Yes, it is an aftermarket bought new, but some years ago. 2.95 first, and the .8 something o/d. I drove it for years behind the steel flywheel and put the aluminum one in when I redid the motor a year ago. I'm perfectly happy with it. Seattle has a lot of hills, my typical drive has 500 feet of elevation change in 10 miles, so maybe I just notice it more. Due to the cam, my motor likes 2500 as a minimum.

The links Noshortcuts posted is the real answer. I just wanted to point out the variety of ratios, and I missed torque ratings, that have been available over the years. Tire height, rear gears, and terrain effect both ends of the drivability.

hey bud do you a video of this trans swap. trying to find a video that was on here a few weeks ago. trying go do the same thing. did you have to cut the floor to make room for the shifter

5 speed conversions I've seen have the shifter coming out in the middle of the tunnel, so yes you have to cut a hole and fill the old one.  The good part is replacement carpet is available for the conversion.   

Th e z spec   T% was not  the only one  avalable, the  first  5T Trans that was in the V8 Mustang in 1984 and 5 was a 295  1st gear ratio. It  it was  before the World class series T5 and was not  known for  being vary strong!    There are  4 cylander  5 speed  transmissions with a 1st  gear of around 4 to 1  the work quite well in a normal driving  situation, of coarse they won't stand the  abuse a properly modified  V8 Transmission will take.  

where would I find the real answers section im having a hard time finding it

Go back to the previous page on this old post, and see the links posted by noshortcuts. They all still work, I just checked them.

There’s also an a very long set of t5 articles on the HAMB.
