AAANYway..... Assuming your T5 is a 93 model, your will have a 8T drive gear on the output shaft, The maximum gear you can correct for without ripping the trans apart (which isnt hard) is 3.55's. That would require you to use the Jeep 23T white speedo gear.

Now if you want your speedo to be correct, you will need to remove the tailshaft housing and swap the gear to either a 6t or 7t gear.

a 6T(black) drive gear will require a 18T(yellow) speed sensor gear
a 7T(yellow) drive gear will require a 21T(red) speed sensor gear

The 8 tooth drive gear combined with the Jeep 23 tooth is a not compatibly combination.
It may work on paper. It may (actually it does) work in reality but after about 20,000km. The driven gear will be chewed up.

Plastic floating around in your transmission is not good.

that didnt get you anywhere NEAR to being close... you are only correcting for 3.27 gears.

have fun racking up the mileage on your car faster than you need to.

I'm not completely sure what tranny is in the car, the PO put a different on in before I bought it. I thought it had the 8T. My speedo is honestly only off ~5mph. I don't know. Either way, I'll enjoy the miles.
