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
