hey i have a np 205 to th350 adaptor i just bought and the rubber "seal" on the one side where the coupling passes through is pretty messed up the other side seems okay. i need to know if these seals are made to be replaced and if so where could i get one. the reason i ask is a tryed to pull out the one that is messed up and it started to rip so i didn't know if maybe they need to be driven out or what??? i believe they are there to keep the fluids from interchanging but i'm not sure. any help would be great

the seals are made to be replaced, and need to be driven out. one is placed in each direction to keep fluid out on either side.

Does anybody have the part numbers for the two coupler seals and the large square o-ring on the outside of the th350/np205 adaptor? Also, will a Napa have them, or do I need to find a trans shop?

Thanks for any help -Brian

Just drive the old ones out and get the part # off of them, any parts store can cross reference seal brand part #. (Oreilly's here has 'em on the shelf)

dont forget the 0-ring on the inside of the coupler on the 205 input.

CR19760 is the part number for the seals (you need 2) that go in the adapter between the th350 and np205 on my '71 K5. Anyone have the part number or size for the one inside the coupler?
