Rallysnake/Jarendall....Yellow 7 tooth inside drive gear is definitely off to the side of the hole and not centered. Must be the issue and it will most likely have to go to a trans shop.

I am sure it is a T5 as the tag number of my trans 1352- 251 07455 jibes with that shown for the T5 Z on the Forte's parts connection website (www.fortesparts.com)

The Rockland Standard gear invoice that came with the car lists the trans gearing as 1st=2.95/OD=.63. this gearing is consistant with T5 world class specs and along with the yellow 7 tooth speedo gear inside all point to it being a T5 world class. (Also, the car was advertised by the previous owner as having a Tremec T-5 when I purchased it.)

However, I have been looking into the electronic solutions also. As my Backdraft has a speed sensor pickup in it's BMW rear end, I my get lucky.

I found an electronic (little black box) product on-line called Cablex (www.gaugeguys.com) that will pick up an electronic speedo signal and convert it over to drive a mechanical speedometer. A little steep at $295.00 but would eliminate tricky cable runs, cable binding. etc. and more possible problems later. Might prove to be a good solution for others in the future.

I may also use the same approach but with an electronic speedo only, but only if I can find one that matches my other Autometer gauges. I'm wondering,does anyone know if Autometer makes a eletronic speedo that matches with the original mechanical type in looks?
Have to compare costs of tranny pull and gear fix vs the electronic solutions.

Also, I looked at the link regarding speedo gearing, etc found it very interesting......Thanks again to all..ox_ford_guy
