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.

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

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.  

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.   

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

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.

Miker, with an aluminum flywheel, it is expected that you will require more throttle and possibly slipping the clutch to get it moving.  A heavier, or stock steel flywheel will store more energy and get the car rolling much more easily and will be much more pleasant to drive on the street.

With the exception of truck 4 speeds, All T5's have shorter 1st gears than any transmission that was ever factory installed in any Y-Block equipped vehicle.  So, if the stock transmission got it moving easily, then a T5 will also.  This again points to the issue being the aluminum flywheel, rather than the transmission.

The T5-Z is the only one for Ford with a 2.95 1st gear.  That is an aftermarket transmission which was never factory installed in anything.  While it is absolutely possible that you could have one, it's not very likely, unless you bought the transmission brand new.  Every other T5 is shorter than that for 1st gear, once more pointing to the flywheel.

For street use, you want the rear gear to be something that has the engine at a favorable spot in the powerband in overdrive, usually somewhere between 2000 and 2500rpm.

IF you've got a newer T-5 produced by TREMEC instead of Borg Warner, this link will provide the listing of TREMEC ID numbers

The link below provides a comprehensive history of the mechanical differences in the T-5 over it's 30+ years of availability from Borg Warner and subsequently TREMEC

IF you want more technical info. with good pictures about the differences in the T-5s over time and things to be aware of in going through one for 'tune-up' purposes, this is a GooD article to read if you're interested...

Something I didn't see mentioned, but that affects the rear end ratio. There were also different 1st gear ratios in T-5's. My unit is 2.95, IIRC, but a lot were 3.21 or so. Different 2-3 also. So when you pick the rear end ratio and o/d ratio, know what your first gear is. My 2.95 with a 3.73 and an aluminum flywheel, 26" rear tire, takes some throttle and a little slipping to get started on a hill. And the birds fairly light.

Nice article and thanks for the information.  Do you have any pictures of the mods to the transmission mount.
