The Manual Transmission Manual
We get a lot of emails from readers who want to know what
all the different Ford overdrive manual transmissions
are, and what is the best  for
their car and engine. So we decided to give you this quick
reference manual to the four most popular overdrive transmissions
for early or late model Fords.
You can see the critical specs and dimensions on the transmission,
and get an idea of the power they can handle. All of the
transmission data listed are for the Ford versions of
these transmissions, but keep in mind Tremec supplied
variations of the same transmission for use in many other
brands of vehicles. So if you come across a T5 out of
a GM car, it will not be the same dimensions as listed
here. We are strictly listing Ford applications only.
If you have questions on installation, whether it will
fit a certain application, bellhousing and clutch requirements,
we suggest you contact Fortes Parts listed in the contact
section at the end of this page.
As an added bonus we've also got the rebuild manuals,
in downloadable form, for those of you who have busted
up a tranny and want to rebuild it! F/M
