My brother and i are having a discussion

So my brother and i are having a discussion about his 06 Ford focus 5 speed. He insists that 5 gear is over-drive i insist that it is just fifth gear. Just because fifth is .76 -1 he insists that it is OD.

I've always kind of assumed 5th was overdrive just because they are completely useless gears other than cruising down the road.

Yep 5th is OD. Any trans gear that has a ratio of less than 1:1 is a OD gear. ;)

Usually if the gear ratio is less than 1:1, it is considered overdrive. :D

Tell him the 5 speed you were thinking of was in a Ford F8 truck, not Focus.  :D

Tell him you were thinking of 5th gear on a 6 speed car.

Really depends on what gear is in the rear!
6th might be worthless.

The rear end gear (or final drive in a FWD car) has no bearing on overdrive gears. Any gear ratio with less than 1.00 ratio is an overdrive, including 5th gear in most 6-speed trannies (yes, the T56 are double-overdrive). It's called overdrive because the output spins faster than the input.

FWIW, many older 4-speed truck trannies are OD as well in 4th gear (3rd is the 1:1)

I'd LOVE to have the Tremec T-56 tranny in my car, I'm an economy kinda guy and think that would work GREAT, I dunno what my orginial transmission weighs (Ford Focus) but I know the T-56's are about 130 - 150 lbs. and Expensive, about $2,000 used.

I too must inquire, what is Upduction?

Unless this is a April Fool's joke (Which I am suspicious that it is)

I've never heard of it.

I could get one from a camero with the adapter plate and use a ford pressure plate with a corvette clutch, while using a regular t-5 bell housing. I figure it would cost me $1300 with a used tranny.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.
