Leak at speedo cable.

It should be mentioned that the big O ring on the adapter is not a standard O ring. It's made of a special material that's designed to swell once it's exposed to the trans lube. This makes it seal tighter but also makes it a non-reusable part. If you reuse it you run the risk of damaging it when you put it back in. The proper O ring is red. I tried to get one from a Mopar parts department & the parts guy said I had to buy the complete adapter (I think he just didn't know how to read the parts books or something!!). I was able to get the proper O ring from a local parts house for les than $2 and even ordered a couple of spares to keep handy. Of course, I've got no idea where they are now! :angry2:
