Speedometer Issues

[02' hawk]

I have a 02' T/A that has a TH400 that is built with a trans brake. The problem i have is that the speedometer is WAY off. I noticed that there is an electrical output already installed in the tranny that will plug into the factory harness. What can i buy to program the computer to read right? Can the dealer do this?

You may want to contact a dealer and see what they say.....they should be able to calibrate it, however I don't know for sure

The dealer said that since it had a SC he would not touch it. What a bounch of dicks
