727 trans leak @ kickdown band adj nut

[oldsnofear]

Just putting my car away for the winter and noticed a small leak around the trans pan so i replaced the gasket and cleaned it all off.i took it for the last hurrrah road trip and now i noticed i have a small leak at the kickdown front band adjustment screw and jam nut. My question is,isthere a sealing washer under the jam nut? trans was rebuilt 2500 miles ago. Thanks Shawn

No seal

I always put some thread sealent on the them when I build one or make a band adjustment
