generally produce bangs that are directly
related to engine RPM. Random bangs can be caused by
the engine rocking against busted motor mounts or missing
bushings.
Flywheels don't come loose without taking lots of other things
with them. And since you can start the Jeep it's not broke.
The torque converter is nearly indestructible. That's not to say
that something isn't wrong in the tranny, but I'd check a few more
places before pulling it.

Re: Cherokee with horrible clanging noises.
The bolts on the flex plate are known to come loose. That causes a rod knock
type noise. The flex plate is bolted to the crank and the torque converter
is bolted to that. the latter bolts come loose and can be checked/tightened
by removing a plate in front of the bellhousing just behind the oil pan. The
tranny stays in the jeep.
