need help with recalibrating my speedo
 

I recently had 373 gears installed. My mechanic told me that I had to buy a hand held computer to recalibrate my speedometer. I called the local speed shop and they said they could use a 21 tooth gear, which they will install in the transmission and they said that it would cost 70.00. I have a 97 gt with a 5 speed transmission, also which is the cheapest and best way to go. Any advice will be helpful. bml

With a 97, you can just change the driven gear on the speedometer cable at the transmission. It'll cost you less than $10 and take about 10 minutes once you've got the car up in the air. 99 and later require either a Speedcal unit or changing it with a handheld/custom tuning.

Could anyone give me the details of putting the speedo gear in the transmission. I was told you have to drop the pan on your transmission. Any help eould be appreciated. bml

Get the car up in the air. You'll see at the tailshaft housing where the speedometer cable goes in to the housing. Use a 7/16" wrench to remove the clamp bolt at the cable/tailshaft. Pull the end of the cable out of the tailshaft housing. Use a small screwdriver to pry the c-clip off the plastic speedometer gear. Slide the gear off the end of the cable. Slide new gear on to cable. Reverse the disassembly procedures to re-assemble. Don't over-tighten the clamp bolt though, just snug it up nice and firm.
Total time once the car's up in the air is about 10-minutes for a first-timer.
