  • Installing Gtr Speed Sensor On Rb25 Transmission

    Some of you know, I recently had an RB25 transmission installed in my GTS to fit the RB25DET engine.

    And its known that unless some modifications are done to the speed sensor system, the speedo won't work.

    As a result, I got a hold of the following parts from a respected seller:

    1. GTR speed sensor casing
    2. GTR speed sensor gear (a metallic rod with red gear on it)

    Now I need to know HOW to install it. I am still running RB20 wiring and the speedo is of course RB20. I was told that RB25 tranny has electronic sensor in it and the RB20 one is mechanical and that the only way to make it work is to use a GTR sensor.

    My question is: Does anyone know HOW to do this? If someone else has already done it, please share.

    It sux to drive on the road, while looking over your shoulder all the time :hit newb:.

        Well you take the r33 gear off the speed sensor, take it off the gtr one and put the 33 gear on the gtr one as the 33 gear is different from the 32 one. Once doing this install it in the trans hook the speedo cable up and call'er a day!

        But ya what's up with all these old post revivals lately?

            Just to be sure, I have the same problem, so with a GTR speedo that I fit the RB25 gear on it, it will work fine?

              That's what I have done and mine is in good working condition and no problems. I'm saying it worked for me and everyone else I know with the 25 swap, it should work for you as well!

                  Good write up. I just tried to explain things quick. I didn't want to make this thing go on and on. This is a very easy fix even though it sounds complicated
