It's possible to work ssl connexions throw a transparent proxy ?

WPAD transparently/automatic *configured* proxies yes. Others, no.

If I set the configuration manually at the browser, works perfect.

Of course. When the browser is aware of the proxy it uses an HTTPS-over-HTTP protocol (via CONNECT requests). Squid supports that HTTP request type. Port 443 uses an HTTP-over-SSL protocol designed to prevent transparent proxies capturing the *secure* traffic.
