Clatter in my stall
I assuming you mean chatter , Im not sure who made the 3400 stall you have but if its just a chatter like feeling on lock up you may try a product like lube guard or smart blend and some people have use a couple of the little bottles of posi adiditive for rear ends but its hard to find and that may help if not you may have a converter clutch failure progressing

As I said you can try the lube guard or smart blend additives , But beyond that I would contact fuddle about it ,

Set minimum TCC duty to 98% across the board and
if you are still slipping, increase the TCC Locked line
pressure adder (or jack around the force motor table
to get more pressure at light loads, if your tuning
tool does not have that feature access).
Some clutches don't slip all smooth and quiet like the
stocker is meant to. You trade "grab" for "quiet" and
it's not Grandma's Oldsmobile anymore. If it's trying to
grab and you don't give it enough pressure to work
with it may skip / chatter while it drags (at best) or
chew itself up slowly (at worst). Either make it lock
or keep it unlocked, for best wear life. That would
maybe mean getting into the TCC lock/unlock tables.
With the TCC duty and force motor changes mine
has no chatter and will hold lock without flare, out
past 25% TPS. I think I've felt it slip once when I
pushed into it slowly, further up. You want to get
the unlock to happen before torque overruns the
clutch holding capacity (at given line). More line
or unlock, if you find locked slip. Takes a while to
get it bedded in properly and every different clutch
diameter, material, fluid, input torque and delivered
line pressure means a different tune.
Or you go with a slip-friendly clutch system and
hope you can get the locked holding qualities you
want in a small diameter clutch.
