a-904. Still leaking after rebuild! :(

Since you dont know what it is, you didnt mess with it. That doesnt mean its not in there or loose.
The kickdown band is anchored on its ends. One end to the adjuster. The other to the apply lever. The apply lever pivots on a steel pin which is installed from inside the bell house. After it goes in, a small plug is screwed in behind it to seal the access port. It is on the drivers side, at the bottom. About 5 oclock as viewed from in the bellhouse.
