Does Toyota W-56 And W-58 Manual Speedo Drive Interchange
May 29, 2009 I have a 1993 toyota hilux 2.8ltr deisel and my speedo is not working how do i check if my speedo cable is not broken - Answered by a verified AU Auto Mechanic We use cookies to give you the best possible experience on our website. It's finally time to do some speedo gear corrections. W58 trans from mk3 supra n/a 4.30 final drive on ae86 195-60-14 azenis The speedo is optimistically reading about 15% over. Ie, 70kph indicated = 60kph actual. I have to find time to GPS this thing properly on the highway, but that's the gist of it. Toyota Motor Corporation's W family is a family of RWD/4WD transmissions built by Aisin.Physically, these transmissions have much in common (like the bell housing-to-body bolt pattern) with other Aisin-built transmissions, like the Jeep AX-5 and the Toyota G-series.

There would be on other part required, the square drive that drives the sensor, you could make one easy enough. Even if you just chopped the end off a broken speedo cable and soldered/JB weld it in. Hell it might not even need that much, just drop in the chopped bit. From there all that is needed is an electronic speedo in the dash and the correct wiring. It works off the original gear (screws on where the cable went) and I do believe coming from a C series like I found mine that the electric speedo from a corolla would be fine.
All this is hypothetical but I got quite a few PMs asking me how to do it due to people snapping the speedo cable looking for a superior solution. I've got nothing to try it on right now so will have to be a project at a later date.
