I'm beginning to believe everything about a Ferrari is about 10% off. That's what makes them so great.

The only way to calibrate it is to send the speedo itself off to a repair center like Palo Alto. The sender is on the passenger side of the trans. You need to use a deep socket as to not damage the wire lead. I took a short socket and cut a small piece out of the side of it for the wire to stick out. And I would recommend replacing the seal ring too. philip (Fanatic1) Junior Member Username: Fanatic1 Post Number: 223 Registered: 2-2003 Posted on Thursday, May 15, 2003 - 1:20 pm:    thanks martin.......I'll check it out.....hopefully it won't too complicated.....thanks for the input!

Philip, if you stand behind the engine looking in on your left hand side you will se a small wire coming from the gearbox. Towards the bottom, this is where the whole thing starts. I presume the sending unit sits in there. Hard to get to.

Is this to fix the speedo measuring the wrong speed? I did some testing the other day while out on the interstate. When the speedo says I'm doing 80MPH I was really doing around 74MPH. I would like to fix this if possible. I assume this incorrect speed effects the actual mileage. philip (Fanatic1) Junior Member Username: Fanatic1 Post Number: 222 Registered: 2-2003 Posted on Thursday, May 15, 2003 - 10:30 am:    Hi guys, Gonna replace my speedo sender tonight...hopefully.....can anyone tell me where the sender is located, process on changing it...a basic how to..........that would be great!!! 1993 348 Speciale............
