hello Gbody lovers!
ran into a little problem today. had a transmission fluid leak(th350) from a cooler line so i replaced the steel lines with braided lines because why not right . After changing the lines and putting fittings on i experienced a worse leak than i started with. i have pictures of where the leak is coming from but not exactly sure what i need to replace it. i believe we this is the base of the dipstick but not completely sure. if i could pick some brains and get some insight that would be greatly appreciated. (pics attached)(located just below trans cooler lines on th350)

I believe some use an O-ring and some use a rubber boot, and probably being original it is possible the plastic base has cracked and maybe made the leak worse if you bumped it while installing the new trans lines.

yeah the base is cracked and moves freely up and down
Well you can get a new stock replacement or an aftermarket one if you want something a little fancier, just verify length and carb hook up style.
