Hi

I own a Westy 87 with an automatic transmission. Right now I have a slight
automatic transmission oil leak which append mainly when the motor is hot.
My mechanic said he does not touch transmission and was not able to locate
the leak (my vehicule had a oil treatment last fall). Any idea where it
could come? Any common problem on transmission leak? Is it always big bucks
to fix a leak on a transmission.?

Thank you
