Is Lucas transmission additive any good I used it twice in two
different Chrysler transmissions which had some problems and
they died 3 days after Was this a coincidence?

Answer: Why it Failed

Transmission fluid must circulate freely and in great quantities
to cool, lube, maintain pressure the system needs. Restrictions
to this can ruin a transmission in short order.

Additives solve many transmission problems. Some brands stop seal
leaks. Other brands smooth rough shifting, speed up slow shifting,
and cool in several ways - reducing hot-spots of friction,
and by removing a coating residue, which permits heat transfer
to the outside.

This is what I think happened.

A good additive would have more or all of those features, and a
less desirable one would have less. I have lots of experience
selling different kinds of additives and I get feedback on all
this. This is what I think happened.

Lucas is a honey-like liquid. If this substance was added to the
transmission with the motor off, no transmission fluid would be
circulating. The Lucas product would not have had opportunity
to be agitated and blended in with the moving fluid. It would
just sit there at the bottom - where the fluid pickup screen
is located.

That would mean trouble maybe. Lucas could choke-off the the
fluid inlet - as that is where the fluid inlet opening is. What
Lucas was sucked up, if any, when you started the motor, may
have been so stiff it may not move onward. Or not flowed like the
watery transmission fluid would. Maybe, it blocked the flow.

With no fluid in great quantities flowing, due to the honey-like
nature of Lucas, or if the Lucas product was a solvent,
not the honey liquid, and the solvent washed the guts of
the system clean, bits of sludge containing clutch fibers may
have floated free and these could have choked off the screen,
and blocked the tranny fluid flow.

Other than bad timing in your case - twice in a roll, those are
two often-seen conditions when the transmission is taken apart,
inspected, and rebuilt.

Good transmission additives, those made from a quality standpoint,
would have an ingredient called a dispersant - in addition to the
ingredients needed to clean, cool, free sticky parts, friction modify,
and so on. Dispersents prevent what's loosen from reforming to prevent
blocking of the pickup tube and arteries in transmissions and engines.
