727 Tranny Dipstick Question

[1970 RT/SE]

Looks like my tranny is leaking at the dipstick. If memory serves me correct there is an O ring that attaches to the bottom of the dipstick. My question is where do I get a replacement O ring  or is this am RTV solution?Thanks for any help.

The O ring is .750" OD X .100" thick. RTV around the existing O ring is acceptable but be sure the fluid level is below the O ring and the bore/tube are dry before applying.

In some rare cases the tube will crack at the O ring groove and repeated replacement of the O ring or RTV won't stop the leak...look closely at the groove.

Your favorite local auto parts store should keep them in stock.
