Peter,
Thank you for taking the time to assist me. Very much appreciate what you have done, Now to locate bell housing and pedals. Been on this 5 yrs now starting to see some daylight.

No problem Gary, Let me know if I can provide any additional help.

Pete

Hello Pete,
Getting closer, would you happen to know the ratio on your T5? Are you happy with rpm in 5th? I also am keeping stock rear ratio.

Gary

Custom carpet?

I believe the T-5 comes in generally two flavors regarding the overdrive 5th gear ratio . One in the 20% reduction range and the rest in the 30% reduction range, mine is the 30% reduction range. My rear gear ratio is in the 3.30's , 3.36 if memory serves correctly.
Rpm's on the highway are greatly reduced with the 5 speed when compared to the stock Fordomatic with 70mph coming in right around 2000 rpm's.
I willl say one of the biggest improvements is the fact that swapping from the Fordomatic to the T-5 5 speed shed about 150 pounds off of the front end. The car steers and stops much better now.
The carpet is from ACC (auto custom carpet) , you can order any little bird carpet from them without a hole in it by selecting the "column shift" option. I know the car was never offered like that but their carpet is .

Pete

Thanks for the information Pete . That is a huge help, will check out the carpet supply as well.
Thanks again,Gary

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

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.

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...

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.
