Leaking transmission pan

[kiwigtx]

I use stuff very similar to this tin. It is brown and extremely sticky (reminds me of my son's favourite joke - What's brown & sticky....a stick)
Anyway, you 'paint' it on very thin on all surfaces (gasket and pan/trans) - then give about 30mins air dry time. The gasket can be set on the trans first to make life easier, then re-visit after an hour to complete pan to gasket. Then carefully assemble gasket to trans, the pan on gasket. As long as all surfaces are meticulously cleaned with alcohol or similar, you shouldn't have any leaks. This stuff is awesome, because you can actually remove the gasket by simply heating the area where the gasket is seated. :icon_thumleft:

Like others have said i bet you have a leak from a different area and its running down to the pan (making it look like its the pan.) My fill tube was leaking and it appeared like it was the pan.

Now... if its really driving you nuts this is how we find pesky hydraulic leaks (im in the heavy equipment business)

Clean the area thoroughly with elec parts cleaner etc. and assemble. Now..... go get some baby powder and lightly cover (poof) the entire area that could potentially be leaking with the powder. Next, get under the car (with a light so you can look closely) and have someone else fill the tranny. As soon as it starts to leak the slightest drop the baby powder will expose the source as it will turn red. Even the slightest trace amount of fluid will leave the evidence.
