Ferrari Mailing List: Re: Help with transmission leak

[Hans E. Hansen (FList]

Where is it leaking?

Pan gasket?  (which would be easy to fix)
Input seal?  (Minor difficulty to change - tranny pro
could do it in 1/2 day on a "regular" car.  400i, I don't know)
Tail housing seal?  (should be easy to change.)

Unfortunately, most TH400 leaks that I've seen were in the
input.

I don't know of a 'stop leak' product that I would trust, but
try getting an estimate from a tranny shop.  It might not be
that bad.

Hans.
