Re: automatic gear box-general questions

Hi,

I've got a '74 automatic, and I find that when it's cold, the transmission
is really smooth. When it gets hot, the thud when selecting drive or
reverse, or when slowing down gets noticeably worse. Could it be something
to do with the viscosity of the gearbox oil?

By the way hello everyone, this is my first message, having joined the
digest a few weeks ago.
