Hello folks,

That ball is a check ball in the factory fill port for filling the transmission casing with automatic transmission fluid. The ball fits in the nipple, and all is covered by a thread on cap and aluminum crush washer.

Also an excellent place to refill the transmission after doing a fluid change.





Note the downward facing cap at the return line connection on the transmission casing.






The ball fits in this nipple.






Refilling my transmission through the nipple and check ball.

Nice pics Seth. What pump did you use for the fluid? Hand pump from HF or a pump with fittings directly from the bottle?

thanks-Hoi

Thanks, Hoi!

I had it all planned out. I had a gallon jug of ATF and a nifty little drill powered pump. It was going to go so smoothly.
It did not. The pump did not. The pump got flung into the nearby woods, with a stream of curse words to send it on its way.

I fell back to what worked. A bottle pump. A hand bottle pump. It worked. But it took awhile to pump 13 quarts of ATF. Twice.





Hand bottle pump. Effective, but SLOW.
