yes,I have done that also
clean pan and tranz with brake clean and use the the mopar black atf/rtv
I smear a thin coat on the tranz flange and a thin coat on the pan
not a lot just a good thin coat,let set up 15 mins or so install it
I snug up the bolts with 1/4 ratchet,let cure over night,check agian in the am with the 1/4 ratchet and make sure its still snug
didnt leak till removed
that was in a pinch,I would rather use the new o-ring gasket from the dealer well worth the $ and upgrade to a reusable gasket
used it on all the engine stuff last go round with the sb..VC,intake end seals,wp,t-cover,fuel pump...even glued the dip stick tube into the block
thin coat on the gaskets and no leaks 4 yrs later still...now it blowing oil out the VC breather is another story
