An Expensive 60 cents

[69Ford]

Ok to start out with I have a C6 tranny and the pan gasket leaked. Removed the pan cleaned both mating surfaces well, new filter and gasket still leaked. Did the same thing again less filter still leaked. So now I start really looking tranny fluid all around the gasket sure looked like it leaking again from there. Then I noticed it was wet around the dipstick tube at the tranny which is hard to see. And since I had the tranny cover off in the cab that gave me access to the bolt holding it on. I pulled the dipstick tube out. The rubber O ring was there but really hard. Replaced the 60 cent O ring put it back in and no more leaks. Told my brother about this and he said my dad replaced many pan gaskets and could never get the leak fixed. If he had only known.

Thanks for sharing. Learning stuff like that here is much better than learning the hard way.

WOW, same problem. I installed a rebuilt auto and used the same dipstick tube from the old tranny didn't think about an "O" ring and it still leaks. Now I know what to do!
Thanks for the tip.
