About Overdrive.....
I have and old cougar 85 with a newer v6. The car has the C5. I want a new tranny in the future. The T5 swap looks very good for the work required, but more possible for me its and OD transmission...but i saw what if i install and AOD transmission in a Normally 3 speed car, the engine wont accelerates good in OD or not produces enough torque to maintain a Cruise Speed (60 or 70mph), because the Differential (2.73) its a "long gear".....i want to know if the swap is safe from a C5 to AOD(any ford tranny) or i need some rear end modifications. Thanks...
