Hey, the 2jzgte motor and aristo auto tranny was installed. My problem i cant figure out why the speedo is off. when i go 60 it says im doing 70 when im doing 70 it says im doing 85. Im getting sick an tired of not having the right mph. Does anyone that have the swap done knows how to fix this problem or what it might be. Is there a sensor that needs replacing? Does anyone else have this problem when switched over to the 2jzgte motor an tranny.

So i find out today, that if your using the stock rear end its going to screw with the mph from the aristo transmission. Has anyone put like a recalibrating speedo sensor on it to fix this. or does any of the other swaped sc if this problem

It's the stock rear end you got. The gear ratios are so high, hence the speedo is off. Time for a TRD Supra TT auto LSD!

I have a Yellow Box from Blackrobotics because I'm using a JDM rear end with the 6-speed tranny, and it works fine with the speedometer because the sc300 speedometer is analog. However, the output logged by my AEM shows the speed to digitally oscillate 4 - 6 mph. Fortunately, the analog speedo filters out the high frequency oscillations; so, it reads just fine. Additionally, when I zero out the Yellow Box, the tranny tail-shaft speed is smooth, as well. My biggest concern is speed based control of anti-lag and 2-step when I correct for the JDM gearing. Both are turned off by vehicle speed, and I'm probably not getting consistent control because the vehicle speed varies so much.

Hey, thanks i think im going to try this yellow box, since i dont have 2k$ to spend on the trd rear end, ring an pinion. Well I guess we will see how this rear end holds up to my GT42.
