I got my 3.73 gears in today, but I have yet to change the speedo gear (still being shipped to me). I tried driving in traffic relative to what they're driving, but the results were inconclusive. So the question is, I've got a 92 LX Vert that is an AOD, and I switched to the above mentioned gears, if the speedo says I'm doing 30 mph, anyone know how fast I'm really going?
