This is the most straightforward option, but it can also be the most expensive. Electronic speedometer conversion kits are available from a variety of aftermarket manufacturers, and they typically include all of the necessary components, such as a new speedometer, a speed sensor, and a wiring harness.
Option 2: Use a mechanical speedometer adapter.
Mechanical speedometer adapters are less expensive than electronic speedometer conversion kits, but they can be more difficult to install. These adapters allow you to use your existing speedometer with your new transmission.
Option 3: Reprogram your vehicle's PCM.
If your vehicle has a programmable powertrain control module (PCM), you may be able to reprogram it to work with your new transmission. This is the most difficult option, but it is also the least expensive.
Here are the steps involved in installing an electronic speedometer conversion kit:
1. Disconnect the negative battery terminal.
2. Remove the instrument cluster.
3. Install the new speedometer.
4. Install the speed sensor.
5. Connect the wiring harness.
6. Reconnect the negative battery terminal.
7. Test the speedometer.
