There is no local transmission shop either, hence the dilema.

All solved now.

Gave the newer application to the dodge store , as per johnrr. Got the newer seal easy then. They knew the number for that one off the top of thier heads.

I like that the newer seal also had a lip on the metal part so it couldn't be installed wrong, depth wise. Just tap it in, and it's all good.

Started the R and R at 3. Drove it home at 6.

Thanks again Moparts. Awesome, as always
