You should have put 2 1/2 qts in the converter. Sadly you will be forced to
pull the tranny again to add the missing 1 1/2 qts. If you even have to
think about my reply and wonder whether it's accurate You should do that car
a favor and sell it..... or at least promise it that you won't ever open its

I wouldn't worry about that being the cause of your noise.
One quart should be plenty to lube it during startup which
is the big thing. The converter snout drives the pump which
has a pretty high capacity and will fill the converter
almost immediately from the pan even if you do not
pre-charge the converter. The converter is one of the first
places fluid will go in the trans. Make sure the trans has
plenty of fluid in the pan when running. Only have about
half way between fill marks when cold idling. If you still
have noise, your problem is something else besides failure
I would be more concerned that you did/do not have the
converter properly engaged in the pump when installing. It
can slip out of position very easily while installing the
trans. If you have to pull the trans up to the engine with
the housing bolts to install, you have a problem. You
should be able to work the converter back and forth a little
with your fingers after the trans is bolted up and before
the converter nuts are installed. If you can't do this,
something is not right. If you have started the engine with
it in this condition, you may as well pull the trans for
repair before you do any more damage.
Lugnut, I'm afraid that your absolutely correct. I was very aware of
engaging the torque converter completely but like you said it probably
slipped out a bit before I bolted up the bell housing. Out the tranny
comes!! groan!! Thanks for your answer As you know, there isn't a lot
of clearance fitting an FE/C6 in a 67 Mustang.

Another word of warning is about the engine thrust bearing.
About half the time when this is the problem and the engine
has been run, it damages the crank thrust bearings in the
engine as well as the trans. Make sure you check the end
thrust on the crank before you put it all back together. If
the thrust bearings are damaged, the engine may not survive
long before crank bearing failure. If there is any question
about what you find when you check the thrust, pull the pan
and check the bearing. It will be a lot less work now than
later when it scraps itself a long walk from home.

You will need to pull the main brg with the thrust bearing
for inspection. If all is OK there, you can simply
reinstall the bearing a torque it up. Make sure the engine
still turns as it should after re-torqueing. You should
have the spark plugs out to turn it. Sorry if it sounds
like a lot of work but, I have already seen several screwed
by ignoring the possible problem. If the thrust is bad you
will be able to see it. I would check the crank thrust with
a dial indicator before pulling the pan. If this has been a
running engine - not a fresh build - it may be OK with no
need to open it up. Keep in mind that an engine in front of
an automatic does not have normal loading of the thrust like
a manual trans with a clutch. As long as the thrust
clearance checks OK, it should be good to go. If you prefer
pulling the pan for a visual, I can only say it is better
you than me. That's a lot of work on that car and the dial
indicator method to check it is much easier.
Don't feel too bad if the converter slipped out and you damaged the trans. I
it...once. I guarantee you won't make that mistake again. Especially in a
an FE and a C-6!!
Next time you'll spend 2 hours making sure the converter is seated properly,
you'll still be paranoid when you start it up. ;)
Usually, the damage is limited to (only?) the converter and front pump.
check the crank endplay, but usually the pump input gear breaks and saves the
On a C-6, I would put 1-2 qts in the converter and 4-5 in the pan. Running a
with this much ATF in it will be ok. Once you start the motor add 2 qts as soon
safely possible, then top off as needed. IIRC the capacity is ~11 qts from dry.
Good luck. There's nothing like an FE in a Mustang. :) :)
The ironic part of this, is that I remember my
brother-in-law doing the same thing about 20 years ago so I was very
aware of making sure the torque converter was seated and I still got
